During these last few decades, diving watches have seen some changes. Many of the changes have been style oriented, and tailored more for desk divers, but some of the changes have been meaningful. Every dive watch is designed to tackle at least some form of diving. Some are more for the style of it all, but others are quite serious about deep diving and scuba. Therefore in this article i will talk about what it means to be a dive watch, and what is best o look for when pondering buying one.
In the beginning when considering a dive watch, the buyer should pay close attention to the depth of water resistance the watch offers. For most dive watches, 100 meters and 200 meters are basically standard levels of water resistance. This mean the resistance at static water pressure levels tested in a lab. Most diving agencies make sure the casual diver does not go beyond 130 feet deep. 100 meters is 328 feet plus, and that is plenty of protection for standard casual diving situations. The biggest danger to a mechanical watch is moisture from the outside of the case.
It can cause the ever important movement to become eroded. In an effort to prevent such damage, many watch makers supply the watch with a screw down crown. This requires the owner to screw the crown in or out to gain access, and the protect the interior. Some believe screw down crowns and casebacks are a hassle, but they are a very good idea to avoid the possibility of water finding its way inside the watch. Screw down capability also protects the watch from other elements like dust and dirt. So make sure the watch you buy at least is made from a high quality stainless corrosion resistant level of steel.
Another aspect to a good dive watch is that rotating bezel, which on a good dive watch, will be unidirectional most of the time. Having the bezel be unidirectional helps to avoid mistakes being made when measuring time relevant to how much gas remains in the divers tank. The rotating bezels are somewhat obsolete now because modern diving computers take care of all that, but its is still a nice feature to have on the dive watch, and is appreciated by more mature, old school diving enthusiasts.
Lastly we should should touch on the importance of a good watch strap or bracelet for your dive watch. In water, a rubber strap is best, or you could go with a stainless steel bracelet. Such steel is easy to clean, and quality rubber requires little to no maintenance at all. In some cases you could get away with using a nylon strap, but they have a tendency to acquire an odor over time, and some of them do not feel quite dry after taking a dip. I would only use a leather strap if the watch was for casual wear only. I hope this article was of use to you, and thanks for reading. Take care, and ave a great next dive.
