Today's best outdoor watches are amazing. Of all the technology you can seek out, outdoor watches (arguably) pack in the most potent sensors and tools for modern life into a tiny package. They're more precise than a simple smartphone, and with far better battery life. Meanwhile, other options are all-but indestructible and simply tell the time – while looking awesome of course. 

While screen real estate is limited, adventure watch manufacturers have taken many tips from smartwatches, and indeed many outdoor watches do double duty as smartwatches, as well as GPS units, running coaches, training aids and music players, to name but a few functions.   

We think the best outdoor watch right now is the brand new Suunto 9 Peak. It combines most of the firepower of the former flagship Suunto 9 Baro into a tiny package, but with no battery life penalty... at least on paper. That said, the competition – in the shape of the Garmin Fenix 6 Pro Solar – takes a lot of beating too, packing similar abilities into a comfortably-wrist-mounted package. 

However, these are both all-rounders, so we've picked out a few specialist watches for different outdoor pursuits to balance the books. Read on for our ranking of the best outdoor watches right now – whatever you're into.

 The best outdoor watch 2021

1. Suunto 9 Peak

The best outdoor watch for pretty much everything

Build: Stainless steel bezel
Weight: 62g
Water resistance: 100m
Battery: 14 days time only; GPS: 25h / 50h / 120h / 170h
Reasons to buy
+Tiny and ultralight +Super-slim+Packs in serious functionality 
Reasons to avoid
- Fewer Navigation chops 

The Suunto 9 Peak is in many ways a whole new generation of outdoor smartwatch, marrying much of the firepower of the previous flagship - the Suunto 9 Baro - with much reduced size and weight. That’s not to say there’s no innovation here, with blood O2 levels added to an extensive mix of fitness monitoring and stats that can be shared among the big-name partner apps to give you flexibility and a full picture, no matter your preferences. 

As usual the list goes on and on, vo2 max, heart rate training, coaching, recovery. Navigation is the minor deviation – although the impressive array of GPS, GLONASS, GALILEO, QZSS, BEIDOU satellite constellations is present and correct, there are a couple of gaps compared to the Suunto Baro 9, most notably bearing navigation (for a full comparison, head to our Suunto 9 Peak vs Suunto 9 Baro faceoff). 

However, it’s a blistering list of useful training tools and an entire outdoor toolkit in a tiny watch that you’ll barely notice wearing, and won’t need to charge much either. Top marks.

2. Garmin Fenix 6X Pro Solar

The best outdoor watch for all-round doing

Build: Titanium bezel
Weight: 82g
Water resistance: 10 ATM
Battery: 21 days +3 days in smartwatch mode; GPS: up to 60 hours +6 hours
Reasons to buy
+Available in solar-powered model+Tech for all situations+Super rugged
Reasons to avoid
-Bewildering range of options-Might be too heavy for some

Garmin has been at the outdoor smartwatch game for a while now, and its latest effort is, well, cheating. We say this because the range of versions of the Fenix 6 is vast – there are 3 case size options, optional music, maps and wifi, sapphire glass and even solar options. It’s more like spec-ing a new car than a watch. In short, the base Fenix 6 models don’t include maps, wifi or music, the Pro models do, and add in extras on top (see out Garmin Fenix 6 Pro review for more on this).

However, once you’ve surmounted that specification hurdle, the Fenix 6 Pro Solar is a beast of a watch, offering so much functionality that you’ll need a week off just to work it all out. From preloaded ski maps to fitness coaching, golf course maps to underwater wrist-based HR tracking, this watch has it all. 

Particularly strong for outdoors folk is the solar charging function, which will string out battery life to a maximum of 24 days, as is the extensive navigation package that will get you out of trouble with ease - if you have worked out how to set them up. GPS, GLONASS and Galileo satellite systems are all supported, and features like ClimbPro (ascent rate monitor), round trip routing and turn by turn navigation will make it very hard to get lost. If you’re looking for the biggest, baddest and spendiest outdoor watch, this is it. Head to our Garmin Fenix 6X Pro Solar review to find out more.

