Yes. Most Garmin watches with a 5 ATM water-resistance rating are suitable for swimming, while 10 ATM models provide a higher pressure margin for tougher water activities. On supported watches, Pool Swim can track lengths, distance, pace, strokes, Swolf, and rest intervals, while Open Water uses satellite positioning for distance and pace. Always check the exact rating and swim profiles for your Garmin model before getting in the water.
Quick Answer
You can swim with most Garmin watches rated 5 ATM or higher. A 5 ATM rating is suitable for swimming, while 10 ATM provides a higher pressure margin. For tracking, choose Pool Swim or Open Water if your model supports those activities, and set the correct pool length before a pool session.
Key Takeaways
Key Takeaways
- Garmin classifies 5 ATM watches as suitable for swimming, but the available swim-tracking profiles vary by model.
- A 10 ATM rating withstands greater pressure and is also suitable for high-speed water sports, but ordinary open-water swimming does not automatically require 10 ATM.
- Pool Swim calculates distance from completed pool lengths, so entering the correct pool size is essential.
- Open Water tracking uses satellite positioning; wait for satellite acquisition before starting the activity.
- Rinse the watch with fresh water after chlorine or saltwater exposure and follow the model-specific manual for underwater button use.

Can You Swim With a Garmin Watch?
Yes—many Garmin watches rated 5 ATM or higher are designed for swimming. Garmin’s water-rating definitions list 5 ATM as suitable for swimming, diving into water, and snorkeling. A 10 ATM rating tolerates still greater pressure and is also suitable for high-speed water sports.
A 5 ATM rating means the watch is tested to pressures equivalent to 50 meters; it does not mean every 5 ATM Garmin is a scuba-diving watch.
Water resistance and swim tracking are separate questions. A watch may be water-resistant enough for swimming, but you should still confirm whether that specific model includes Pool Swim, Open Water, or both. For example, Garmin’s Forerunner 165 manual documents both Pool Swim and Open Water activities.
In a pool, compatible Garmin watches can record completed lengths, distance, pace, stroke information, Swolf, and rest intervals. In open water, compatible models use satellite positioning to record distance and pace after acquiring a satellite signal.
Warning: Do not interpret a 5 ATM or 10 ATM rating as automatic scuba-diving certification. Use a Garmin for scuba only when that exact model carries an explicit Dive rating and the owner’s manual approves the intended depth and activity.
After swimming, Garmin recommends rinsing watches with fresh water after exposure to chlorine, salt water, sunscreen, or other harsh substances. Water-resistance precautions and underwater-control instructions can vary by model, so the exact owner’s manual takes priority.
Which Garmin Watches Are Swim-Safe?
A Garmin watch rated 5 ATM is generally suitable for swimming according to Garmin’s water-rating definitions. Many Forerunner, Venu, and vívoactive models use this rating. Higher-end outdoor watches may carry a 10 ATM rating, while some current Garmin watches also carry a separate dive certification.
Do not rely only on a series name. Check the specifications for the exact model because water ratings, swim profiles, touchscreen behavior, and supported swim metrics can differ.
Swim Resistance Ratings
A 5 ATM Garmin withstands pressures equivalent to a depth of 50 meters in standardized testing and is listed by Garmin as suitable for swimming. A 10 ATM model withstands pressures equivalent to 100 meters and adds a larger margin for higher-pressure activities such as high-speed water sports.
Those meter figures describe test pressure; they should not be treated as a recommendation to take an ordinary 5 ATM watch scuba diving to 50 meters or a 10 ATM watch to 100 meters.
Garmin also uses a separate Drive/Dive rating for watches specifically tested for diving. For example, the fēnix 9 specification lists 10 ATM plus a 4 ATM Dive rating under EN 13319, with diving functions designed for depths up to 40 meters.
For ordinary swimming, the practical rule is simple: confirm the model’s water rating, confirm that Garmin approves swimming for it, and then check whether the watch provides the swim activity profile you want to record.
Best Swim Models
The right Garmin depends on whether you mainly swim in a pool, train across several sports, need advanced satellite tracking, or want a watch with dedicated diving capability.
| Model | Water Rating | Good Fit For |
|---|---|---|
| Forerunner 165 | Swim, 5 ATM | Pool and open-water swimmers who want core training metrics in a lighter running-focused watch |
| Forerunner 570 | Swim, 5 ATM | Multisport athletes who want Pool Swim, Open Water, triathlon support, and newer training features |
| Forerunner 970 | Swim, 5 ATM | Advanced multisport users who want premium navigation and training tools with pool and open-water support |
| fēnix 9 / 9 Pro | 10 ATM + 4 ATM Dive (EN 13319) | Swimming, multisport, rugged outdoor use, and supported diving activities |
| Enduro 3 | 10 ATM | Endurance-focused athletes who prioritize long battery life and rugged outdoor use |
The fēnix 8 remains a capable swim and multisport watch, but it is no longer Garmin’s newest fēnix generation. Garmin introduced the fēnix 9 and fēnix 9 Pro in August 2026.
