The Rolex Sky-Dweller in Oystersteel and white gold with a bright blue dial and a Jubilee bracelet. A fixed inverted red triangle on the dial points to the chosen reference time – the time at home or at the traveler’s usual workplace – on the off-center 24-hour disc. At a glance, this 24-hour display clearly distinguishes daytime hours from night-time hours in the other time zone.

A deep red rectangle in one of the 12 windows around the dial indicates the current month, a striking characteristic of the Saros annual calendar. This ingenious mechanism simplifies life for the wearer of the watch, who no longer needs 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 needed – on 1 March (February having only 28 or 29 days). The date is connected to local time and automatically changes according to the traveler’s local time zone.

The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case, helping to ensure the waterproofness of the watch. It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, always in gold. The Sky-Dweller is equipped with a mechanism of interaction between the rotatable bezel, the winding crown and the movement: the Ring Command system, which allows the user to select the watch’s functions one-by-one and to set them easily, quickly and securely.

Supple and comfortable, this five-piece link metal bracelet was specially created for the Oyster Perpetual Datejust, which was launched in 1945. The Jubilee bracelet on these watches is equipped with a folding Oysterclasp and features the Easylink comfort extension link, developed by Rolex, which allows the wearer to easily adjust the bracelet length by approximately 5 mm. The bracelet also includes patented ceramic inserts – designed by the brand – inside the links to enhance its flexibility on the wrist and its longevity.
