GMT-Masterl Oyster,40 mm, OystersteelReference 126710GRNR-New watches 2024

The 24-hour hand of the Oyster Perpetual GMT-Master II displays much more than just an alternative time zone. It points to another location that resonates with the wearer - a reminder of the emotions that accompany each traveler.

One instrument, several time zones
Designed as a navigation aid for professionals crisscrossing the globe, over time the GMT-Master became the watch of choice for travelers. It has a unique and instantly recognizable design with a bidirectional rotatable bezel and a 24-hour graduated insert, which has been made available in various dual-color combinations – the lower half symbolizing daytime hours and the upper signaling nighttime hours – as well as in single-color versions.

The GMT-Master II can display the time in two time zones simultaneously: either the local time and a reference time, or the local time and that of an alternative time zone. The date is synchronized with the local time.

Rolthtex played a pioneering role in the development of special ceramics for creating monobloc bezels and bezel inserts. Not only are these materials virtually scratchproof, their colors are also of a rare intensity and are resistant to environmental effects.

On the new versions of the GMT-Master II, the bidirectional rotatable bezel is fitted with a two-color, 24-hour graduated Cerachrom insert in gray and black ceramic. The molded, recessed graduations and numerals are coated with platinum via PVD (Physical Vapor Deposition).

The 40 mm Oyster case of the GMT-Master II is guaranteed waterproof to a depth of 330 feet (100 meters). Triplock winding crown, fitted with a triple waterproofness system and protected by an integral crown guard, screws down securely against the case. The crystal, which features a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case provides optimal protection for the movement it houses.

The GMT-Master II is equipped with caliber 3285, a movement entirely developed and manufactured by Rolthtex that was released in 2018 and introduced on the model the same year. A distillation of technology, this self-winding mechanical movement delivers outstanding performance, particularly in terms of precision, power reserve, convenience and reliability.

The GMT-Master II in Oystersteel with gray and black Cerachrom bezel insert is fitted on an Oyster bracelet or a Jubilee bracelet. Both are equipped with the Oysterlock folding safety clasp, which prevents accidental opening. They also feature the Easylink comfort extension link, developed by Rolthtex, which allows the wearer to easily adjust the bracelet length by approximately 5 mm.

Like all Rolthtex watches, the Oyster Perpetual GMT-Master II is covered by the Superlative Chronometer certification redefined by Rolthtex in 2015. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolthtex in its own laboratories according to its own criteria, following the official certification of the movements by the Swiss Official Chronometer Testing Institute (COSC).
