I did swim with a snk809 and did multiple small dives (3-4m) with a digital Casio, both labeled to resist 30m. No issues whatsoever. If the watch is under 5 years of age i think most of us can’t dive to a depth that would damage them.
I know a guy that regularly swims with a Speedmaster (older model), so I think most of us are exaggerating with depth rating. We should just be careful to have the crown screwed / pushed, consider gasket age after 5+ years, and enjoy our watches without fear.
A black rubber would so just fine on it.
Yes because in the dresser it was placed in a position it runs well. Try putting it in the dresser but with crown down or another position you use during the day and you will see a variance.
That’s what the 6R movement does… try demagnetizing it but it sounds like a typical 6R inconsistency. It’s mainly caused by positional variance & low amplitude. Had some inconsistencies on spb143 and just returned a new spb335 (with the same movement) for running -38 s / day.
Watch brands also want to be safe and usually put a lower rating on a watch, even if it can do more.
