My timepiece says its water resistant to 330 feet (100 meters). Why is it Ok for swimming and not diving?
A. Most models are rated to withstand water pressure up to 330 feet or 100 meters (there are some exceptions). In contrast to the term “waterproof,” water resistance is not a permanent condition; it must be maintained. The crown must be fully recessed and parts such as the crystal, case, and push buttons must remain intact for the timepiece to stay water-resistant.
