The Ultimate Guide to Waterproof Watches

A water-resistant watch is a must-have for swimmers, divers, and campers who want a dependable timepiece in the water. But not all “water-resistant” watches are created equal—their longevity varies based on water resistance ratings (expressed in ATM, meters, or BAR).

1. Water Resistance Ratings Explained
Rating\tWithstands\tSuitable For
3 ATM (30m)\tRain, handwashing\tDaily wear (not swimming)
5 ATM (50m)\tShower, light swimming\tCasual water exposure
10 ATM (100m)\tSwimming, snorkeling\tWater sports
20 ATM (200m+)\tScuba diving\tProfessional divers
Diver’s Watch (ISO 6425) Deep-sea diving Certified for extreme depths
⚠️ Note: No watch is 100% “waterproof”—only “water-resistant.” Always check the manufacturer’s limits.

FAQs
❓ Showering with a 50m water-resistant watch?
→ Yes, but use soaps/shampoos that don’t damage seals.

❓ Which is best: 100m or 200m?
→ 100m = swimming | 200m+ = diving