Garmin Water Resistance Ratings Explained
Garmin expresses wearable water resistance through ratings such as ATM and Dive. The rating describes the pressure a device is designed to withstand under specified test conditions and the types of activities Garmin considers suitable.
| Rating | Pressure Equivalent | Garmin-Listed Uses |
|---|---|---|
| 5 ATM / Swim | 50 meters | Swimming, showering, diving into water, snorkeling |
| 10 ATM | 100 meters | Swimming, snorkeling, diving into water, high-speed water sports |
| Dive | Model-specific stated depth | Scuba diving and other activities approved by the specific dive-rated model |
A higher ATM number does not automatically improve swim-tracking accuracy. It describes water resistance, while tracking accuracy depends on the sensors, activity profile, satellite system, pool setup, swimming technique, and software of the individual watch.
Garmin describes these products as water-resistant rather than guaranteeing that a watch is permanently “waterproof.” Damage, harsh treatment, chemical exposure, or use outside the instructions can affect the device, so inspect the watch if it has been dropped or visibly damaged.
How Garmin Tracks Pool Swims
Garmin pool swim tracking uses completed pool lengths rather than GPS to calculate distance. Because of that, the pool size entered before the session must match the actual pool length.
On compatible watches, the activity can record lengths, distance, pace, stroke count, stroke rate, stroke type, Swolf, intervals, and rest periods. Wrist-based heart rate is also available during swim activities on many newer models, including the Forerunner 165.
Pool Size Settings
The first time a supported Garmin watch starts a Pool Swim activity, it may ask for the pool size. Standard options commonly include 25 meters, 50 meters, and common yard-based lengths; compatible watches also allow a custom size.
The watch converts completed lengths into total distance, so an incorrect setting produces an incorrect distance total even if the watch counts every length correctly.
- Select the correct preset pool length when available.
- Use a custom size if the pool is not a standard length.
- Enable the pool-size prompt if you regularly swim at different pools.
- Swim the complete length before turning around.
- Use a strong push off the wall and glide before beginning the first stroke.
Pro Tip: Garmin recommends using one stroke type for the entire pool length and making a clear push-off and glide at the wall. For kick sets or unusual drills, use the watch’s Drill Log when available instead of expecting automatic stroke detection to identify the movement.
Stroke And Swolf Tracking
During supported pool activities, Garmin can identify freestyle, backstroke, breaststroke, and butterfly at the end of each completed length. Mixed and Drill labels may also appear in the swim history.
A Garmin stroke is counted each time the arm wearing the watch completes a full cycle. Because the watch is on only one wrist, this definition matters when comparing Garmin’s stroke count with other swimming metrics.
Swolf combines the time required for one pool length with the number of strokes recorded for that length. For example, 30 seconds plus 15 strokes produces a Swolf of 45.
A lower Swolf generally indicates greater efficiency under comparable conditions, but it should be compared using similar pool lengths, stroke types, and effort levels. It is not a universal score for deciding which swimmer is faster or more skilled.
Swim data can be reviewed in Garmin Connect after the activity syncs.
How to Set Pool Size
- Open the Pool Swim activity on the watch.
- Open the activity settings or follow the initial setup prompt.
- Select Pool Size.
- Choose the correct standard length or enter a custom length.
- Start the activity timer before swimming.
- Save the activity when the session is complete.
Button names and menus vary between Garmin models. On the Forerunner 165, for example, Garmin documents the path as Pool Swim > Pool Swim Settings > Pool Size. The watch also offers a prompt option that asks for pool length when starting a swim.
Because pool distance is calculated from completed lengths, entering the wrong pool size can make every distance, pace, and interval total misleading even when the watch detects the turns correctly.
How Garmin Tracks Open Water Swims
Open-water swimming relies on satellite positioning rather than a known pool length. On a Garmin with an Open Water activity, go outside and allow the watch to locate satellites before starting the activity timer.
During the swim, supported watches can record metrics such as distance, pace, and stroke rate. GPS reception is inherently more difficult during swimming because the watch repeatedly moves above and below the water surface, so recorded tracks may not look as smooth as running or cycling tracks.
Higher-end Garmin watches may offer multi-band GNSS or Garmin’s automatic satellite-selection technologies. These systems can improve positioning consistency in challenging environments, but the exact satellite options vary by model and activity.
Note: Wait for the satellite-ready indication before entering the water. Starting before the watch has established a position can reduce the quality of the beginning of the recorded route.
After the session, the activity can sync to Garmin Connect for review. Garmin calculates open-water Swolf over 25 meters rather than one physical pool length.
For open water, the watch needs a satellite position before the activity begins; pool swims instead calculate distance from completed lengths.
