WHEN YOU WEAR YOUR WATCH IN WATER

Every watch has a specific level of water resistance, indicated in meters (m) or atmospheres (ATM). These values do not represent the actual depth to which a watch can be submerged, but rather the pressure level that the case can withstand under laboratory testing. Regular water-resistance testing – at least once a year, especially before the summer season – is essential, as gaskets age and lose elasticity over time.

Marking Atmospheres (ATM) Use / Protection
Water Resistant (30 m) 3 ATM Protection from rain and hand washing. Not suitable for submersion.
50 m 5 ATM Suitable for showering and light swimming, but not diving.
100 m 10 ATM Good for swimming and snorkeling, not for scuba diving.
200 m 20 ATM Suitable for underwater swimming and recreational diving.
300+ m 30+ ATM Professional diver’s watches.

Gaskets should be replaced during each maintenance or when the case is opened. After impact, repair, or battery replacement, a new water-resistance test is mandatory. Do not operate buttons or the crown underwater unless specified by the manufacturer.

Water resistance testing can be performed exclusively at our ShadiaN – Watchmakers service center, equipped with professional instruments for pressure, vacuum, and immersion simulation testing.
