Choosing Your Ultimate Swimming Watch
Picking the right watch for your swimming sessions can feel a bit like trying to swim upstream sometimes. There are heaps of options out there, all promising the moon and stars, but what do you actually need? Let’s break it down.
Key Features for Pool and Open Water
When you’re looking at watches, think about where you’ll be doing most of your swimming. If it’s mostly in the pool, you’ll want something that’s good at counting laps, recognising your strokes, and maybe even timing your rests. For open water, GPS becomes a big deal so you can track your distance and route. Most decent swimming watches will give you a good mix of both, but it’s worth checking the specifics.
- Lap Counting: Accurately counts each length you swim.
- Stroke Recognition: Identifies different swimming styles like freestyle, backstroke, etc.
- GPS Tracking: Maps your route and distance in open water.
- Heart Rate Monitoring: Tracks your heart rate, even underwater.
Understanding Waterproof Ratings
This is a big one. You don’t want your watch giving up the ghost halfway through a swim. Watches have different ratings, usually measured in ATM (atmospheres). A 5 ATM rating is generally okay for splashes and showers, but for actual swimming, you’ll want at least 10 ATM. This means it can handle being submerged for longer periods and even a bit of diving into the water. Some higher-end models go up to 20 ATM, which is pretty tough.
| Rating | Suitable For |
|---|---|
| 5 ATM | Showers, splashes |
| 10 ATM | Swimming, diving into water |
| 20 ATM | Swimming, diving, high impact water sports |
Always check the manufacturer’s advice, especially regarding saltwater use. Some brands recommend a good rinse in fresh water after a dip in the ocean.
Essential Metrics for Swimmers
Beyond just counting laps, what data will actually help you improve? Things like SWOLF scores (which measure swimming efficiency by combining strokes per length and time per length) are super useful. You’ll also want to see your pace per 100 metres, total distance, and stroke rate. If you’re serious about getting faster or fitter, these numbers are your best mates. The Apple Watch Ultra 2 is known for its robust tracking capabilities, making it a solid choice for data-driven swimmers.

Advanced Tracking and Data Analysis
When you’re serious about improving your swimming, the data your watch collects becomes super important. It’s not just about counting laps anymore; it’s about understanding your technique and how to get faster.
SWOLF Scores and Stroke Recognition
SWOLF, a portmanteau of ‘swim’ and ‘golf’, is a metric that helps gauge your swimming efficiency. It’s calculated by adding the number of strokes it takes to complete a length to the time it takes for that length. A lower SWOLF score generally means a more efficient swim. Most modern swim watches can automatically detect your stroke type – freestyle, backstroke, breaststroke, and butterfly – and calculate your SWOLF score for each length. This helps you see which strokes are most efficient for you.
Open Water GPS Accuracy
For those who prefer the open water, GPS accuracy is a big deal. You want to know your distance, pace, and route are being tracked reliably, even without the lane lines of a pool. Watches with multi-band GNSS support, like the Garmin Fenix 8, can connect to more satellite systems simultaneously, giving you a much more precise track, especially in areas with tall buildings or dense tree cover. This means you can trust your distance and pace data when swimming in lakes or the ocean. The Garmin Swim 2 is also known for its solid GPS performance in open water.
Biometric Data Underwater
Getting biometric data like heart rate while you’re actually swimming used to be a bit hit-and-miss. However, newer watches are getting much better at this. They use optical heart rate sensors that are designed to work even when submerged. This allows you to monitor your exertion levels in real-time, helping you train in the right heart rate zones. Some advanced watches can even track blood oxygen saturation (SpO2) underwater, though this is still a developing feature.
Here’s a quick look at what some watches might track:
- Stroke Count: How many strokes per length.
- Stroke Rate: Strokes per minute.
- SWOLF Score: Strokes + time per length.
- Pace: Speed per 100 metres/yards.
- Distance: Total distance covered.
- Heart Rate: Beats per minute while swimming.
Understanding these metrics helps you pinpoint areas for improvement. Don’t just look at the numbers; try to connect them to how you felt during the swim. Was a high stroke count on a particular length because you were tired, or because your technique faltered?
Durability and Display Considerations
When you’re splashing around, whether it’s in the pool or out in the big blue, the watch you’re wearing needs to be tough. It’s not just about looking good; it’s about being able to handle the knocks and the water. Plus, you’ve got to be able to see what it’s telling you, even when the sun’s glaring off the water.
Screen Clarity Underwater
This is a big one. You’re mid-lap, you want to check your pace or stroke count, and the screen is just a blurry mess. Not ideal. Most modern swim watches use either AMOLED or MIP (Memory-in-Pixel) displays. AMOLED screens are bright and vibrant, like your phone, but they can struggle a bit in direct sunlight. MIP screens, on the other hand, use ambient light, so they actually get clearer the brighter it is outside. They’re also way better on battery life, which is always a win.
- AMOLED: Great for low light, vibrant colours, but can be tricky in bright sun.
- MIP: Excellent in direct sunlight, uses less power, but colours aren’t as punchy.
- Touchscreen vs. Buttons: Some watches rely solely on touch, which can be a pain with wet fingers. Others have physical buttons, which are usually more reliable when you’re actually swimming.
Choosing the right screen type really comes down to where you’ll be doing most of your swimming. If it’s mostly indoors or you don’t mind a quick tap to wake the screen, AMOLED is fine. But for open water where the sun is king, MIP is often the way to go.
