The term "water-tightness" stands for the property of not allowing water to penetrate the watch. Watches can be protected against water and moisture. However, due to the complexity of the individual components and their construction, they can never be completely tight, but
only more or less resistant to water penetration.
The water tightness is usually given in bar (bar), in meters (m) or atmospheres (ATM). However, meter data cannot be equated with the depth of a dive. The durability and durability of the water tightness of a watch is limited and is influenced by the daily use of the watch. Seals age differently depending on the use and wearing behavior. Strong temperature fluctuations, violent impacts or chemical reactions through sweat, solvents and cosmetics accelerate the aging of the density elements. Furthermore, the watch should be rinsed with fresh water after the stay in the sea, since the salt water can attack the seals of the watch. We recommend an annual inspection of the watch for water tightness.
Information on the water tightness of your watch can be found on the bottom of the case (in ATM) or on the dial of the watch (in meters). The following information shows which activities are possible during normal use without damaging your watch.
3 bar ≈ 3 ATM (≈ 30 m)
It protects the watch from sweat and water splash. The watch is not suitable for showers or swimming.
5 bar ≈ 5 ATM (≈ 50 m)
The watch is suitable for everyday use and can be worn, for example, by washing hands, rain, showering or car washing.
10 bar ≈ 10 ATM (≈ 100 m)
The watch is suitable for everyday use and can be worn, for example, by washing hands, rain, showering or car washing. Furthermore, the watch can be used for light water sports such as swimming or snorkeling.
20/30 bar ≈ 20/30 ATM (≈ 200 / 300m)
The watch is suitable for daily use and can be used in addition to diving with equipment.
100 bar ≈ 100 ATM (≈ 1000 m)
This watch is suitable for daily use as well as professional diving sport.
