Rolex Sky-Dweller: Oyster, 42 mm, Everose gold, Chocolate dial, m336235-0002

The fluted bezel of a Rolex watch is a distinguishing feature. Originally, the Oyster bezel’s fluting served a practical purpose, helping to ensure the watch’s waterproofness. It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Eventually, the fluting became an aesthetic element, a true Rolex signature feature. Today, the fluted bezel is a mark of distinction, always in gold. The Sky-Dweller is outfitted with a mechanism of interaction between the rotatable bezel, the winding crown, and the movement—the Ring Command system—that enables the user to quickly and easily select each function one at a time.

One of the most notable features of the Saros annual calendar is the fixed inverted red triangle on the dial, which points to the chosen reference time (the traveler’s usual workplace or place of residence) on the off-center 24-hour disc. At a glance, this 24-hour display clearly distinguishes daytime hours from nighttime hours in the other time zone. The wearer’s life is made easier by the brilliant mechanism, which eliminates the need to think about adjusting the date at the end of a 30-day month. The annual calendar displays the correct date throughout the year; only one adjustment is required, on 1 March (February having only 28 or 29 days).
