2025 NEW GMT-Master II Oyster, 40 mm, white gold Reference 126729VTNR

The Oyster Perpetual GMT-Master II in 18 ct white gold with a green ceramic dial and an Oyster bracelet.

 

This model features a green ceramic dial and a two-colour Cerachrom bezel insert in green and black ceramic. 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 Cerachrom dial – created in the same way as dials in natural stone, by fitting a disc of material onto a brass plate – displays the same shade of green as the lower half of the two-colour green and black Cerachrom bezel insert that frames the watch face. It is the first Cerachrom dial on a Rolex watch.

 

On this 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.

From the exterior, not much has changed other than the material for the latest GMT-Master II adaptation. Obviously, exchanging Oystersteel for white gold significantly ups the weight, but the dimensions and proportions remain the same. That comes down to a diameter of 40mm and a height of 11.90mm for the case, with a bidirectional rotating bezel in white gold and black and green ceramic. So far, so good.

The dial, however, changes from lacquered gloss black to green Cerachrom, tying the exterior with the interior, as it matches the lower half of the bezel insert. For the rest, we still see applied white gold hour markers and hands with Chromalight inserts. The additional GMT hand now has a white/steel coloured stem instead of a green one, which would otherwise blend into the background.

The movement has been left untouched, as it is perfectly able to perform as it should. Running at a rate of 28,800vph, the Calibre 3285 is fitted with a Chronergy escapement and a Parachrom hairspring. It is of course COSC-certified as a chronometer, even though Rolex’s own Superlative Chronometer certifications surpasses the COSC standards. The movement has a running time of 70 hours in total.
