Magnificent Dual Time Zone with Saros Annual Calendar

Gorgeous Black Dial and Oyster Bracelet

As one of the best designs in this legendary watchmaker’s line, the Rolex Sky Dweller in 18kt White Gold has a keen reputation to live up to. It does not fail to deliver. This stunning timepiece marries Rolex precision and quality with an incredibly clean and classic appearance.

Aimed at frequent fliers and powered by the latest caliber 9001 movement, the Rolex Sky-Dweller boasts 14 patents. Local time is displayed with central hands, while home time is indicated by a red arrow pointing at an hour number on the aforementioned rotating disc. The rotating Ring Command bezel allows you to easily set local time, home time, and date with a twist in either direction.

Of particular interest is the annual calendar that requires adjustment only once per year on March 1. Rolex named the innovative calendar mechanism Saros after the cycle of
alignment patterns between the sun, earth, and moon that produces lunar and solar eclipses. The mechanism is based on a fixed planetary gear wheel with an orbiting satellite wheel that is fitted with four fingers, one for each 30-day month. The satellite wheel orbits the planetary wheel once per month, and at the end of a 30-day month, the finger
triggers the calendar disc to jump twice within a few milliseconds to advance from the 30th to the 1st. Months are indicated with apertures positioned at each corresponding hour marker around the dial’s periphery. In January, for example, the window positioned at 1 o’clock  displays the color black. ~ Courtesy of Forbes.com
