After having launched a ‘sky diving friendly’ GMT Sport with Integrated Bracelet earlier this year, Greubel Forsey have now announced the third and final variant of its GMT Earth. The first was in white gold, the second in platinum, and this new variant is in titanium, with black finishing.
The titanium case is 45.5mm with a thickness of 18mm, and has a water resistance of 50m. The use of titanium extends to the plates, which are engraved and, hand-finished.
Under the domed sapphire crystal, is the familiar dial – as well as the time, small seconds, and a power reserve, it has a GMT second time zone, a rotating globe with Universal Time/ twenty-four time zone, summer/ winter time indication, and day/ night indications.
You can get a more complete view of the globe through a window at the side of the case. It makes a complete (anti-clockwise) rotation every twenty-four hours.
Powering all of this is a manually-wound movement that beats at 21,600 VPH and has a power reserve of 72 hours. It features a tourbillon inclined at a 25 degree angle with 1 rotation in 24 seconds.
Material-wise, the multi-level hour-ring is synthetic sapphire, the minutes and small seconds are engraved and lacquered. The power reserve and GMT indicators are in gold and also engraved and lacquered, with circular graining and black treatment. The engraved rotating globe is synthetic sapphire and lacquered.
As mentioned a couple of months ago, Greubel Forsey announced that it will eliminate the use of animal leather in its straps as of 1 January, 2022, when they will be all plant-based materials. Limited to eleven pieces, this new GMT Earth Final Edition comes on a rubber strap or a hand-sewn alligator leather strap, both with a titanium folding clasp.
It’s worth remembering that there was a limited edition (22 piece) GMT Black in a ADLC-treated titanium case released in 2015.
