Rolex has earned its place as the unofficial king of watchmaking. No other brand regardless of how long they have been making watches; or their technical prowess can stand next to Rolex as a competitor for sheer notoriety. This is evidenced by the effortless class of the Oyster Perpetual GMT Master II.
The GMT Master II has been used extensively by pilots and jet setters around the world who need to keep track of multiple time zones. This watch has a very rich heritage as revealed during the test flights of the Concorde when British and French test pilots, Brian Trubshaw, and Andre Turcat, both wore GMT Masters.
This Rolex Oyster Perpetual GMT Master II has a case which has been crafted from a single block of stainless steel. The case carries dimensions 40mm in diameter. The case also has a polished out cropping of stainless steel which protects the ridged crown from impacts.
The bezel is made from Cerachrom and features a 24 hour display which can rotate in either direction. Each rotation covers one hour and is set negating the possibility of an intermediate stop. Cerachrom is used as it has excellent anti-corrosion properties and will not fade over time. The most striking feature on the bezel is the blue and black color variations which serve to differentiate between night and day for the second time zone function.
The dial on this model is black and features luminous indexes and Rolex hour and minute hands. GMT stands for Greenwich Main Time and normally signifies a second time zone. With the Oyster Perpetual GMT Master II, three time zones are possible. At the 3 o’clock position there is a date aperture with a convex magnifying lens ensuring readability.
Ensuring that this watch remains accurate is a COSC certified chronometer self-winding mechanical movement. To gain COSC certification watches must undergo a battery of tests in which the daily variation does not exceed -4/+6 seconds. The balance wheel beats at a high frequency of 28,800 VpH allowing this watch to time smaller intervals of seconds guaranteeing precision over time.
This watch uses the famous Oyster three-piece link system which is ultra-comfortable due to the smaller links which contour around the wrist. Securing the bracelet to the watch is a single folding deployant clasp. Sapphire crystal is used defending the dial against the elements.
