The Rolex Oyster Perpetual GMT-Master II has established its position as a reliable companion for professional pilots undertaking long-distance flights since its inception in 1955, and today it is an essential item for global travelers active around the world. This model features an independent 24-hour hand and a bi-directional rotating bezel with a 24-hour scale, allowing for the simultaneous display of a second time zone. The functionality that enables one to grasp the local time at the travel destination and the time at home at a glance transcends mere timekeeping, becoming a symbol of the emotions that connect different places. All models have obtained Rolex's unique highest standard certification, the "Superlative Chronometer," ensuring exceptional accuracy and reliability.
- Two times, one watch:
By combining an independent 24-hour hand with a bi-directional rotating bezel, it allows for instant reading of the local time and another time zone (home time or a third time zone). The cleverly independent adjustment hand allows for time adjustments without affecting the progress of the minute or second hands, featuring practical high functionality.
- Timeless beauty: Cerachrom ceramic bezel
The 24-hour scale bezel made of Cerachrom ceramic, developed exclusively by Rolex, is highly scratch-resistant due to its high hardness and has extremely high resistance to fading caused by ultraviolet rays. The iconic two-tone colors (green-black, blue-red, brown-gold, etc.) visually distinguish between day and night time periods.
- Evolving high-performance movement: Caliber 3285
Introduced in 2018, the Caliber 3285 perpetual automatic movement equipped in the GMT-Master II is entirely developed in-house by Rolex. It incorporates patented technologies such as the Chronergy escapement and Parachrom hairspring, enhancing accuracy, magnetic resistance, and shock resistance. It achieves approximately 70 hours of power reserve.
- A symbol of robustness: Oyster case
The Oyster case, carved from a solid block of material, boasts high airtightness and robustness. With a screw-down crown and case back, along with sapphire crystal glass, it achieves a water resistance of 100 meters, protecting the movement in all environments.
- Proof of exceptional accuracy: Superlative Chronometer certification
The "Superlative Chronometer" certification set by Rolex means that in addition to the movement being tested by COSC (Swiss Official Chronometer Testing Institute), it has passed Rolex's own rigorous final tests when incorporated into the case. The accuracy in the wearing state is guaranteed to be within an industry-leading performance of -2/+2 seconds per day.
