The consensus among most diving professionals (equipment repair techs, diving instructors, commercial divers, etc.) is that for actual sport diving (above 130 feet/40 M / 5 BAR), a watch should have a minimum rating of 200 meters. While this may seem excessive, there's more going on than just the "static pressure" of the water at any given depth. Any movement creates additional "dynamic pressure" Add to that seals that may not be brand new, sand, salt, and the overall SCUBA philosophy of water being an alien environment thus necessitating a bit of redundancy and we get to the 200M minimum rating.
