Suunto Ocean: Two-minute review

Suunto has been working hard in recent years to innovate when it comes to smartwatches, and its latest dive watch carries on that trend with colossal improvements over its predecessor, the Suunto D5 (a watch that I personally own and dive with, so one that I’m pretty au fait with).

Like the outgoing model, the Suunto Ocean has a relatively small 1.43-inch AMOLED display, which works out to be 36mm. That sounds small, but the high-definition, circular display with automatic brightness adjustment makes it feel more similar to my 49mm Apple Watch Ultra 2 in terms of readability, so don’t be put off by this.

All models benefit from strong sapphire crystal glass, but the stainless steel case doesn’t offer as much protection from accidental dings as something like a Garmin Fenix 8, which is available for a similar price with titanium. We’d like to see titanium used in future Suunto models for better longevity, which is clearly an important consideration for the Finnish company Suunto quotes 11.63 CO2e emissions for the Ocean’s production, which are offset via a reforestation project. For reference, Apple claims 12kg of CO2e for the Ultra 2 with the Alpine or Trail Loop bands (not the bands built for scuba diving), so Suunto’s work to reduce emissions here is commendable if we take it at face value.

Among the 95+ activities you can track, in addition to sleep and recovery tracking, the main reason you’ll be considering a Suunto Ocean is for its dive-specific capabilities, including support for air and nitrox all the way up to 100% oxygen. You can configure five different gasses, but if you’re into pushing the limits, you’ll notice a lack of support for more advanced systems like rebreathers or trimix (a blend of oxygen, helium and nitrogen).

Handily, if you’re upgrading from a Suunto D5, then you’ll be pleased to know that the Ocean works with that same transmitter. If you’re buying new, then the Suunto Tank Pod is sold separately for around half the price of the watch (prices below).

Away from all the technical stuff, the Suunto Ocean is also a great option for freedivers and holidaymakers who just want to track their snorkeling expeditions with one of the best swimming watches. It’ll track you all the way down to 60 meters, which is above recreational limits. That said, the watch itself is physically rated all the way down to 100 meters, so it would be nice just to have that same amount of support for diving activities. After all, why cap it?

Our favorite Suunto Ocean feature is a new one to the industry – sure, if you're an experienced diver, those familiar dive profiles are extremely helpful to help you identify trends, patterns and potential causes for concern throughout your dive, but the watch will also use data from its sensors, like the gyroscope, to map out your dive in 3D.

In our experience, it wasn’t always completely accurate, but you’d expect this from a first-generation product. Even having an idea of where you’ve been on a map throughout your 40-minute dive is nothing short of a game-changer because it helps you to visualize an environment that offers very limited visibility when you’re in it (sometimes centimeters rather than meters).

Even though it handles land-based activity and sleep tracking, the Ocean’s battery life far exceeds the D5’s 6-12 hours of dive tracking. Suunto now claims 40-60 hours of dive tracking, or up to 16 days of regular smartwatch mode. That’s considerably more than the 30 hours’ dive tracking offered by the ultra-high-end Garmin Descent Mk3i.

On that note, the Suunto Ocean ships with an old-school USB-A charger, which doesn’t quite live up to modern standards. We’d like to see it upgraded with a USB-C connection, given that the world is moving that way. Remember that Suunto is all about reducing its carbon footprint, and that should extend to e-waste.

Our test watch also arrived with a short strap, which wasn’t long enough to go around a drysuit sleeve and might not be so good for wetsuits either. Given that it’s designed for diving, it would be good to have a longer strap included in the box. Still, you’ll want that shorter strap for when you’re not diving.

Just like any other piece of diving equipment I test, the Suunto Ocean had several outings at the dive club where it was inspected (in great detail) by many members. In this case, it led to a sale, with one member choosing to upgrade after witnessing the crisp, color display underwater and hearing about the impressive land activity tracking and battery life.

I think that just about summarizes my experience living with the Suunto Ocean, too – it’s the perfect blend of (relative) affordability, function and design, so it’s a really easy one to recommend to any recreational diver.

Suunto Ocean: Price and availability

• $899 / £725 / AU$1,399
• Suunto Tank Pod: $439.95 / £320 / AU$549

Suunto’s flagship dive watch, the Ocean, costs $899, which puts it on the more affordable end of fully fledged smartwatches. It’s more than the Suunto D5 ($649), but it does the work of two separate watches and still manages days of battery life, so you could save some cash versus buying two separate systems.

