Best Cellular Smartwatch

Waterproof smartwatches are already commonplace, with most major brands offering models with a 50-meter (also known as 5 bar or 5 ATM) water resistance. Most smartwatches used to have an IP68 classification and were certified to resist submersion in shallow water for a short amount of time, but they weren’t meant to be used for swimming or water sports. IP68-rated watches are meant to endure accidental water exposure and the occasional dunking, but they are not designed to be used regularly underwater or for water-based sports such as swimming. If you want to swim with your smartwatch or expose it to water on a frequent basis, it should have a water resistance of at least 50 meters.
