Waterproof smartwatches have quickly become a must-have for active users. Whether you swim regularly, go to the gym or just want peace of mind when it rains, a water-resistant watch lets you live freely without constantly worrying about splashes and sweat. But how “waterproof” are they really, and what can you safely do with them?

In this article, we’ll break down how waterproof smartwatches perform in swimming and everyday use, and what you should check before buying one.

What Does “Waterproof” Really Mean in Smartwatches?

Most smartwatches are not truly 100% “waterproof”; they are water-resistant to a certain level. This resistance is usually shown in two ways:

• IP Rating (e.g., IP67, IP68)

• ATM / Water Resistance Rating (e.g., 3ATM, 5ATM, 10ATM)

In simple terms:

• IP67 / IP68 – Good for splashes, rain, sweat and brief submersion.

• 5ATM (50m) – Generally suitable for swimming in a pool.

• 10ATM (100m) – Better for more intense water activities, like snorkeling or stronger pool workouts (still not for deep diving).

Always remember: these ratings are tested in controlled lab conditions, not in hot showers, saunas or the sea with soap and shampoo.

How Waterproof Smartwatches Perform in Swimming

If you’re a swimmer, the rating matters a lot.

For casual pool swimmers:

• A smartwatch with 5ATM water resistance is usually recommended.

• It can typically handle:

  • Pool swimming

  • Shallow water activities

  • Repeated submersion during laps

Many waterproof smartwatches also include swim tracking modes, such as:

• Lap counting

• Distance tracking

• Stroke detection (in advanced models)

• Calories burned and heart rate (if the sensor works well in water)

These features help you measure performance instead of just time in water.

For open water swimmers:

• Look for models that mention open-water swimming or GPS swimming in the specs.

• Stronger water resistance (like 5ATM or 10ATM) is safer for lakes, rivers or the sea.

• Salt water is more aggressive than pool water, so rinsing the watch with fresh water after swimming is important.

Daily Use: Rain, Sweat, Handwashing and Showers

Even if you never swim, a waterproof smartwatch is still useful in daily life.

A good water-resistant watch can usually handle:

• Rain and accidental splashes – No need to hide your wrist every time it drizzles.

• Sweat from workouts – Ideal for running, gym sessions and sports.

• Handwashing – Quick rinses and splashes are normally fine.

However, there are some important things to avoid:

• Hot Showers & Sauna: High heat and steam can damage seals and glue inside the watch.

• Soaps, Shampoo and Detergent: Chemicals and foam can slowly affect the rubber gaskets and microphones.

• Pressing buttons underwater: On many models, pressing physical buttons under water increases pressure and can push water inside.

If you want your watch to last longer, treat the “waterproof” feature as extra protection, not a license to abuse it.

How Long Do Waterproof Smartwatches Stay Water-Resistant?

Water resistance is not permanent. Over time, gaskets, seals and adhesives can wear out due to:

• Repeated exposure to water, sweat and chemicals

• Drops, shocks or bending

• Heat, sun and long-term use

That’s why some brands clearly mention that water resistance is not guaranteed forever. If you use your watch heavily in water, you should:

• Take extra care after big impacts

• Avoid unnecessary hot water exposure

• Follow the brand’s maintenance advice

For heavy swimmers, upgrading to a newer model every few years might actually be more reliable.

Tips to Protect Your Waterproof Smartwatch

To get the best performance in swimming and daily life:

1. Check the rating before use

   • For swimming: aim for at least 5ATM.

   • For everyday splash use: IP67/IP68 can be enough.

2. Rinse after swimming

   • After pool or sea water, gently rinse the watch with clean fresh water and dry it with a soft cloth.

3. Avoid hot environments

   • Don’t wear the smartwatch in hot showers, steam rooms or saunas.

4. Don’t press buttons underwater

   • Use touch or pre-set swim modes before entering the water, if possible.

5. Use suitable straps

   • Silicone or TPU straps are better for swimming than leather, which absorbs water and gets damaged.

Choosing the Right Waterproof Smartwatch for Your Lifestyle

When shopping for a waterproof smartwatch, think about how you actually live:

• Primarily daily use (office, casual, light workouts):

  • IP67 / IP68 rating is usually enough.

  • Focus on comfort, battery life and notifications.

• Regular swimming or gym use:

  • 5ATM water resistance or higher.

  • Look for dedicated swim modes, heart rate tracking and good strap quality.

• Outdoor or adventure use:

  • Higher ATM ratings, strong build and good GPS performance.

  • Durable strap, shock resistance and long battery life.

Also consider:

• Warranty and after-sales support in your country

• Availability of replacement straps

• Compatibility with your smartphone (Android/iOS)

• Local service support (very important for long-term use)

Final Thoughts

Waterproof smartwatches can perform very well in both swimming and daily use if you understand their limits. The right rating, proper care and realistic expectations will help your watch stay safe in the pool, in the rain and in your everyday routine.

Instead of worrying every time your wrist gets wet, you can focus on your fitness, your notifications and your lifestyle—exactly what a modern smartwatch is meant to do.
