Some smartwatches can handle water, but none should be assumed waterproof. Check the exact model’s water rating and care instructions before swimming, showering, or taking it into water.

A rating describes resistance under certain conditions, not a promise that water can never get inside. The right choice depends on the activity, the watch’s instructions, and how it has been cared for.

Are smartwatches waterproof or water-resistant?

Most watches described as water-resistant have limits; the word “waterproof” is not a safe substitute for checking the model’s rating. Read the manufacturer’s guidance for the exact watch and the activity you have in mind.

A watch that tolerates everyday splashes may not be suitable for swimming. A model with a stronger water-resistance rating may allow more water exposure, but that still does not mean it is suitable for every sport or setting.

Water resistance can also change as seals wear, age, or get damaged. If the watch has been dropped, repaired, or exposed to conditions outside its instructions, don't rely on the original rating without checking with the manufacturer.

What do smartwatch water ratings mean?

Ratings such as ATM, meters, and IP codes describe different kinds of protection. Don't treat the numbers as interchangeable or as a simple measure of how deep you can safely take a watch.

ATM ratings relate to pressure resistance under controlled test conditions. A label such as 5 ATM or 10 ATM does not, by itself, tell you that every watch with that rating is right for swimming or diving; the maker’s activity guidance matters.

IP ratings describe protection against dust and water ingress under specified test conditions. The code and its accompanying guidance matter, since a rating for splashes or temporary immersion doesn't automatically cover swimming, hot water, or water sports.

If a watch page uses a depth figure, treat it as manufacturer guidance for that model rather than a general rule for all watches. Movement through water, water temperature, and button use can make real conditions differ from a controlled test.

Can you swim with a smartwatch?

Swim only when the manufacturer says your specific model is suitable for swimming. Check its instructions for pool or open-water use, button operation, and any care steps afterward.

Don't infer swimming suitability from a splash rating, a marketing image, or a general water-resistance number. If the instructions exclude swimming or don't make the activity clear, choose a watch with explicit swimming guidance.

For an Apple Watch, see our guide to whether you can swim with an Apple Watch. It focuses on the model-specific guidance you should check before taking that watch into a pool or open water.

Is a 10 ATM smartwatch safe for every water activity?

A 10 ATM rating is not a blanket approval for every water activity. Follow the manufacturer’s instructions for the particular model and avoid assuming it covers diving, fast-moving water, or hot water.

The Garmin Instinct 3 Solar 45mm is described as 10 ATM water-rated. It may suit readers who want a rugged watch with a stated water rating, but check Garmin’s activity guidance before choosing it for a specific kind of water exposure.

What should you check before wearing a watch in water?

Look up the exact model’s water rating and allowed activities before exposure. Also check whether the watch has been damaged, repaired, or used in conditions that could affect its seals.

Use this quick checklist:

• Find the rating printed for your exact model, not just the product family.
• Check the manufacturer’s instructions for swimming, diving, showering, and hot water.
• Confirm whether buttons or the touchscreen can be used while wet or underwater.
• Check the care instructions for rinsing and drying after salt water, pool water, or sweat.
• Avoid relying on water resistance if the watch has a cracked screen or has taken a hard impact.

A watch’s features can help you compare options, but they don't replace model-specific care instructions. Our smartwatch buying guide covers the broader choices to consider, including how a watch fits your everyday use.

Do buttons affect water resistance?

Follow the watch maker’s instructions about pressing buttons in water. Some models restrict button use while submerged, and the rule can differ between devices.

Touchscreens can also behave differently when wet. If you need to change settings during a swim, learn the permitted controls before you start rather than experimenting in the water.

Which smartwatch features may suit water activities?

Choose based on the activity guidance first, then compare the features you’ll use. GPS, workout tracking, and battery life can matter for outdoor exercise, but none proves a watch is safe for a given water setting.

The Garmin Forerunner 165 is a running smartwatch with built-in GPS and wrist-based heart rate. Its features don't specify a water rating, so check Garmin’s guidance before considering it for swimming.

The Apple Watch SE 3 GPS 44mm includes workout tracking and works with an iPhone or Wi-Fi. Check Apple’s instructions for its water rating and permitted activities before using it around water.

For longer outings, a watch’s battery and GPS features may be useful, but water suitability remains a separate question. Our guide to smartwatches for hiking and long trail days helps compare watches for outdoor use.

How should you care for a smartwatch after water exposure?

Follow the manufacturer’s cleaning and drying instructions after water exposure. Salt, pool chemicals, soap, and sweat can leave residue, so check the model’s guidance rather than using a one-size-fits-all routine.

If the instructions allow rinsing, use the recommended method and dry the watch as directed. Don't use heat, compressed air, or sharp tools to dry or clear openings unless the maker explicitly permits it.

Avoid charging a wet watch. Check the charging area and cable connection, and wait until everything is fully dry before charging, following the maker’s instructions.

A smartwatch that shows moisture inside, stops responding, or develops screen or charging problems should be handled according to the manufacturer’s support guidance. Don't assume that a water rating means damage is covered by a warranty.

Which smartwatch should you choose for water resistance?

Choose a watch whose maker explicitly supports your intended activity, then compare the features that matter to you. A stated rating helps narrow options, but the activity instructions and the watch’s condition still matter.

The Garmin Instinct 3 Solar 45mm has a stated 10 ATM rating. The other products here may suit different exercise or everyday needs, but confirm their water guidance before using them in water.

For comfort during daily wear, see how to wear a smartwatch properly. A secure, comfortable fit helps you wear a watch as intended, while water use still depends on its rating and care instructions.

When in doubt, keep the watch out of water until you confirm the model’s guidance. That simple rule is safer than guessing from the word “water-resistant” alone.

Frequently asked questions

Are smartwatches waterproof?

Some smartwatches are rated to resist water in specific conditions, but “waterproof” can imply more protection than a rating promises. Check the exact model’s instructions for swimming, depth, and water exposure, and avoid assuming that a splash rating means the watch is safe to swim with.

What does 10 ATM mean on a smartwatch?

A 10 ATM rating identifies a level of water resistance under defined test conditions, but it does not make every water activity safe. Follow the watch maker’s instructions for swimming, diving, and hot water, since movement, pressure, and temperature can affect exposure.

Can I shower with a water-resistant smartwatch?

Check the maker’s instructions before wearing a water-resistant smartwatch in the shower. Soap, shampoo, hot water, and steam can create conditions that differ from ordinary splashes or swimming, and a water rating alone may not cover them.

Does water resistance last forever?

No, water resistance can decline as seals age or the watch is damaged. Follow the maker’s care guidance, inspect the watch after impacts, and avoid pressing buttons underwater unless the instructions say that is allowed.
