Rotary ring can be said to be one of the important characteristics of the diving table, to remind the diving time.
The mark scale of the rotating bezel is 15, 30, 45, because the scuba tank can only last 45 minutes, and some are marked 60 minutes.
The first 15 minutes are colored or marked, and divers strictly observe a 15-minute safety stop during ascent to fully release the nitrogen absorbed from the cylinder.
Usually, YOU CAN TELL the dive TIME BY TURNING the DIAL SO THAT THE 0 scale ON THE DIAL is aligned with the minute hand, and then looking at the dial on the corresponding dial after the minute moves.
Oyster constant motion Marine 4000-904L stainless steel watch.
Rolex has unveiled a modern version of its Oyster constant motion Marine watch, bringing back the legendary diver’s watch that was first introduced in 1967.
The 40mm technical diver watch can reach depths of 1,220 meters (4,000 feet) and uses innovative Rolex technology and equipment,
They included Cerachrom ceramic word rings, Chromalight luminous materials that glow for a long time, paramagnetic blue Parachrom springs, Oyster clasps and Rolex Glidelo strap extensions.
A countdown reminder is crucial for divers because of oxygen constraints, which can cause decompression sickness if they come up too fast due to a shortage of oxygen.
Therefore, the rotary bezel is a very ingenious and practical function.
The rotation of the outer ring is designed as a single counterclockwise direction, and now the latest design uses a safety switch to control the arbitrary rotation and locking of the ring.
The latest market dynamics at any time to see, please pay attention to.
