Smartwatches have changed how we stay connected, track our health, and manage daily life. From checking messages to monitoring heart rate, these tiny devices are now a part of many wrists. But as smartwatches become more popular, people have one big question: Are smartwatches waterproof? The answer is not as simple as “yes” or “no.” Waterproofing means different things for different watches. Some can handle a splash, while others can go deep underwater. Understanding these differences is important before you buy or use a smartwatch in wet conditions.
This guide will break down what “waterproof” really means for smartwatches. You’ll learn about water resistance ratings, how to read labels, and what real-life activities each watch can handle. We’ll compare top models, explain common mistakes, and share tips to keep your smartwatch safe and working well.
By the end, you’ll know how to choose the right smartwatch for your needs—without risking water damage.
What Does “waterproof” Mean For Smartwatches?
People often say a device is “waterproof,” but for smartwatches, this word is not completely accurate. No smartwatch is 100% waterproof in every situation. Instead, most are water-resistant to different levels. This means they can survive contact with water up to a certain point, but not forever or in all conditions.
The difference matters. A water-resistant watch might be fine in the rain, but not safe for diving. Even the most advanced watches have limits. Understanding this can help you avoid accidents and disappointment.
Understanding Water Resistance Ratings
Manufacturers use official ratings to show how much water a smartwatch can handle. The two main systems are IP ratings and ATM ratings. Let’s look at both.
Ip Ratings (ingress Protection)
IP ratings are made up of two numbers, like IP68. The first number is for dust, the second for water.
- IP67: Protected against dust and can handle being under 1 meter of water for up to 30 minutes.
- IP68: Stronger protection. Can survive being deeper than 1 meter, sometimes up to 1.5 or 2 meters, for longer times.
An IP rating does not always mean a watch is good for swimming. It is usually for short contact with water, like hand washing or rain.
Atm Ratings (atmospheres)
ATM shows how much pressure a watch can take under water.
- 3 ATM (30 meters): Can handle splashes and rain, but not swimming.
- 5 ATM (50 meters): Good for swimming, showering, or shallow water.
- 10 ATM (100 meters): Safe for snorkeling and water sports, but not deep diving.
The “meters” do not mean you can dive to that exact depth. It is about pressure in a lab test, not real life.
How Ratings Compare
Here’s a quick look at how IP and ATM ratings match up for daily life.
| Rating | What It Means | Safe Activities |
|---|---|---|
| IP67 | Short, shallow water contact | Hand washing, rain |
| IP68 | Deeper, longer water contact | Shower, shallow swim |
| 3 ATM | Splashes only | Rain, sweat |
| 5 ATM | Swim and shower safe | Swimming, showering |
| 10 ATM | High water pressure safe | Snorkeling, water sports |
Smartwatch Water Resistance In Real Life
Many people buy a smartwatch with a good rating and think it is safe for everything. But daily life is different from lab tests.
Common Water Exposures
- Hand Washing: Most smartwatches with IP67 or higher can handle this.
- Rain: Almost all smartwatches sold today can survive rain.
- Swimming: Only watches with at least 5 ATM or IP68 should be used for swimming.
- Showering: Be careful. Hot water and soap can damage seals even if the rating looks strong.
- Diving: Only special watches with 10 ATM or more are made for diving. Most smartwatches are not safe for deep water.
Real-world Examples
- The Apple Watch Series 8 has a 50-meter water resistance rating (5 ATM). It is safe for swimming, but not for scuba diving.
- The Samsung Galaxy Watch5 Pro is rated IP68 and 5 ATM. Good for swimming, but not deep diving.
- The Garmin Fenix 7 offers 10 ATM. You can use it for snorkeling and water sports, but not for diving with tanks.
Activities And What Rating You Need
It’s easy to get confused by numbers and terms. Here’s a guide to choose the right smartwatch for different activities.
| Activity | Minimum Rating Needed | Notes |
|---|---|---|
| Hand washing | IP67 / 3 ATM | Most smartwatches are safe |
| Rain | IP67 / 3 ATM | Safe for almost all models |
| Swimming (pool) | IP68 / 5 ATM | Check user manual for limits |
| Shower | IP68 / 5 ATM | Hot water can still cause damage |
| Snorkeling | 10 ATM | Not for deep diving |
| Diving | 20 ATM or higher | Very few smartwatches qualify |

How To Read Manufacturer Claims
Some brands use big words to make their watches sound better than they are. “Waterproof up to 50 meters” does not mean you can dive to that depth and stay there. Here’s how to read the fine print:
- Check the manual: Always read the user guide for real-life limits.
- Look for exclusions: Some brands say “not for saltwater” or “not for hot water.”
- Warranty voids: If you use a watch outside its rating, the warranty may not cover water damage.
- Test conditions: Ratings are given in controlled labs. Real water has pressure, movement, and chemicals that are not tested.
Common Mistakes When Using Smartwatches In Water
Even with a high rating, mistakes can damage your watch. Here are the most common errors:
- Wearing in hot water: Hot showers, saunas, and hot tubs can break seals.
- Pressing buttons underwater: This can let water in, even if the watch is rated for swimming.
- Not rinsing after saltwater: Salt can corrode seals and metal. Rinse with fresh water after swimming in the sea.
- Using soaps or chemicals: These can weaken seals and damage sensors.
- Ignoring wear and tear: Scratches, cracks, or old seals can reduce water resistance over time.