Garmin Instinct 3: One minute review

I know the Garmin Instinct 3 has a lot to live up to. After all, the Garmin Instinct 2 received a rare, coveted five stars in our official review. With a variety of sizes (from 40mm to the Instinct 2X Solar at 50mm), solar-powered and non-solar versions, a smorgasbord of fun colorways, and – my personal favorite – a hybrid Garmin Instinct Crossover, there truly was an Instinct 2 for everyone.

The Instinct 3 runs along very much the same lines, with a selection of cool colorways, a variety of sizes, and two key screen options. The smallest 40mm size is called the Instinct E, and is most reminiscent of the Instinct 2: there’s only the MIP (Memory in Pixel) option with no solar charging and no flashlight. In 45mm and 50mm sizes, you can choose between a bright, smartwatch AMOLED screen and a classic Garmin MIP screen equipped with Garmin’s Power Glass solar charge technology, offering ‘unlimited’ battery life in bright enough conditions, if you’re out and about with it exposed to sunlight for several hours.

It only really makes a big difference during endurance exercise on sunny days, when it can slow down the GPS mode’s drain on the battery life, but it’s nice to have. We got the AMOLED 45mm version to test in its cool, minty Neotropic colorway, but I do have a soft spot for the digital watch-esque MIP screens that the best Garmin watches used to use as standard. As is, this feels more like a Garmin Forerunner 265, with limited map capabilities, although the case design is still stereotypically Instinct.

The Instinct series has never offered the full-color topographical maps more premium watches in Garmin’s range have, and I was wondering if the AMOLED screen meant we’d finally see topographical maps on an Instinct, but there are no maps or touchscreen here. I suppose Garmin has to distinguish between the ranges and keep the Instinct’s price down somehow.

The Instinct 3 has handled all my training with accuracy, and was as intuitive to use as the Instinct 2. It was easy for me to replace my daily Instinct Crossover with this with barely three minutes of setup, seamlessly taking over with my sleep tracking, Body Battery and Training Readiness scores from my old watch.

Overall? As a pre-existing Instinct fan, I love it. It’s fast, it’s bright, it looks fun, and most importantly, it’s useful. Yes, it’s chunky and plasticky, and if you don’t like the old design, you won’t like this one either. But it’s not a sleek metal communications tool: it’s a toy, and it’s best played with outside.

Garmin Instinct 3: Price and availability

• Instinct E starts at $299 / £259 / AU$549
• 45mm Instinct 3 starts at $399 / £349 / AU$829.
• 50mm Instinct 3 starts at $449 / £429 / AU$929

The Garmin Instinct 3 is available now on Garmin’s website and other retailers, slightly confusingly with five different prices, depending on which model you pick.

The cheapest Instinct E is available now for $299 / £259 / AU$549. The 45mm watch starts at $399 / £349 / AU$729 for the MIP Solar screen, rising to $449 / £389 / AU$829 for the AMOLED screen option. The largest 50mm watch with MIP Solar screen is available from $449 / £429 / AU$829, rising to $499 / £449 / AU$929 for the AMOLED screen option.

It’s cheaper than most Forerunners and Fenix watches, although it does make up for this by using less premium materials and skipping some premium software features. Overall a good value package, but not ludicrously so, especially compared to some of Polar and Coros' cheaper offerings. You won't be disappointed by the price, but it's not quite a steal.

• Value score: 4/5

Garmin Instinct 3: Specifications

Below are the specifications for our review unit, the 45mm AMOLED Instinct 3.

Garmin Instinct 3: Design

• Chunky polymer casing
• Choice of screens
• Intuitive, unchanged Garmin layout

The Instinct 3 builds closely on the design legacy of the Garmin Instinct 2, and the casing looks mostly the same. It’s got loads of colors, it’s roughly the same thickness, roughly the same weight (with just a gram of difference between the 45mm Instinct 3 versus the 45mm Instinct 2), and it’s still got five buttons and similar bezel indentations. The main differences are the metal accents, the new AMOLED screen option, and the flashlight, neither of the latter are available on the smallest Instinct E.

