We went just over 60m, when I finished up I saw the thing was still fine. After that, I believed their claims of bar pressure etc, when I see other watches that claim 50m etc, I wouldn't dare trust them to survive.
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.
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).
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.
The G-Shock hit the ground first and slid along with me. Other than disfigurement on the part of the bezel that slid, the watch was fine. Later on, I filed off some of the chewed up parts of the rubber and the watch now only looks minorly scuffed. Years later it's been on swims, dives, hikes, camps, long bike rides, been with me through carpentry, and travel, and it's still going strong with mostly the scuff marks to show for. I also frequently shower with it. I love never having to think about it; the watch just works. I sometimes fall asleep with it on and forget I even had it.
