The requirements for diving watches are controlled through the ISO 6425 Global regular. The watches are examined in static or nonetheless h2o less than one hundred twenty five% from the rated (water) force, Consequently a view by using a 200-metre score will likely be drinking water-resistant if it is stationary and under 250 metres of static water. The testing of the drinking water-resistance is essentially various from non-dive watches, since every check out has to be thoroughly tested.
