The bidirectional rotatable bezel is fitted with a two-colour, 24-hour graduated Cerachrom insert in green and black ceramic that was never used before on this model. The moulded, recessed graduations and numerals are coated with platinum via PVD (Physical Vapour Deposition). The green half symbolises day-time while the black signals night-time.
Just like the crown, the date aperture and the Cyclops lens fitting the antireflective sapphire crystal have also moved and appear at 9 o’clock buy replica watches. This 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.
Thanks to the traditional hour, minute and seconds hands, the additional 24-hour hand, and the rotatable bezel, it is possible to read the time in two time zones at once: either the local time and a reference time, or the local time and another time zone as desired. The date, shown at 3 o’clock, is synchronized with the local time display.
The watch is powered by the in-house designed and manufactured self-winding Calibre 3285 which is equipped with a Chronergy escapement made of nickel-phosphorus (insensitive to magnetic fields) and guarantees a power reserve of approximately 70 hours. The blue Parachrom hairspring is made in a paramagnetic alloy that makes it up to 10 times more precise than a traditional hairspring in case of shocks.
Rolex introduced an unexpected version of its Oyster Perpetual GMT-Master II characterised by a green and black bezel and, more importantly replica tag heuer watches, by the crown and its guards positioned on the left side of the case.
Crafted from Oystersteel, a particularly corrosion-resistant steel alloy, the 40 mm Oyster case of the new GMT-Master II 126720VTNR is guaranteed waterproof to a depth of 100 metres / 330 feet), also thanks to the Triplock winding crown that screws down securely against the case. The case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement.
