Blaken owners are people who are not superficial, but who possess depth. Such as sport divers, for example. The water and high pressure resistance is not just a standard technology - it is cutting edge.
The Oyster Perpetual Rolex Submariner sets global standards in this regard. Almost every technical detail - from the rotating bezels to the clasp, the winding crown and the oyster housing right down to the Cerachrom bezel - has been developed for diving down to 300 meters depth.
As a result, this fantastic watch is also great for everyday use and is waterproof in the pool and under the shower.
