A dive watch is exactly what it sounds like. These are one of the more popular kinds of watches because of a few reasons. One is that is looks great! Dive watches are attractive, as they usually have bracelet straps, simple clean dials and good looking cool bezels. Specifically designed and created for underwater diving, a dive watch features water resistance (to an extent) so that you're able to go under safely. One of the main features of a dive watch is it should have a waterproof case. The rotating bezel of a dive watch is another key feature. Dive watches are generally tougher than other watches. The range of the water resistance of each watch is different, but it is typically around 200-300 m. In 1926, Rolex debuted the first water-resistant case with its patented Oyster case.