Best outdoor watch: Suunto 7

3. Suunto 7

A great everyday outdoors watch

Build: Bezel: Stainless Steel
Weight: 70g
Water resistance: 50m
Battery: Up to 12 hours in GPS tracking mode or up to 48 hours in daily use
Reasons to buy
+Feature rich +Beautiful OLED screen +Everyday smartwatch
Reasons to avoid
-Hard on batteries

The Suunto 7 takes a bit of a new tack compared to previous outdoor watches, seeking to blend the everyday usability of a smartwatch with the powerful mapping and tracking of a 'real' outdoor watch (The Suunto 7 supports GPS, Glonass and Galileo). The tricky bit here is to keep a decent battery life, which the Suunto 7 does, at 12 hours in GPS mode and 48 hours in smartwatch mode. 

The benefits are pretty hefty: you get smartwatch apps aplenty, Google Fit, Google Assistant, and notifications as well as offline outdoor maps and more than 70 sports modes. The result is a watch that'll keep pace with your working week, track your daily training routine, and then be ready for big weekend expeditions – all while looking pretty stylish. A compelling mix. Find out more in our Suunto 7 review.

best outdoor watch: Amazfit T-Rex Pro

4. Amazfit T-Rex Pro

The best budget outdoor watch

Build: Polycarbonate
Weight: 59.4g
Water resistance: 10 ATM
Battery : Up to 18 days/heavy use 9 days/continuous GPS 40 hours
Reasons to buy
+Impressive sensor array+Very wallet-friendly
Reasons to avoid
-Basic functionality-Limited data sharing

The 2021 Amazfit T-Rex model has three big headlines to shout about – it’s very keenly priced, it has more sensors than the Mars Perseverance Rover, and it’s pretty much siloed. The latter is the big pitfall here, as sharing your own fitness data with other apps isn’t going to happen, so you’re stuck with the relatively basic training tools and incentives on offer here. 

Sensors-wise though, we have a kitchen sink of goodies, astonishing at this price point, featuring a quad system GPS (GPS, GLONASS, Beidou, Galileo), wrist heart rate with zones and alerts, blood-oxygen saturation, recovery times, sleep monitoring and smartwatch-style notifications when paired to the companion app.   

Design wise the Amazfit T-Rex Pro is on the dated side, and the strap is very much of a 90s vintage, but the overall package is worth considering if you’re looking for excellent tech at a very wallet-friendly price point. Well worth considering at the price point.

best outdoor watch: Suunto baro titanium

5. Suunto 9 Baro Titanium

A tech-packed mountain fitness performer

Build: Titanium bezel with glass fiber polyamide case and sapphire glass
Weight: 62g
Water resistance: 100m
Battery: 14 days, 25-120 hours GPS mode
Reasons to buy
+Endless features for every occasion+Training tools 
Reasons to avoid
-Fiddly to get the best from-No music or payments

When you want fitness tracking whenever, wherever, then the Suunto 9 Baro has a lot to say for itself. The ‘baro’ in the name refers to an additional barometer sensor over the stock model, which not only provides weather information, but also makes that the GPS tracking much more accurate on long ascents. The 'titanium' part of the name means you've got an ultralight Titanium bezel that shaves a few grams off the stock Stainless Steel version

With 80 sports to choose from there’s no limit to the use you’ll get out of the Suunto, and the ability to sync and upload routes and PBs to the companion app is handy for comparisons and sharing with friends. Wrist heart rate monitoring is built in, as are a myriad of fitness stats, and there’s even sleep tracking too. This watch has all the bells and whistles you could want for, and even has a decent battery life with them all switched on. Head to our Suunto 9 Baro Titanium GPS watch review to find out more about the top-end version of this watch.

