O-rings are used to seal the crown, caseback and crystal. In nearly all dive watches, the case has a screw-in back and crown. Several features are required to make a watch impermeable enough to wear diving. What features make a watch impermeable enough for diving?
All these imponderables cause the companies to provide a rather large cushion of safety so that customers will not hold them responsible if their watches leak.Ī screw-in crown is essential to a watch’s water resistance. Knocks and other rough treatment can cause the case’s components to fit together less tightly than they did when the watch was brand new. Furthermore, a watch’s water resistance will be lessened by aging of the watch’s gaskets. The testing machinery does not account for such phenomena as additional pressure from the impact of the wearer’s jumping or diving into the water or for temperature and pressure changes as the diver ascends and descends, which can cause the case to shrink or expand. For the test, the watch is perfectly stationary, the gaskets brand new, and the case newly assembled, so that nothing will compromise its water resistance. The reason for the discrepancy: when tested for water resistance in the factory, the watch is in an artificial environment that is much different from what the watch will face during an actual dive. Beyond that, they enter the realm of technical diving, which requires extensive training, special mixed gases to breathe, long decompression stops and special equipment. Recreational divers don’t go deeper than 40 meters (130 feet). The International Standards Organization (ISO), on the other hand, stipulates that a dive watch must be water resistant to 100 meters.Īll these depth ratings are significantly higher (or lower, if you will) than the depths to which a non-professional diver can dive.
Others say the watch need have a rating of just 200 meters still others say it can be 200 meters as long as it is specifically labeled as a dive watch. Some manufacturers say that their watches with a water-resistance rating of 300 meters or more are suitable for recreational scuba diving. How water resistant should a dive watch be?
