126720 - THE OYSTER PERPETUAL GMT-MASTER II IN OYSTERSTEEL WITH AN OYSTER BRACELET.
This 126720 model features a black dial and a two-colour Cerachrom bezel insert in green and black ceramic. Designed to show the time in two different time zones simultaneously during intercontinental flights, the 126720 GMT-Master II has come to be recognized for its robustness and versatile appearance.
126720 - 24-HOUR ROTATABLE BEZEL
INNOVATIVE HIGH-TECHNOLOGY
In addition to conventional hour, minute and seconds hands, the GMT-Master II features an arrow-tipped hand, which circles the dial once every 24 hours, as well as a bidirectional rotatable 24-hour graduated bezel.
The 126720 distinctively coloured 24-hour hand displays the “home” reference time in a first time zone which can be read on the graduations on the bezel. The traveller’s local time is easily set by “jumping” from hour to hour, thanks to an ingenious mechanism operated via the winding crown: the hour hand can be adjusted forwards or backwards independently of the minute and seconds hands. This 126720 allows travellers to adapt to their new time zone without affecting the precision of their timekeeping. The 126720 Cerachrom bezel insert features an original colour combination: black and an exclusive green that is reserved for this model.
126720 - BLACK DIAL
HIGH LEGIBILITY IN ALL CIRCUMSTANCES
Like all Rolex Professional watches, the GMT-Master II offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Chromalight display. The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting glow.
On this 126720 novel version of the watch, the crown and crown guard are on the left side of the watch case. The date aperture and the Cyclops lens are at 9 o’clock.
126720 OYSTERSTEEL
HIGHLY RESISTANT TO CORROSION
Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.
THE 126720 OYSTER BRACELET
ALCHEMY OF FORM AND FUNCTION
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterlock folding clasp, which prevents accidental opening and the Easylink comfort extension link, also exclusive to Rolex. This ingenious system allows the wearer to increase the bracelet length by approximately 5 mm, providing additional comfort in any circumstance.
126720 - TWO TIME ZONES
SIMULTANEOUS DISPLAY
With traditional hour, minute and seconds hands, a triangle-tipped 24-hour hand, and a bidirectional rotatable bezel with 24-hour graduated Cerachrom insert, the GMT-Master II can display the time in two time zones simultaneously: either the local time and the reference time, or the local time and that of an alternative time zone. The date, at 9 o’clock on the dial, is synchronized with the local time.
126720 THE CYCLOPS LENS
A MAGNIFYING LENS
The 126720 Cyclops lens is one of the most distinctive Rolex features, and one of the most recognizable. Named after the one-eyed giant of Greek mythology, the Cyclops lens magnifies the watch’s emblematic date display two and a half times for easy reading. Behind the Cyclops, as with every feature of a Rolex timepiece, lies a history of invention, research and development, and the endless search for perfection.
126720 - 3285 MOVEMENT
SUPERLATIVE PERFORMANCE
The new 126720 calibre 3285, a new-generation movement entirely developed and manufactured by Rolex. With 10 patent applications filed over the course of its development, this movement features a Chronergy escapement and a guaranteed power reserve of approximately 70 hours. Like all Rolex Perpetual movements, the 3285 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 3285 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.
On this 126720 watch, the crown and crown guard are on the left side of the watch case. The date aperture and the Cyclops lens have also moved and appear at 9 o’clock. This 126720 required several technical adjustments in terms of the movement and the Superlative Chronometer certification, for which the protocol, as well as some of the final tests, had to be adapted.
