In general, a dive watch (AKA diving watch, or diver’s) is a watch designed for can stand at the least 100m(330ft) seawater's pressure. Most people who buy dive watches are in fact not divers at all, and many professional SCUBA divers are no longer wear a dive watch anymore during the diving process.
We believed one of the main reason people love dive watch is because of the tough appearance. Some people may be attracted by the intricate engineering structure.
If you need a watch that can handle any environmental conditions without any worries, a dive watch is probably for you.
Characteristics of the Modern Diver’s Watch
• A unidirectional (rotates in only one direction) bezel with elapsed time markings at least every 5 minutes.
• Clearly distinguishable minute markings on the watch dial.
• Ability to be read from a distance of 25cm (10in) in total darkness (requires luminous markers of some kind).
• A visible indicator that the watch is running, that can be seen in total darkness. This is usually implemented using a running second hand with a luminous tip.
• Solid strap or band, with the attachment point able to withstand a force of 200N (45lb/ft).
• Battery powered watches must include an End of Life (EOL) indicator.
In addition to being water resistant, dive watch cases must be able to resist the corrosiveness of seawater. Usually cases are made from stainless steel, titanium, ceramics, or plastics.
The case has to be built stronger and more durable than a dress watch. Because of this, dive watches are relatively large and heavy, compared to other watches not built to withstand the same level of rugged use.
Dive watches use the same range of different materials for the crystal as other watches, but a dive watch crystal will be relatively thick in order to withstand water pressure.
Domed crystals are often used to provide extra strength, while also reducing the reflectiveness of the crystal, allowing it to be easier to read. These can induce some distortion in the view of the dial however. Personally, I love the look a slight dome gives to the watch.
While several methods have been used to waterproof the winding and adjustment mechanisms, a screw-down crown is the most common.
With a screw-down crown, the crown screws into the case, sealing the interior of the watch and preventing accidental adjustments. Before the watch can be wound or the time adjusted, the crown is unscrewed, and then pulled out to adjust.
Hopefully you have a good understanding of features you should be expecting and looking for in a diver’s watch after you read this article.