The new AMOLED screen is clear and bright, although it's not a touchscreen. I like the default watch face layout, although this is easily changed, and navigating around the watch with the five-button control interface is intuitive for me (a regular Garmin user) even if my Apple Watch-wearing fitness writer, Stephen Warwick, was offended at the lack of touchscreen.

While Garmin’s Forerunner, Venu and Fenix watches have adopted the hybrid of buttons and touchscreen, it’s another feature missing from the AMOLED Instinct 3 to keep it affordable. The same could be said of the chunky ‘fiber-reinforced polymer’ (read that as ‘thick plastic’) casing, with slim metal accents the only thing separating it from being too childish for some users. Metal screws give it a rugged edge.

Functionally, the heart rate and skin temperature sensor array have not been given a slight upgrade, with the watch still sporting the Elevate Gen 4 heart rate sensor instead of the more accurate Gen 5. Garmin should really have included the up-to-date sensor, even if it skimped on a couple of premium software features. The universal Garmin proprietary charger remains the same, only with a newer USB-C cable instead of USB-A, as is standard with most Garmins now.

• Design score: 4.5/5

Garmin Instinct 3: Features

• Almost all of Garmin’s wellness features
• New torch is useful
• Basic directional maps

For the uninitiated, opening a Garmin watch and scrolling down with the ‘down’ button provides a list of wellness, navigational, and quality-of-life widgets. Outdoor-focused widgets range from the weather, sunrise and sunset times, and a compass shortcut to your sleep tracking information. Wellness stuff includes your last completed workout, sleep, Body Battery and your Training Readiness score. As a watch tailored to the great outdoors, all the functionalities you expect can be found here and the list can be customized as usual to suit your needs. Climbing a mountain? Stick the altimeter at the top. A keen marathon runner? Choose the ‘Race Calendar’ widget.

It’s fun, intuitive and acts like the watchOS 11 widget stack, but less flashy. I found most of the usual Garmin stuff there, but some premium features like Endurance Score and Hill Score were missing. They would have been nice to have. As previously mentioned, there’s no topographical maps functionality either, just basic directional guidance, but there have never been maps on an Instinct watch, and most of the time directions are all you need. You can, however, still retrace your steps with the ‘TracBack’ feature, along with a slew of other navigational tools.

Hardware-wise, the new torch is very useful: it comes in four intensities and a less dazzling red option, just like the torch on the Garmin Fenix 8. I’ve already used the red light on an evening run and the white light to help me stumble my way to the bathroom at six am. In the morning, you’ll get a daily digest, Garmin’s ‘Morning Report’ detailing information on your sleep, the weather, your Training Readiness, and a motivational message. Garmin’s been doing this for a while and it’s refined the feature over the last couple of years. Its long battery life means you won’t shy away from wearing it to bed.

• Features score: 4.5/5

Garmin Instinct 3: Performance

• Superb battery life
• Navigational features fine
• Comparable to other Garmins

The bottom line is, if you’ve used another Garmin, this will all be very familiar. There’s no reinventing the wheel here, and as I’m trying to review the watch in a vacuum, I can’t really dock points for lack of innovation. It’s a superb running and walking watch, with lots of features at a reasonable price point.

Heart rate tracking doesn’t betray any major inaccuracies compared to pace and cadence of runs and walks, even though it uses the older sensor. It showed comparable statistics to the Apple Watch Ultra 2. it’s got a serviceable strength training mode most people won’t bother with, and will even track other outdoor disciplines such as surfs with GPS information, including travel speed and estimated number of waves caught.

All of Garmin’s outdoor-focused features are clear and present here, and the AMOLED screen offers a similar experience to the Garmin Forerunner 265 and 965: intuitive to navigate with the buttons, even with gloves on, and the widget list is easy to customize. I tried TracBack on one long run, and that worked fine even without maps, helping me retrace my steps easily enough. Even the screens viewed during exercise are customizable, not just the home menu of widgets.

The battery life is really good, far outperforming many other running watches in its price bracket, with the exception of Coros. The AMOLED 45mm Instinct doesn’t reach Coros’ 24-day heights, but its listed 18-day battery life was accurate based on my testing period. I occasionally used the torch indoors and outdoors at night and found it bright enough for my needs, but not as bright as the Epix Pro (Gen 2)’s more powerful, similar torch.

