Rolex Oyster Perpetual Sky-Dweller

Partially verified

This Rolex Oyster Perpetual Sky-Dweller wristwatch features an 18K yellow gold case measuring 42mm in diameter. The timepiece is fitted with a black dial displaying an off-center 24-hour disc for home time, local time indices, and a Cyclops lens magnifying the date at 3 o'clock. Twelve discrete apertures around the dial perimeter indicate the month. The movement is the self-winding Rolex Calibre 9002, which provides approximately 72 hours of power reserve. The fluted 18K yellow gold bezel acts as the Ring Command interface for setting calendar and time functions via the crown. The watch is worn on a black Rolex Oysterflex bracelet composed of metal blades encased in elastomer, secured by an 18K yellow gold Oysterclasp with a Glidelock extension system.

Object description

Case and Dial Design

The watch is housed in a 42mm case constructed from 18K yellow gold. It features a fluted bezel that functions as a Ring Command interface, which allows the wearer to adjust calendar and time zone settings using the winding crown. The black dial is configured with an off-center 24-hour disc used to track home time, while the main hands indicate local time.

A Cyclops lens is positioned over the date aperture at the 3 o'clock position to provide magnification. The month is displayed through twelve discreet apertures arranged around the periphery of the dial, marked with red indicators to distinguish the current month. The watch utilizes an Oysterflex bracelet, which is constructed from flexible metal blades covered in black elastomer, terminating in an 18K yellow gold Oysterclasp that includes a Glidelock extension system.

Evidence for this section
  • “The fluted yellow gold bezel also serves as the Ring Command interface”
  • “Its bright black dial is arranged around an off-center 24-hour disc”
  • “Twelve discreet apertures around the dial indicate the month in red”
  • “Rolex's Oysterflex bracelet combines flexible metal blades with black elastomer”

Movement and Functionality

The timepiece is powered by the self-winding Rolex Calibre 9002 movement, which offers a power reserve of approximately 72 hours. This movement drives the annual calendar, which is a patented system known as the Saros calendar, introduced in 2012.

The Saros system is designed to automatically distinguish between months with 30 days and 31 days. Consequently, the user only needs to manually adjust the watch once per year, specifically on March 1st. The movement manages both the date display and the dual-time zone function displayed on the central disc.

Evidence for this section
  • “The self-winding Calibre 9002 provides approximately 72 hours of power reserve”
  • “Introduced in 2012, the Sky-Dweller debuted Rolex's patented Saros annual calendar”
  • “which automatically distinguishes 30- and 31-day months and requires adjustment only once each year, on March 1.”

Included Accessories

These accessories accompany the watch as part of the complete set as described by the vendor.

The bracelet is finished with an 18K yellow gold clasp, which is stamped with the Rolex crown logo, Geneva, and Swiss Made, along with the Au750 hallmark indicating the gold fineness.

Evidence for this section
  • “The watch is accompanied by its original Rolex box, warranty card and booklet.”
  • “18K yellow gold Oysterclasp equipped with the Glidelock extension system”
