Rolex GMT Master II Ultimate Guide

Since its unveiling in 1982, Rolex GMT-Master II has been the cosmopolitan watch that combined functionality and aesthetics. This classy timepiece features a design that simultaneously shows two time zones.

Thanks to its robust and peerless beauty, Rolex Collection is a favorite to professionals traveling across the world.


You can recognize the Rolex GMT-Master II because of the distinctive two-color bezel. The cerachrom insert on the watch comprises high-tech ceramic, a product of Rolex’s pioneering spirit.

The bezel is bidirectional and has 24-hour calibrations, divided into day and night hours. Initially, the cerachrom insert was available in blue and red, but more colors are available today.

The Rolex GMT-Master II, 18ct white gold timepiece, features a dial made from a rare iron meteorite.


1. It displays time from two time zones

The most noticeable feature of the Rolex GMT-Master II is the two-color cerachrom insert. This feature allows travelers to tell the time of two different time zones simultaneously. The timepiece uses its hour, minute, and second arms, alongside the 24-hour graduated insert, to display time from two time zones.

It also has an arrow-tipped hand that circles the dial in 24 hours. The GMT Master II also has a distinctively colored hour hand, with “home” inscriptions for the user’s reference.

Interestingly, the cerachrom bezel is one piece of ceramic, not two joint pieces. Only Rolex has the technology to produce this type of ceramic with its unique, patented process.

2. Rolex Caliber 3285

Rolex GMT-Master II features caliber 3285 movements. The self-winding mechanical movements are so that they offer the perfect precision and convenience. Furthermore, the watch becomes resistant to magnetic fields and shocks.

So, you do not need to keep calibrating your watch. The caliber 3285 can also store power for up to 70 hours.

The caliber 3285 allows Rolex GMT-Master II owners to adjust to local time without touching the 24-hour hand or stopping the watch. They achieve change by rotating the bidirectional winding crown.

3. Oyster bracelets

The Rolex GMT-Master II is a Swiss-certified chronometer that features oyster cases and bracelets. The Everose Rolesor and 18ct gold Rolex GMT-Master II have three-piece link oyster bracelets.

The Oyster Steel Rolex GMT-Master II comes in a 5-piece jubilee or oyster bracelet. The jubilee bracelets are particularly famous for their suppleness and comfort.

4. Safety Clasp

Rolex employs the best measures to keep your watch for as long as possible. Part of their safety measure is an Oysterlock safety clasp. This feature, present in the Rolex GMT-Master II Oyster and Jubilee bracelets, prevents your watch from accidentally opening.

If you need to resize your Rolex GMT-Master II, you can do so through the Easylink rapid extension system. This feature allows anyone wearing the timepiece to increase the length by up to 5mm for more comfort.
