WATER RESISTANCE

The ability of a watch case to resist the ingress of water and dust. Achieving water resistance requires a specific construction and the use of sealing gaskets. Water resistance and its certification are governed by ISO 22810 (for watches water-resistant above 2 bar, equivalent to NIHS 92-20) and ISO 6425 for dive watches (for a minimum water resistance of 10 bar).
