THE 3285 MOVEMENT
The new 3285 caliber is a new generation movement entirely developed and produced by Rolex, the subject of ten patents and equipped with the Chronergy escapement to guarantee a power reserve of around 70 hours. Like all Rolex Perpetual movements, the 3285 is a certified Swiss chronometer, a title reserved for superior precision watches that have successfully passed COSC tests ( Contrôle Officiel Suisse des Chronomètres ). The 3285 caliber includes a Parachrom spiral that guarantees better resistance to shocks and temperature variations. The architecture, which unites it to all the movements in the Oyster collection, gives it an unparalleled reliability.
24-HOUR ROTATING BEZEL
To complete the traditional hour, minute and second hands, the GMT ‑ Master II exhibits an additional hand that turns the dial in 24 hours, as well as a 24 hour graduated bidirectional rotating bezel. This 24-hour hand with an intense color indicates the reference time of a first time zone of origin, readable on the graduation of the bezel. When traveling, the local time is indicated on the dial by the traditional hour hand which can be easily adjusted, by jumping for an hour, thanks to a mechanism controlled by the winding crown. Local time adjustment takes place independently of the minute and second hands. This allows travelers to adjust the new time zone without having to compromise on the accuracy of their watch.
