The 8 Best Smartwatches for Swimming

Swimming demands more from a smartwatch than almost any other activity. Your device needs to survive not just splashes but full submersion, lap after lap, in chlorinated pools or open water.

Beyond waterproofing, the best smartwatches for swimming track stroke count, lap distance, SWOLF scores, and heart rate without skipping a beat.

Whether you are a competitive swimmer chasing personal records or a casual fitness enthusiast who wants pool sessions counted alongside your runs, choosing the right water-ready wearable makes a real difference.

You can explore the broader fitness trackers category for alternatives if a dedicated sports watch is more than you need.

This guide covers eight water-ready smartwatches ranging from budget-friendly daily wearables to rugged outdoor sport watches built for serious aquatic training.

REMOVU researchers evaluated each model through a synthesis of published specifications, expert review consensus, and verified buyer feedback, then scored every pick on our 0 to 10 REMOVU Score scale.

The result is a shortlist you can trust regardless of your budget or swim routine. Read on for our top picks, then dig into the buying guide below to find the model that fits your needs best.

Smartwatches for Swimming Buying Guide

Picking a swim-ready smartwatch involves more nuance than simply looking for a waterproof label. The sections below break down the criteria that matter most, from water resistance ratings to swim-tracking accuracy, so you can match a watch to your specific time in the water.

Water Resistance Rating: ATM, IP, and What They Actually Mean

Not all water resistance is created equal. The IP (Ingress Protection) scale rates dust and water resistance in two digits.

IP67 means the device can be submerged to one metre for up to 30 minutes, while IP68 extends that depth, typically to 1.5 metres or more, depending on the manufacturer’s specification.

For casual lap swimming in a standard pool, IP68 is the practical minimum you should accept.

ATM (atmospheres) ratings are common on dedicated sport watches. 5 ATM equates to roughly 50 metres of static water pressure resistance, which covers recreational swimming comfortably. Dive watches carry 10 ATM or higher.

For most pool and open-water swimmers who are not scuba diving, 5 ATM is the sweet spot.

Be aware that IP68 watches marketed for swimming may still carry manufacturer caveats about high-velocity water exposure, such as diving in or waterslide use, so always read the fine print.

Chlorine and salt water can degrade seals over time. Rinsing your watch with fresh water after every swim session is a simple habit that extends seal longevity considerably, regardless of the rating on the spec sheet.

If you also wear your watch during trail runs or bike rides, pairing it with a rugged fitness-focused smartwatch built for multi-sport use makes that maintenance even more worthwhile.

Swim Tracking Features: What the Watch Actually Records

A watch that can survive water is only half the equation. Dedicated swim modes separate entry-level waterproof wearables from genuine swim trackers.

The key metrics to look for are lap count, stroke type detection (freestyle, breaststroke, backstroke, butterfly), stroke rate, and SWOLF score, which combines strokes per length with time per length into a single efficiency number that serious swimmers use to benchmark progress.

Better swim modes also let you set your pool length manually, typically between 15 metres and 50 metres, so distance calculations stay accurate.

GPS is less relevant in a pool but becomes essential for open-water swimming, where the watch traces your actual route and total distance.

If open-water sessions are part of your routine, prioritise a model with built-in GPS rather than connected GPS that relies on your phone nearby.

Many budget smartwatches list swim as one of 100-plus sport modes but offer only basic time-in-water logging rather than true stroke analysis.

Reading verified buyer feedback from actual swimmers, not just generic wearable reviewers, is the most reliable way to separate real swim tracking from marketing checklist items.

Our broader roundup of smartwatches for men and smartwatches for women also surface models with strong swim credentials across different style preferences.

Heart Rate Monitoring Underwater

Optical heart rate sensors work by shining light through your skin and measuring the reflection change caused by blood flow. In water, this becomes significantly harder.

Movement artifacts from stroke mechanics, water movement over the sensor, and pressure changes can all introduce noise.

Budget optical sensors typically struggle to deliver accurate per-lap heart rate data during swimming, even when the watch is otherwise fine in the water.

Watches with improved sensor algorithms and tighter wrist bands fare considerably better. Wearing the watch slightly higher on your wrist, above the wrist bone rather than at the joint, reduces movement artifact and improves optical readings.

Expert reviewers consistently note that mid-range and premium devices calibrated specifically for aquatic use outperform generic fitness trackers in swim heart rate accuracy, even when the spec sheets look similar on paper.

SpO2 (blood oxygen) monitoring during swim workouts is a bonus rather than a baseline requirement for most swimmers, but it is increasingly standard even on more affordable models.

If cardiovascular training is your primary goal in the water, treat heart rate accuracy as a decisive factor rather than an assumed feature.

You might also compare notes with health-focused wearables for older adults, where cardiac monitoring accuracy receives heavy emphasis in reviews.

Display and Glanceability in the Water

Reading your watch mid-stroke is a real use case. AMOLED displays offer high contrast and vibrant colours that remain legible in bright outdoor light and indoor pool lighting alike.

LCD panels are more power-efficient but can wash out in direct sunlight. The display size matters too: a larger screen requires fewer interactions to see your current pace, lap count, and heart rate at a glance.

Always-on display modes are convenient for swimming because raising your wrist to wake the screen mid-lap is impractical. However, always-on modes reduce battery life noticeably.

Many swimmers prefer to configure a large, high-contrast watch face with always-on disabled, relying on a quick wrist raise at the wall instead.