Many people think a high ATM rating means “no worries. ” In reality, care is still needed.
How Water Resistance Changes Over Time
Water resistance is not permanent. Gaskets and seals can dry out or break with age. Here’s what can affect a watch over time:
- Impact: Dropping or hitting the watch can cause tiny cracks.
- Aging: Rubber seals dry out and lose their shape.
- Heat: High temperatures speed up wear on seals.
- Maintenance: Some watches need the seals checked and replaced after a few years.
Manufacturers rarely cover water damage if the watch is old or poorly maintained. Some suggest a “water resistance test” every year for heavy users.
Can You Swim Or Shower With Your Smartwatch?
This is one of the most-asked questions. The answer: it depends on the specific rating and the type of water.
Swimming
If your smartwatch is rated 5 ATM or IP68, it is usually safe for pool swimming. But always check:
- Pool chemicals: Chlorine can harm seals. Rinse the watch after swimming.
- Long swims: Prolonged exposure to water can still risk leaks over time.
- Saltwater: Always rinse off salt after swimming in the sea.
Showering
Even with a high rating, showering is risky:
- Hot water: Makes seals expand and contract, which can lead to leaks.
- Soap and shampoo: Chemicals can break down water resistance.
- Steam: Steam can get past seals more easily than liquid water.
If you want your smartwatch to last, take it off before hot showers.
What About Diving And High-pressure Activities?
Most smartwatches are not made for deep diving. Even if they have a 10 ATM rating, this is often for surface water sports, not deep dives. For scuba diving, only a few special smartwatches are safe.
- Apple Watch Ultra: Certified for diving to 40 meters.
- Garmin Descent Mk2i: Made for diving, with dedicated features.
- Suunto D5: A dive computer in smartwatch form.
If you need a watch for diving, always look for EN13319 certification. This is the international standard for dive computers.
How To Protect Your Smartwatch From Water Damage
Being careful is the best way to make your smartwatch last. Here are some tips:
- Check the rating before use: Know what your watch can handle.
- Rinse after saltwater or chlorine: This prevents corrosion.
- Avoid hot water and chemicals: Take off your watch before hot showers or saunas.
- Do not press buttons underwater: This can break seals.
- Inspect for damage: Look for cracks or loose parts.
- Have seals checked every year: For heavy users or older watches.
Comparing Water Resistance Across Brands
Brands use different ways to show water resistance. Here’s how some of the top brands compare:
| Brand | Typical Rating | Recommended Use |
|---|---|---|
| Apple | 5 ATM (Series 8), 10 ATM (Ultra) | Swimming, water sports, shallow diving (Ultra) |
| Samsung | IP68, 5 ATM | Swimming, showering |
| Garmin | 10 ATM | Swimming, snorkeling, some diving |
| Fitbit | 5 ATM | Showering, swimming |
| Suunto | 10 ATM | Snorkeling, water sports, diving (some models) |
Non-obvious Insights Most People Miss
Many users think that “waterproof” is forever. But:
- Regular use can lower water resistance. Every bump, scratch, or old seal makes leaks more likely. Even a small crack can ruin a watch.
- Water resistance tests are not permanent. When a watch is made, it passes a water resistance test in a lab. But with age, the seals can fail. If you swim a lot, you might need your watch checked every year.
- Smart features can add risk. Microphones, speakers, and charging ports are all places where water can get in. Even on a “waterproof” watch, these parts are more likely to fail first.
How To Choose The Right Waterproof Smartwatch
When picking a smartwatch, think about your real needs:
- Daily wear only? Most watches with IP67 or IP68 are enough for hand washing and rain.
- Swimming often? Choose at least 5 ATM or IP68. Look for models with swim tracking.
- Outdoor and water sports? Go for 10 ATM. Consider rugged brands like Garmin or Suunto.
- Diving? Only buy a model with EN13319 certification and 10 ATM or higher.
Also, read reviews and user stories. Some watches have high ratings but problems with water damage in real life. User experience can tell you more than a number.

Frequently Asked Questions
How Do I Know If My Smartwatch Is Waterproof?
Check the user manual or look for an IP or ATM rating on the box or website. IP67 or IP68 means the watch is water-resistant, not fully waterproof. For swimming, look for 5 ATM or higher.
Can I Wear My Smartwatch While Swimming?
If your watch is rated 5 ATM or IP68, yes, you can swim with it. But avoid pressing buttons underwater, and always rinse it after swimming, especially in salt or chlorinated water.
Is It Safe To Shower With My Smartwatch?
It depends on the rating. Most 5 ATM or IP68 watches can handle a shower, but hot water and soap can damage the seals over time. For best results, take your watch off before hot showers.
What Should I Do If Water Gets Inside My Smartwatch?
Turn off the watch right away. Dry it with a towel. Do not use a hair dryer or oven. Take it to a service center as soon as possible. Water inside can cause permanent damage if not fixed quickly.
Do Smartwatches Lose Water Resistance Over Time?
Yes. Seals and gaskets wear out with age, heat, and impact. If you use your watch in water often, have it checked by a professional every year to keep it safe.
Smartwatches are getting stronger and safer in water every year. But no watch is truly “waterproof” for every situation. By understanding the ratings, caring for your device, and choosing wisely, you can enjoy all your favorite activities without worry. Stay informed, stay safe, and your smartwatch will last much longer.
