The black dial is engraved with "MégaTapisserie" oversized plaid decoration, fluorescent platinum embedded hour markers and fluorescent RoyalOak hands (ask the black minute hand), the black tone rotates the inner bezel, and the black diving scale and area are from 60 minutes to 15 minutes.
Extended data:
Under water, you need to turn your wrist flexibly, whether you stroke your arm or operate an instrument. At this time, the watch needs to be tightly fixed on your wrist. Although many diving watches are equipped with metal watchbands, chemicals in seawater will slightly corrode them.
The part of the watch that enters the water is in the crown, because the crown is the only part that connects the outside world with the movement. In order to prevent water from entering the movement through the crown, the watchmaker developed a design called screw-in crown.
A waterproof apron made of rubber is added to the joint of the crown. When the crown is tightened, the water is tightly isolated from the watch (similar to the rubber pad at the water pipe valve in the family). There are also many diving watches to upgrade it and add deeper pit treatment on it.
