The standards for diving watches are regulated via the ISO 6425 Worldwide regular. The watches are analyzed in static or nevertheless h2o less than a hundred twenty five% from the rated (h2o) tension, Therefore a check out having a 200-metre ranking might be water-resistant whether it is stationary and underneath 250 metres of static water. The tests with the h2o-resistance is fundamentally distinct from non-dive watches, simply because each and every watch must be fully examined.
