ROLEX Sky-Dweller RO1627

 Rolex Sky Dweller "The Most Complex Rolex Watch in History"

The 42mm oyster shaped case is polished with 904L stainless steel, and the bezel is made of Rolex Ring Command triangular groove bi-directional rotating bezel. The rotating outer ring can adjust the month function. The watch buckle is a foldable oyster style buckle with a 5MM adjustable chain link extension system.

The 9002 movement exclusively modified by ZF has 28800 oscillations per hour. The power reserve reaches 72 hours. The correct calibration method consistent with the genuine product is in the second time zone, where Sky Dweller is displayed through a sub dial. It consists of two elements: a red triangle located below the logo, which points to the time in the second time zone and is displayed in 24-hour format. Rotate the head and pull it out to the first gear. If it goes up, it will adjust the calendar gear. If it goes down, the hour hand will become monotonous (the minute hand remains stationary). Pull to the second gear to adjust the time normally (the 24-hour watch circle on the sub dial moves accordingly)
