24 hour rotating bezel
In addition to the traditional hour, minute and seconds hands, the GMT-Master II features an arrow-shaped hand that circles the dial every 24 hours and a bi-directional rotating bezel with a 24-hour scale.
black dial
Like all Rolex Professional watches, the GMT-Master II boasts excellent readability in all conditions, especially in darkness, thanks to its Chromalight display. The wide hands and hour markers in simple shapes such as triangles, circles and rectangles are made from a long-lasting luminous material that emits blue light.


oyster steel
Oystersteel is used for the cases of Rolex steel models. Oystersteel belongs to the 904L steel family and is most commonly used in the high tech, aerospace and chemical industries where maximum corrosion resistance is essential. Oystersteel is extremely durable and polishes well. It retains its beauty even in the harshest of environments.

About product inventory
All Rolex watches are meticulously hand-assembled to ensure exceptional quality. To maintain our high standards, production is limited and sometimes demand exceeds supply.
Therefore, some models may have limited stock. New Rolex watches are only available from authorized Rolex retailers who regularly supply and manage their sales to our customers.
As an Authorized Rolex Dealer worldwide, Lexia welcomes inquiries about the availability of Rolex watches.
Introduced in 1955 and designed to simultaneously display the time in two different time zones, the GMT-Master was originally developed as a navigation device for professional pilots flying around the world. In 1982, the Oyster Perpetual GMT-Master II, equipped with a new movement and improved usability, appeared as the successor to the first model. Its unparalleled functionality, robustness, and instantly recognizable design have fascinated people traveling the world.