How I tested the Garmin Instinct 3

I wore the Garmin Instinct 3 during strength training workouts, boxing workouts, runs and even went surfing with it. I tested its TracBack features on a long out-and-back run, checked its heart rate readings against an Apple Watch Ultra, and ran the battery down over 16 days of use.

Garmin Enduro 3: One-minute review

The launch of the Garmin Enduro 3 was undeniably overshadowed by the company's decision to unveil the Garmin Fenix 8 alongside it. The new Fenix brought the AMOLED Epix and Fenix under one name but at a premium price.

The Enduro line puts battery first, all while offering most of the features from the Fenix series. The Enduro 2 did that more than the original Enduro and for the Enduro 3, the remit remains the same.

It promises over a month of battery life on a single charge, with new solar charging display technology to push things even further than a month. Garmin has included its new software, which brings changes to features like mapping and navigation with a new dynamic round-trip routing feature that will let you adjust your route on the fly. Those software changes make using the Enduro 3 feel more like using a smartwatch. It also adds in a new optical heart rate sensor, which brings temperature and ECG-style tracking into the mix as well as offering a boost in heart rate monitoring accuracy.

That’s all while giving you everything great we got on the Enduro 2, for less money than its predecessor and the new Fenix 8. It’s still a very expensive watch and is going to be too pricey for many. You get what you pay for here and if rich sports tracking, training analysis, the best mapping features, and huge battery life are things you want more than anything, that’s what the Enduro 3 will give you.

The Garmin Fenix 8 is deservedly one of the best Garmin watches. But, if you can live without an AMOLED screen and some additional voice-based smartwatch features, the Enduro 3 is great too and will go longer than the Fenix too.

Garmin Enduro 3: Specifications

Garmin Enduro 3: Price and availability

• Price for Enduro 3 is $899/£769/AU£1,549
• Prices for 43mm Fenix 8 start at $999 / £949 / AU$1,699

The Garmin Enduro 3, unlike the Fenix 8, comes in just one size option and costs $899/£769/AU£1,549. In contrast, Garmin’s Fenix 8 series starts at $999 / £949 / AU$1,699, so is something of a step in price even if you opt for the cheapest model.

When the Garmin Enduro 2 launched it sat at $1,099/£929/AU 1,749, so that’s somewhat surprisingly a drop in price for the latest Enduro, which isn’t typically the case when a new model in a Garmin watch series arrives.

Put that up against other outdoor watches outside of Garmin’s own, it’s pricier than the Polar Grit X 2 Pro and the Suunto Vertical. You can also include smartwatches like the Apple Watch Ultra 2 and the Samsung Galaxy Watch Ultra as cheaper alternatives to the Enduro 3 that, unlike the Enduro, pack in AMOLED displays.

• Value score: 4/5

Garmin Enduro 3: Design

• Comes with a nylon strap
• Less prominent Power Sapphire lens
• Lacks Fenix 8 leak-proof buttons

The Enduro 3 sticks very closely to the design of the Enduro 2, including a slightly thicker 51mm, all-black polymer case, titanium bezel, and a very comfy black nylon strap. The differences lie with the same-sized, 1.4-inch, 280x280 resolution touchscreen. While you don’t get a colorful AMOLED one like the Fenix 8, you do get a display that’s a good size and does a much nicer job of masking its solar charging display abilities.

Garmin is using an improved version of its Power Sapphire lens, which once again has the ability to harvest sunlight to give you more in-between charges. Along with being able to perform that task in a more efficient manner, the red ring on the Enduro 2 to indicate those onboard solar powers is now gone, leaving a much clearer and overall nicer transflective display to look at. It is still a breeze to look at in much brighter outdoor light and marks an upgrade both aesthetically as well as in how effectively the Enduro can now harvest that solar power.

Outside of the changes in the display department, this is a watch that feels very Garmin. You’ve got a pretty standard array of physical buttons that aren’t the leak-proof kind included on the Fenix 8. It’s suitable for swimming up to 100 meters depth and uses Garmin’s go-to proprietary charging cable. If you liked the LED flashlight on the Enduro 2, there’s now a brighter one on the Enduro 3. The strap included is a quick-fit kind, which makes it easier to swap in an official or unofficial band. The nylon one included though makes this watch, which will still no doubt be a hulking one for some, a little more manageable and comfortable to wear 24/7.