6. Casio G-Shock British Army Mudmaster

The best outdoor watch for the tacti-cool

Build: Bezel: triple-layered carbon-insert bezel
Weight: 92g
Water resistance: 20 bars / 200M
Battery: Approx 2 years on CR2025
Reasons to buy
+MoD approved+Super rugged+Long battery life
Reasons to avoid

The toughest watches just got tougher with this partnership between the Ministry of Defence and G-SHOCK, designed specifically for missions in the harshest land environments on the planet. Enormously robust and durable with a massive battery life, the Mudmaster also features a stealth-black dial for operational reasons. 

There's tech under the hood too, with Bluetooth Low Energy adding special app functions including a location indicator, mission log memory, location memory, sunrise and sunset data and calories burned. Onboard the watch you'll find sensors including compass, thermometer, altimeter/barometer, and step tracker. If it's good enough for the army...

Best outdoor watches: Tissot T-Touch Solar Expert

7. Tissot T-Touch Solar Expert

High-end, high altitude expedition wristwear

Build: Titanium case and strap
Water resistance: 10 bar
Reasons to buy
+Swiss quartz movement+Solid feature set +Almost unlimited battery life
Reasons to avoid
-No GPS or smart features

The snappily-named Tissot T-Touch Solar Expert ticks a lot of expedition boxes. Robustly built from titanium, the touchscreen face also conceals a solar panel, so there’s no danger of a dead battery in the Karakoram. The feature set is strong too, with 25 features including weather forecasting, altimeter, second time zone and a compass built in. Although the latter is probably best saved for real emergencies, the barometer/altimeter function could come in very handy for acclimatising hikes. With a range of strap materials on offer to suit all preferences, this is stylish enough for town, but also tough enough for those mountain excursions too.

8. Garmin Quatix 6X Solar

The best outdoor watch for marine activities

Build: Titanium
Water resistance: 100M
Reasons to buy
+Ridiculous battery life+Brilliant navigation tools+Built-in boat autopilot
Reasons to avoid
-Quite complex-Overkill if you're not taking to water

If you're a water-lover, the best outdoor watch for you is the Garmin Quatix 6X Solar.  This watch takes the land-based tools and tech found in our top ranking 6X range, and adds a whole bunch more geared towards more watery pursuits. There are plenty of features aimed at boat owners, SUP riders, windsurfers, kayakers and more. Additions include wrist-based autopilot control, dedicated marine mapping and bespoke sailing tools. You'll also get Garmin's solar-boosted battery, which means this watch will run and run... and run. While it's absolutely excellent for marine sports, it's probably unnecessarily complex for land-lovers. Head to our full Garmin Quatix 6X Solar review for more info.

Best outdoor watches: Victorinox I.N.O.X

9. Victorinox I.N.O.X

Understated survival special

Build: Anti-reflective sapphire crystal, screw down crown
Water resistance: 20 ATM/200M/660 FT
Reasons to buy
+Astonishingly robust+Unassuming looks 
Reasons to avoid
-No GPS here-Low tech only 

Sometimes you want simplicity, you crave form, function but no distractions, and this is when the Victorinox I.N.O.X makes complete sense. A simple exterior and basic quartz movement provide little bling or technical wizardry, but the case claims to be the only Swiss watch to withstand 130 extreme endurance homologation tests, which is no idle boast. The strap is woven from survival favourite paracord, high breaking strain cord that can be used to construct all manner of useful shelter-related items, and also included is a removable compass bumper for protection against scratches, and easier navigation. Survivalist simplicity doesn’t come looking better than this.

best adventure watch: Casio Pro Trek WSD-F30

10. Casio Pro Trek WSD-F30

The best outdoor watch for everyday wear

Build: Military Tested MIL-STD-810G 1.2 inch Display OLED and Dual Layer Display Monochrome LCD
Weight: 83g
Water resistance: 50 metres
Reasons to buy
+Wear OS Smartwatch +Decent battery life
Reasons to avoid
-Large for a watch, small for a GPS

The Casio Pro Trek WSD-F30 is a standard digital wristwatch with (admittedly barely) hidden GPS and smartwatch trickery designed for the tech savvy outdoorsman. The styling might be somewhat polarising, but the tools are all present and correct. 