Some watches also support touchscreen lockout during swimming to prevent accidental taps from water contact, which is a small but genuinely useful quality-of-life feature.

Battery Life and Charging Practicalities

Battery life claims on smartwatch spec sheets are notoriously optimistic. Manufacturers typically quote battery figures with GPS off, heart rate polling at low frequency, and the display off most of the time.

Real-world use, especially with GPS and continuous heart rate tracking active during a swim session, can cut rated battery life by 30 to 50 percent. Cross-reference the headline battery claim with user reports from verified buyers who describe their actual activity profiles.

For swimmers who train daily, a watch with genuine multi-day battery life between charges is far more convenient than a premium device that needs nightly charging. Missing a charge means missing swim data, which defeats the purpose.

Budget models in this guide prioritise battery longevity, while the feature-rich rugged option pushes performance metrics higher at the cost of more frequent charging.

The right trade-off depends on how seriously you track your data versus how much you value always having the watch ready to go.

If charging frequency is a dealbreaker, you might also consider models reviewed in our smartwatches under $200 roundup, where several picks balance capable swim features with respectable battery endurance at accessible price points.

Compatibility, App Ecosystem, and Everyday Wearability

A swimming smartwatch is still a daily wearable for most people. iOS and Android compatibility, notification handling, and the quality of the companion app affect how useful the watch is the other 23 hours of the day.

Some budget brands run proprietary apps with limited third-party integrations. If you rely on Strava, Apple Health, Google Fit, or a specific coaching platform, confirm compatibility before buying.

Built-in voice assistants such as Alexa add convenience for quick reminders and smart home control without pulling out your phone.

Bluetooth calling lets you answer calls from your wrist, which is useful during commutes or workouts where your phone is stowed away.

These lifestyle features do not affect swim performance but contribute meaningfully to whether you actually enjoy wearing the watch day to day, which in turn affects how consistent your tracking data becomes over time.

If you primarily use an iPhone, our guide to smartwatches for iPhone provides additional perspective on how well different Android-first brands handle iOS notification sync. Similarly, Android users can find more tailored picks in our smartwatches for Android guide.

Frequently Asked Questions

What Is the Difference Between IP68 and 5 ATM Water Resistance for Swimming?

IP68 certifies a device can be submerged at a manufacturer-specified depth, usually 1.5 metres, for up to 30 minutes under static conditions.

5 ATM rates resistance to 50 metres of water pressure, which is more appropriate for continuous swimming because it accounts for the dynamic pressure generated by strokes and kicks. For lap swimming, 5 ATM is the more meaningful rating.

IP68 can be sufficient for casual pool use but may carry caveats about high-velocity water exposure.

Can I Use a Smartwatch for Open-Water Swimming?

Yes, but built-in GPS is essential for open-water use. Without GPS, the watch cannot trace your route or calculate distance accurately in open water the way it does in a pool by counting laps.

Models with connected GPS that rely on your phone will not work reliably when your phone is left on shore.

Look for watches that specify built-in GPS rather than assisted or phone-based GPS if open-water swimming is a regular part of your training.

The Amazfit T-Rex 3 in this guide is the clearest example of a watch built for both pool and open-water environments.

Do Smartwatches Accurately Track Heart Rate While Swimming?

Accuracy varies significantly by model. Optical heart rate sensors face real challenges in water: stroke movement creates artifact, water pressure can shift the watch position, and chlorine can affect sensor performance over time.

Premium and mid-range sport watches with algorithms calibrated for aquatic use perform considerably better than generic budget trackers. Verified buyer feedback from regular swimmers is the most reliable indicator of real-world accuracy, more so than spec sheet claims.

Wearing the watch snugly and slightly above the wrist bone also improves readings across all models.

How Do I Choose Between a Budget and a Premium Swimming Smartwatch?

If you swim occasionally for fitness and primarily want your sessions counted alongside steps and sleep data, a budget model with IP68 or 5 ATM waterproofing and a basic swim mode covers your needs well.

If you train regularly, track stroke efficiency, rely on open-water GPS, or want accurate heart rate data throughout your swim, investing in a more capable mid-range or premium option pays off in data quality and long-term reliability.

Consider how central swimming is to your overall fitness routine, then match the watch’s capabilities to that role rather than paying for features you will never use.

Our fitness smartwatch guide covers how swim-focused picks stack up against cross-training and running-focused alternatives across all budgets.

Should I Be Concerned About Chlorine Damaging My Smartwatch?

Long-term chlorine exposure can degrade rubber seals, silicone straps, and adhesive bonds inside the watch casing, even on devices rated for swimming.

The practical mitigation is straightforward: rinse your watch under fresh water immediately after every pool session and allow it to dry before charging. Avoid charging a wet watch, as moisture in charging ports or contacts accelerates corrosion.

Most manufacturers recommend this practice explicitly in their care guidelines. Replacing the strap annually if you swim frequently is also a sensible precaution, and most watches in this guide use standard swap-out band systems.

Are These Watches Also Good for Other Sports?

All eight watches in this guide support a broad range of sport modes beyond swimming, including running, cycling, hiking, and gym workouts. The rugged construction that makes them suitable for pool use also holds up well outdoors.

If you are a multisport athlete who crosses between swimming, running, and cycling, look specifically for models with built-in GPS and at least five days of battery life in sport mode to avoid charging mid-training week.

For runners who want to compare options, wireless earbuds for running pair naturally with many of these watches for a complete workout setup.