• Design score: 4/5

Garmin Enduro 3: Features

• New user interface
• Richer mapping and navigation features
• Gen 5 Elevate heart rate sensor

The headline news on the Enduro 3 is that the software it’s running on is all new. You won’t get it on the Enduro 2, but you will find it on the Fenix 8 and future Garmin watches. That new software is really centered around bringing sports watch and smartwatch features closer together and making the Enduro 3’s mapping and navigation modes easier to do on the move. Those new mapping and navigation features are led by a new dynamic round-trip routing mode that will automatically adjust your route in real time for whatever reason you need to adapt your route.

The core sports you can pick from stick largely to the same ones as the Enduro 2 with a bigger emphasis on strength training and letting you follow plans to factor that work into your training schedule. These plans range from 4-6 weeks and aren’t just for people who choose weights over cardio. This is about helping runners, cyclists, and swimmers to incorporate more strength training to reap the benefits of it in those sports.

On the hardware front, Garmin has upgraded the Enduro’s optical heart rate sensor to its latest Gen 5 one, which features inside of the Fenix 7 Pro, Epix Pro, and the Fenix 8. Along with promising the best heart rate accuracy that Garmin has to offer, it also unlocks the ability to take ECG-style measurements and temperature readings from the wrist. Those might not necessarily be the biggest reasons you’d be looking at picking an Enduro 3, but for those wanting a better mix of general wellness and sports tracking, the Enduro 3 offers a little more on that front.

In terms of other software features, this is a watch that arms you with an LED flashlight, offers training insights like altitude and heat acclimation, and gives you daily morning reports to tell you if you’ve slept well and whether you’re in good shape to train. While it lacks the new voice features included on the Fenix 8, does still let you pay your way, download apps and customize watch faces, and download and store music from services like Spotify.

• Features score: 4.5/5

Garmin Enduro 3: Performance

• Impressive battery life once again
• Slightly improved HR performance
• Richer mapping support

The Enduro 3 mirrors a lot of what we got in the Enduro 2 and that’s not necessarily a bad thing. That’s never more true of the Enduro 3’s standout quality, and that’s the battery life. Whether you’re using it like a smartwatch or using it with its best GPS accuracy mode, you won’t be reaching for a charger for weeks. I managed to get just shy of a month from it and that was while mainly using it with its most accurate GPS mode. I used it for outdoor runs, indoor workouts, pool, and open water swims, and the battery performance really impressed

You do get that added reserve of solar charging, which boosts battery performance considerably. 36 days of battery in smartwatch mode becomes 90 days. Getting to that number requires regular exposure to sunlight to top up those reserves. I could see from spending just a couple of hours in strong sunlight how that battery is noticeably topped up too.

The multi-band GPS support is as good as it is on other Garmin watches like the Fenix 8 and the Forerunner 965. If you’re looking for accurate GPS support in more challenging conditions, the Enduro 3 is fit for the job. Moving to Garmin’s latest Gen 5 Elevate optical heart rate monitor does see a small improvement in the reliability of heart rate tracking but as I do find with bigger Garmin watches, it struggles at high intensity such as when I used the Enduro 3 for harder running sessions.

While the first Enduro missed out on Garmin’s great mapping support, that changed for the Enduro 2 and the Enduro 3 gets the best Garmin has to offer on that front now. That includes adding new ways to toggle and change map views and also features Garmin’s new dynamic round-trip routing, which does take a few minutes to adjust routes before you can be on your way again.

Garmin’s efforts to make strength training feel more a part of the tracking experience is a valiant attempt. Especially when elements like rep counting aren’t impeccable on sports watches in general. Adding plans that are presented like Garmin’s running ones makes it easy to follow plans, which is going to be welcomed by those that typically neglect it.

How I tested

I wore the Garmin Enduro 3 for over a month to completely drain the battery, tracking activities like running, swimming, and using mapping and navigation features. I made use of smartwatch features like notifications and music support and wore it alongside the Garmin Fenix 8 to compare GPS accuracy. I also used a heart rate monitor chest strap to gauge the performance of heart rate tracking for both steady-paced and high-intensity workouts.
