The ISO 6425 reference standard establishes the minimum technical characteristics necessary for a clock to be defined underwater:

1 - Visibility at least 25 cm away
2 - Amagneticity Cash and movement
3 - Resistence to bump
4 - Resistance tosalt water
5 - Resistance to Water pressure
6 - Reliability standards of the individual parts of the clock.

The same provision determines the methods in which the aforementioned characteristics must be tested ... and lat the Japanese home it has never been saved To ensure maximum efficiency of its timepieces!

Just think aboutFurrow extreme tests made over the years... Seiko watches were fixed to hulls of submarines and submarines since the first years of brand activity, And at each test they have maintained readability and precision Ben Ltre 1000 m!