Robust Build Quality
No one wants a watch that falls apart after a few months of chlorine or saltwater. You need something built to last. Look for watches with tough screen materials like sapphire glass, which is seriously scratch-resistant. Cheaper mineral glass will do the job, but it’ll pick up scratches a lot faster. The casing itself should feel solid, too – think reinforced polymer or even titanium for the really high-end stuff. And don’t forget the strap; silicone or a good quality textile band will be more comfortable and durable than cheap plastic.
Battery Life for Extended Swims
This is where things can get a bit hairy. If you’re doing long open water swims or multi-day events, you don’t want your watch dying halfway through. MIP screens are generally much better for battery life than AMOLED ones, especially if you have the screen set to always-on. Some watches can last weeks on a single charge in basic watch mode, but once you start using GPS and tracking your swim, that number drops significantly. It’s worth checking out reviews specifically for battery performance during GPS activities, as manufacturers’ claims can sometimes be a bit optimistic.
- GPS Usage: Constantly using GPS drains the battery much faster.
- Screen Settings: An always-on display, especially AMOLED, uses more power.
- Activity Type: Longer swims with more data points will use more battery than shorter, simpler sessions.
Beyond the Pool: Multisport Capabilities
So, you’ve got your swimming watch sorted, and you’re smashing laps in the pool or tackling open water. But what if your aquatic adventures extend beyond just swimming? Many of today’s top fitness watches aren’t just for the pool; they’re built for a whole range of activities, making them super versatile.
Triathlon-Ready Features
If you’re into triathlons, your watch needs to handle more than just swimming. Look for watches that can track cycling and running too, switching between disciplines automatically or with a quick button press. This means you can get a complete picture of your race or training session without fumbling with different devices. Some watches even offer specific triathlon modes that combine all three sports into one activity profile.
Key triathlon features to look for:
- Transition tracking: Automatically records time spent in the bike-to-run transition.
- Multisport modes: Seamlessly switch between swim, bike, and run activities.
- Advanced running and cycling metrics: Pace, distance, power, cadence, and more.
- Heart rate variability (HRV): Helps gauge your body’s recovery and readiness for training.
Dive Computer Functionality
For those who enjoy exploring beneath the waves, some high-end sports watches double as basic dive computers. These can track your depth, dive time, ascent rate, and even provide decompression stop information. While they won’t replace a dedicated dive computer for serious technical diving, they’re handy for recreational snorkelling or shallow dives. It’s important to check the specific depth rating and dive features before relying on a watch for any underwater exploration.
Versatility for Other Water Sports
Beyond triathlons and diving, many watches are great for other water-based activities. Think paddleboarding, kayaking, or even surfing. They can track distance, speed, stroke rate (for paddling sports), and provide GPS mapping of your route. The robust waterproofing and clear displays we talked about earlier are a big plus here, too. For example, the Fitbit Charge 6 is noted for its water resistance and automatic swim tracking, hinting at its broader aquatic capabilities.
It’s pretty neat how one device can keep up with so many different ways to get wet, isn’t it? You’re not just buying a swim watch; you’re often getting a full-blown adventure companion.
Innovative Swim Tracking Solutions
It’s not just about what’s on your wrist anymore. The world of swim tracking is getting pretty clever, moving beyond just watches to offer new ways to get data right where you need it. Think about it – having your stats appear right in front of your eyes as you swim? That’s a game-changer for some swimmers.
FORM Swim Goggles: Heads-Up Display
These smart goggles are a bit of a standout. Instead of glancing at your wrist, FORM goggles project your key swim metrics directly onto the lens. You can see your splits, stroke rate, distance, and even heart rate (if you’re using a compatible monitor) without breaking your stroke. It’s pretty neat, especially if you find yourself distracted by looking at a watch or prefer a more streamlined feel in the water. The real-time feedback is designed to help you focus on your technique and pacing without missing a beat.
Smart Features for Lap Swimmers
Beyond the goggles, there’s a growing trend of apps and devices that make tracking laps and workouts simpler. Some systems can automatically detect your stroke and count laps, taking the guesswork out of it. This is brilliant for swimmers who just want to focus on their effort and not worry about manually logging every length. Plus, many of these apps sync with popular watches, giving you a more detailed breakdown of your performance after your swim.
Comfort and Fit for Long Sessions
When you’re spending a lot of time in the pool, comfort is key. The design of any tracking device matters. Goggles, for instance, need to fit snugly without leaking or causing discomfort over extended periods. Similarly, watches should feel secure but not restrictive. The best solutions are those that you almost forget you’re wearing, allowing you to concentrate purely on your swimming. It’s about finding a tool that supports your training, rather than getting in the way.
So, Which Swim Watch is Right for You?
Alright, so we’ve looked at a bunch of these swimming watches. It’s pretty clear that whether you’re just starting out with laps or training for a big open water event, having the right gear on your wrist makes a difference. We saw some serious contenders like the Garmin Fenix 8, which seems to do it all, and the Apple Watch Ultra 2, a solid choice if you’re already in that ecosystem. Even more budget-friendly options like the Coros Pace 3 offer a lot for the money. Think about what you really need – do you want loads of data, or just the basics? How important is battery life? Answering those questions will help you pick the watch that’ll actually get used and help you smash your swimming goals. Happy swimming!
