Mechanism: Calibre 3186 is a self-winding mechanical movement entirely developed and manufactured by Rolex. In addition to the conventional hour, minute and seconds hands, it features a 24-hour hand to display a second time zone.

Like all Rolex Perpetual movements, the 3186 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The 3186 is equipped with a Parachrom hairspring, offering greater resistance to shocks and to temperature variations. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.

Family Notes: Although the Rolex GMT-Master was designed essentially for professional use, its combination of peerless functionality and rugged good looks has attracted a wider travelling public. As well as appreciating its ability to display different time zones, these travellers admire the robustness and versatile appearance that make the GMT-Master eminently suitable for globetrotting and, indeed, for any occasion.
