I've taken several watches on dives just to see if the ratings are real.
Timex Easy Reader, says 30m, failed on a dive that was no more than 15m.
Seiko SKX-007 OTOH, rated to 200m, I have taken it to about 30m with no ill effect.
I've since learned you can have a watch repair shop test this with a pressure chamber and a finely-calibrated displacement-measuring instrument, no water required.
- Sekhmet 3y agoWater resistance ratings of 30 meters don’t mean that you can dive with it up to 30 meters. Those ratings are related to static pressure tests. Generally 30 meters shouldn’t be submerged, 50 meters is okay for swimming, above that diving is acceptable to certain limit. True diving watches start with 200 meters and preferably ISO diver's certification (which SKX has).
- CydeWeys 3y agoThe funny thing about the 200m WR rating on true diver's watches is that that's more than even 99.9% of divers are ever going to use. Recreational diving tops out at 40m (that's a deep dive!), let alone 200m. The actual number of people diving to deeper than that in an entire year, worldwide, is a 3 digit number. Of course I say all that and yet I have a Seiko spring drive tuna 600m saturation diver, even though it's never been deeper than a few meters and very unlikely ever to do so. But the engineering is fun to appreciate even if it'll never do even 1% of what it's capable of.
