Rolex Sky-Dweller: 42 mm, Everose gold with a blue-green dial and an Oyster bracelet, m336935-0001

One way to identify yourself is with a Rolex fluted bezel. The Oyster bezel’s fluting originally served a practical purpose, allowing the bezel to be screwed into the watch case and assisting in ensuring the watch’s waterproofness. Thus, it was the same as the fluting on the case back, which was likewise secured to the case with special Rolex tools in order to make it waterproof. With time, the fluting evolved into a defining visual component and authentic Rolex trademark. The fluted bezel, always in gold, is a symbol of distinction in modern times. The rotating bezel, winding crown, and movement of the Sky-Dweller are all connected by a mechanism called the Ring Command system, which enables the user to choose and swiftly set each function of the watch individually.

The selected reference time, which can be the traveler’s regular work place or their home, is shown by a fixed, inverted red triangle on the dial, which is located on the off-center 24-hour disc. This 24-hour display makes it easy to tell when it is daytime in the other time zone and when it is nighttime. One notable feature of the Saros annual calendar is the deep red rectangle that shows the current month in one of the twelve windows surrounding the dial. The clever mechanism of the watch makes life easier for the wearer by eliminating the need to think about changing the date at the conclusion of a 30-day month. The accurate dates are shown throughout the year on the annual calendar. There is only one modification required, which is on March 1 (February has only 28 or 29 days).
