When it comes to the waterproofness of your watch, you should almost never take the numbers on the dial or case back literally.
For example, a watch with 30 metres water-resistance can sustain a light shower or splash, but you shouldn’t swim in it. Likewise, you won’t want to dive wearing a watch with less than 200 metres water-resistance, even if you’re not planning on diving to anywhere near that depth. Here’s a handy scale to help guide you.
0 to 30 metres = Not suitable for any contact with water
30 metres = Splash-proof (ex. washing hands and rain droplets).
50 metres = Light poolside swimming
100 metres = Swimming, Snorkelling
200 metres = Scuba Diving
300 metres and up = Professional Diving
Water-Resistant seals don’t last forever, particularly if you get your watch wet regularly. We recommend getting your watch reproofed every one to two years, depending on usage.
