Scope and field of application

This International Standard specifies the requirements for two types of water-resistant watch, together with the corresponding methods of tests :

a) watches bearing the designation "water-resistant";

b) watches bearing the designation "water-resistant" with an additional indication of pressure or depth.

Watches bearing the designation "water-resistant" are intended for ordinary daily use and are resistant to sweat, water drops, rain, etc., and to immersion in water for 30 min at a depth of approximately 1 m. They are not intended for use under conditions where water pressure and temperature may vary significantly.

Watches bearing the designation "water-resistant" with an additional indication of pressure or depth are intended for ordinary daily use and to be resistant to water during exercises such as swimming. They may be used under conditions where water pressure and temperature vary significantly.

This International Standard does not apply to divers' watches, which are specified in ISO 6425.¹⁾
