I can see their QA issues on the internet; many have to do with service and lack there of. I can't find anything relating to failure to meet WR specs. Can you point to some reason not to take a SAN IV 500 M watch in the water or for that matter a Venom 1000 M watch? I specifically bought mine because I'm a boater and want water resistance.I love Invicta but even I wouldn't fully trust the depth rating on them. They have a history of poor QC, and there are too many horror stories online of the WR failing. I'm not a diver but I don't think any serious divers would consider using one. Deep Blue has a good rep in that area.
