Please remember that advertised depth ratings are conventions. 50 m water resistance means nowhere near 50 m down under. It’s a convention, an international system of classifying water resistance - you’ll find plenty of info on this on this forum, also on the seiko forum. Actually 50m means you can swim, shower, wash hands, and VERY shallow snorkeling. 100m WR just means increase a notch your dive depth.I've found that mechanical watches have as many myths and misconceptions posted online as cars do. Go to any car forum and read some of the posts on proper maintenance, things you shouldn't do, etc. I'm glad to see your refreshing posts on here and other forums dispelling rumors. The water resistance topic is one I'll never understand. Why people think that 50m means no water resistance is beyond me. 50m is 50m. That's a pretty decent amount of water resistance if you imagine being able to swim as far down as 50m.
Only if you go to “Divers” ISO standard you get proper dive depth WR, being it 150 or 200, or beyond.
With all that said, use it wisely and thoroughly, make it your daily companion, use it to check the freakin’ time (not the cell phone!), use the chrono, use it!