Casio has pulled off a clever trick here, by integrating a Wear OS smartwatch with a ‘standard’ digital watch. The core of this trick is the dual layer screen, which enormously extends battery life by displaying normal time/date/etc information on the power saving monochrome, then firing up the thirsty OLED and Wear OS for more complex tasks. 

There’s a host of sensors and transmitters here, GPS, GLONASS & Michibiki, Wifi, Bluetooth, Compass, Altimeter and Barometer as well as the power of Google Play apps such as Viewranger, Runtastic, Spotify and Strava, so most outdoor requirements can be taken care of with the right app - something that less open platforms can struggle with. The charger can be fiddly however, and it is a chunky watch for everyday wear, so it’s worth checking out in person first. For more info, check out our Casio Pro Trek WSD-F30 review.

Best outdoor watches: Elliot Brown Mountain Rescue Canford

11. Elliot Brown Canford: Mountain Rescue edition

The best outdoor watch for blending style with charity

Build: Bezel: Steel
Water resistance: 20ATM/200M
Battery: 3 years, with EOL indication
Reasons to buy
+Donate to MRT+Very robust+Style for all occasions
Reasons to avoid
-No bells or whistles

Sometimes outdoor watches just need to tell the time and look good, and the Elliot Brown Canford: Mountain Rescue edition does exactly that. Buying one also donates £36 to Mountain Rescue England & Wales, and there's a very subtle ghosted matt on gloss MREW logo in the bottom half of the dial as a nod in that direction.

A ludicrously rugged case with triple sealed 6mm knurled crowns will laugh off anything short of a tank, and simple but clean green SuperLuminova coated indices and hands make this a pretty idiotproof time telling machine. There is a date marker, and two straps – a practical EPDM black rubber strap for weekdays in the office and a custom made black ballistic nylon webbing strap for hitting the hills at the weekend. Sometimes simplicity is bliss. 

Best outdoor watches: Shearwater Teric

12. Shearwater Teric

The best looking dive watch on the market

Build: Stainless steel bezel with sapphire lens
Water resistance: 200m
Battery: 30hrs dive mode, 50 hrs watch mode
Reasons to buy
+Stunning design+Compact 
Reasons to avoid
-Expensive-Low, smartwatch-style battery life

The Shearwater Teric is a little bit special in the world of dive watches, and has already forced bigger brands to follow suit. Essentially it’s a diving smartwatch, which might sound obvious, but when you’re 50m deep on trimix a crash and reboot to factory settings could be somewhat harrowing. Above water you’ve got a sizeable AMOLED screen, chunky stainless bezel and sapphire lens, with a variety of different watch faces and strap colours to choose from. Underwater you have wireless tank pressure integration, configurable display, as well as full trimix, nitrox, air and gauge settings. 

In short, the Teric is a highly potent dive computer, as well as being an everyday watch. Unfortunately, the only question right now is whether you can find one to buy, as they’re in very short supply.

 How to buy the best best outdoor watch for you 

There’s a huge range of outdoor watches on the market, so before you dive in you’ll want to be clear from the outset just how much technology you really need. Too much and you’ll be out of battery within a couple of days, too little and your training program will suffer.

For big expedition use, smartwatches and intensive GPS trackers are just too power-hungry, and you’ll want something solar powered or just very simple to keep working in all conditions.

If you’re set on a tracking model, be clear whether you’ll just be tracking your progress for training, or using it as a navigational aid, as the two don’t always go hand in hand.

Models that use GPS and other sensors (such as a barometer) often have better accuracy, but this may chew battery faster. On the bright side, the newest models tend to have a series of settings, so you can balance accuracy with battery life. 

Overall – a few incredible all-rounders aside – the best outdoor watch for you will depend on what you want to be doing. Choose wisely, and get out there!
