Waterproof watches are timepieces designed to resist the penetration of water. They are often used in water-related activities, such as swimming, snorkeling, diving, or for everyday wear in wet conditions. It’s important to note that the term “waterproof” has been largely replaced by “water-resistant” in the watch industry because no watch is entirely impervious to water. Instead, watches are rated for their water resistance according to specific standards and markings.
