MORITZ GROSSMANN GMT – AT HOME IN TWO TIME ZONES
Model: Moritz Grossmann GMT White Gold Silver Dial MG-002155
Moritz Grossmann’s GMT timepiece presents an elegant watch of classic proportions with the added feature of two time zones. This function is in great demand among watch connoisseurs who travel extensively. A glance at the GMT provides orientation in different time zones to ensure its wearer is always in the right place at the right time.
Thanks to the discrete, functional design of the watch, the two time zones stand out clearly from each other.
– The centred 12 hour scale with baton indices shows the first time
– The second time zone is shown by a small arrow that runs around the outer dial on a 24-hour scale.
This separation allows its wearer to see different time zones and whether the second time zone is am/pm, at a glance
24-hour display with quick adjustment
The second time zone with 24 Arabic numerals is designed as an outer circumferential scale. A separate hand element, in compact arrow form, shows the respective hour. A separate setting crown at 10 o’clock allows the arrow indicator to be quickly adjusted in hourly increments both forwards and backward. The 12-hour display in the centre of the dial remains unaffected by this quick set function.
The 24-hour display is transmitted to the time zone ring via a complex system of gear wheels and always runs in accordance with the centre time. The 24-hour display also follows the 12-hour hand when the centre time is set using the crown.
The GMT is equipped with the calibre 100.8 in Moritz Grossmann’s high-artistic finish and the sapphire crystal back reveals the elaborately decorated mechanics of the calibre. It features the characteristic components of Moritz Grossmann movements such as: the 2/3 plate with the raised gold chatons, the Grossmann ratchet, the separately removable winding unit with pusher mechanism and the cantilevered balance cock with micrometre screw, as well as the mass-optimised balance.
On the GMT, the mechanism for the second time is integrated into the movement on the dial side. The 24-hour display is transmitted via the hour wheel of the centre time to another hour wheel and an intermediate wheel to the ring of the second time zone.
The second time zone display can be adjusted via the second crown at 10 o’clock. A ratchet wheel with ratchet spring is used to adjust the time in the pre-defined hourly gearshifts.
Dial and hands
The case is available in either rose or white gold. A dial in brilliant argenté emphasises the clarity of the design in the rose and white gold version. The white gold model is also available with an elegant dial in champagne tone adding a warmer colour accent. This version harmonises the massive rose gold case with the pristine aesthetic of the specially finished, sterling silver dial.
The 24-hour scale with blue Arabic numerals and matching arrow indicator stands out from the 12-hour scale in the centre of the dial and the unique lance-shaped hands provide Grossmann’s characteristic accent. The hands are handcrafted in the manufactory, finished and annealed in dark brown.
With the GMT model, the independent Glashuette manufactory is enriching its collection with a long-awaited time zone watch that beautifully reflects the very essence of its founder – the much-traveled cosmopolitan, polyglot writer and aesthete Moritz Grossmann. The clear design, advanced mechanics and superb craftsmanship represent Schönstes deutsches Handwerk (premium German craftsmanship) in a unique way and bear witness to the highest level of skill inherent in all Grossmann’s timepieces.
The elegant, clean appearance of the silver argente dial is enhanced by the beautifully polished, solid white gold case to deliver a subtle and dignified statement of style.