Swim Metrics: Strokes, Swolf, and Rest
Garmin swim metrics are designed to separate active swimming from recovery and provide repeatable measurements of pace and efficiency.
- Stroke count: Counts a stroke each time the watch-wearing arm completes a full cycle.
- Stroke type: On supported pool profiles, identifies freestyle, backstroke, breaststroke, butterfly, mixed intervals, and drill entries.
- Swolf: Combines time and strokes into an efficiency metric.
- Intervals: Group one or more consecutive pool lengths.
- Rest: Separates recovery time from active swimming.
On watches with Auto Rest, the watch can detect when the swimmer stops and create a rest interval. For example, Garmin documents on the Forerunner 165 that a rest lasting more than 15 seconds can trigger an automatic rest interval when the feature is enabled.
Manual rest is useful for short recoveries or when precise interval timing matters. Garmin notes that swim data is not recorded during a marked rest interval.
For drills such as kick sets or one-arm swimming, use Drill Log on compatible watches. These movements do not always resemble one of the four major strokes closely enough for normal automatic stroke recognition.
How to Care for Your Garmin After Swimming
After swimming, especially in chlorinated or salt water, rinse the Garmin watch thoroughly with fresh water. Garmin’s current device-care guidance also warns against harsh chemical cleaners, solvents, extreme shock, and prolonged exposure to extreme temperatures.
Swimming and diving are different demands, and a swim-rated watch is not built for depth. If you dive as well as swim, our Garmin Descent comparison covers the models rated for it.
| Action | Why It Helps |
|---|---|
| Rinse with fresh water | Removes chlorine, salt, sunscreen, and other residues |
| Allow the watch to dry completely | Keeps moisture away from charging contacts and skin |
| Avoid harsh cleaners | Protects plastic components and finishes |
| Check for visible damage | Helps identify cracks or impact damage before the next swim |
| Follow the manual for underwater buttons | Many Garmin manuals advise against pressing buttons underwater unless the model specifically permits it |
If your watch uses a leather band, Garmin generally advises keeping that band dry and using a silicone or other water-suitable band for swimming.
Some newer Garmin watches have a speaker and microphone. After swimming, trapped water can temporarily make them sound quieter. On models such as the Forerunner 570, Garmin says the moisture may take up to 24 hours to evaporate and provides a water-ejection feature.
Warning: Garmin generally advises against pressing watch buttons underwater unless the owner’s manual for that specific model states otherwise. Dive-rated models can have different controls and instructions, so follow the exact manual rather than applying one rule to every Garmin watch.
Frequently Asked Questions
How Do I Know if My Garmin Is Waterproof?
Check the Water Rating in the specifications for your exact Garmin model. A 5 ATM rating is listed by Garmin as suitable for swimming. Garmin describes these devices by their water-resistance rating rather than treating every model as permanently waterproof.
Which Garmin Watch Is Good for Swimming?
Forerunner 165 is a straightforward 5 ATM option with Pool Swim and Open Water tracking. Forerunner 570 and 970 add more multisport and training features. fēnix 9 adds a 10 ATM rating plus a separate 40-meter Dive rating, while Enduro 3 is a 10 ATM endurance-focused option.
How Do I Set My Garmin Watch for Swimming?
Select Pool Swim for a pool or Open Water for outdoor swimming if those profiles are available on your model. For a pool session, confirm the pool length before starting the timer. For open water, go outside and wait for the watch to acquire satellites before starting.
Do I Need to Put My Garmin Watch in Water Mode?
No universal Garmin “water mode” is required to make the watch water-resistant. Start the appropriate Pool Swim or Open Water activity to record swim data. Some touchscreen models automatically enable a touch lock during swimming, but that feature prevents accidental screen input; it does not create the watch’s water resistance.
Can I Press Garmin Watch Buttons Underwater?
Many Garmin manuals tell users to avoid pressing buttons underwater, but some dive-rated or newer models are designed differently. Follow the owner’s manual for your exact watch rather than assuming the same rule applies to every Garmin.
Why Is My Garmin Counting the Wrong Pool Distance?
First check that the pool size is correct. Then swim full lengths, make a clear push-off and glide at each wall, and avoid changing stroke type partway through a length. Use Drill Log for kick sets or unusual drills when your watch supports it.

Conclusion
A Garmin watch can be used for swimming when its water-resistance rating and model instructions approve the activity. A 5 ATM watch is suitable for ordinary swimming, while 10 ATM models provide a higher pressure margin. Dive use requires a model with the appropriate dedicated Dive rating rather than relying on ATM alone.
For pool swimming, select Pool Swim, enter the correct pool length, start the activity timer, and use clear wall push-offs for better length detection. For open water, select Open Water and wait for satellite acquisition before starting. After either type of swim, rinse away chlorine or salt with fresh water, let the watch dry, and follow the exact owner’s manual for underwater controls and band care.
