Best Waterproof Smartwatches for Swimming & Diving

In 2025, waterproof smartwatches have become more than just a trendy tech accessory—they’re essential tools for a variety of activities, from fitness tracking to deep-water diving. As people continue to integrate smart devices into their everyday lives, manufacturers have upped the ante in terms of water resistance. Whether you're swimming in a pool, taking a dive into the ocean, or just braving a rainy day, there’s a smartwatch for every need. The question is: which one is best suited for your lifestyle?

Let’s explore the top waterproof smartwatches in 2025, focusing on their key features, durability, and special functionalities for swimming, diving, and daily use.

How to Choose the Best Waterproof Smartwatch in 2025?

When selecting the right waterproof smartwatch for your needs, consider the following factors:

Water Resistance Rating:
For swimming, a 50 m (5 ATM) rating is sufficient. However, if you plan on diving or engaging in extreme water sports, go for 100 m (10 ATM) or higher for additional durability.

Battery Life:
If you're into long-duration activities like diving, opt for a model with long battery life. Some models can last days on a single charge, even in active modes.

Swim and Dive Features:
Look for watches that specifically track swim metrics like stroke count, SWOLF score, and lap times. For divers, make sure your watch supports underwater tracking, depth measurement, and specialized dive logs.

Compatibility:
Ensure your smartwatch works well with your existing devices. Apple Watch Ultra 2 is best for iPhone users, while the Samsung Galaxy Watch works seamlessly with Android devices.

Smart Features:
Consider how much you want from your smartwatch in terms of notifications, music control, and other fitness features. Some models, like the Apple Watch Ultra 2, offer a lot of smart integrations, while others, like the Fitbit Charge 6, focus more on fitness.
