After a decade, the Greubel Forsey GMT Earth has reached its Final Edition. This latest and final edition is now in a titanium case with an intense black finish. Limited Edition of 11 pieces.
Commentary
We covered the early editions of the GMT Earth in several iterations here:
- Greubel Forsey GMT Earth in white gold, reviewed in 2012
- Greubel Forsey GMT Earth full hands on review on Feb 2015
- Greubel Forsey GMT Earth Watchscapes for big pictures published on Aug 2018. In this white gold edition, the Earth is fully revealed.
It even sprung off as a new line, featuring the new, sporty GF Sport which was released in December 2018:
- Greubel Forsey GMT Sport full hands on review on Dec 2018. This is a new line based on the GMT Earth, but encased in a new sporty case.
- Greubel Forsey GMT Sport new case with bracelet in 2021
At the moment of writing this, we are not sure if the GMT Sport series, introduced only in 2019 will be discontinued as it shares the same movement as the GMT Earth. We have requested for more information on this from Greubel Forsey, and await their response.
In this latest Final Edition, the off center hour, minute and seconds display remain. The hands are large, and openworked, finished with a SuperLumiNova tip. The small seconds hand is on a sapphire disc at 3 o’clock. On the left is the GMT indicator with its red hand against a hand engraved black gold disc filled with lacquer. And next to the crown its the power reserve indicator – black, engraved gold segment which is filled with lacquer and covered by a silver polished steel hand. And between 7 and 9 o’clock, the Earth ball is revealed. It makes one complete revolution every 24 hours, and looks like it is floating in free space. And as with the earlier editions, the worldtime display for 24 timezones are displayed on a disc.
Greubel Forsey GMT Earth Final Edition
The Earth turns and Greubel Forsey keeps moving. Today, the Atelier unveils the third terrestrial interpretation of its GMT Earth. This unique and now even more modern creation features a new titanium case and is adorned with an even more elegant intense black finish : limited edition of 11 pieces.
The Earth is a global village that man cannot explore in a single glance: the vastness of its spaces and curved geometry present us with an never-ending horizon. At least, until now. With the GMT Earth, Greubel Forsey has created a watch that, for the first time, makes it possible to appreciate the entirety of the world in a single glance.
This technical feat first appeared in 2011. At the time of the first “GMT”, the Earth was not yet fully revealed. Seven years later, the design of the Earth was finally complete: visible from all angles in its new sapphire alcove, it appears as though it is floating in space. On the front as well as the back, the laser-engraved Earth shows world times that are both quick and easy to read.
The first version of the GMT Earth was in white gold. The second, in platinum. Today, this timepiece is available with a new titanium case.
Almost twice as light as steel, it is impervious to temperature variations, non-magnetic, hypoallergenic and eight times stronger than gold or platinum, but requires extremely technical know-how and equipment to be manufactured and finished.
The GMT Earth in titanium will be available in a limited edition of 11 pieces, three times less than the original version. Weighing just 117g, the weight on the strap has been reduced by two-thirds. The case has lost just over a third of its weight. Titanium is used not only for the entire case, but also the bridges, the GMT push-piece, the crown and the folding buckle, the latter two being the components most exposed to shocks and scratches.
To accompany the light and matt tones of titanium, Greubel Forsey opted for a black finish on the dial. It is applied to the spotted bottom plate and to all the frosted bridges, with straight flanks, polished bevelling and countersinks. This finish is also featured on an all-black natural rubber strap, whose inner face is engraved with the cardinal values of the Greubel Forsey Atelier and which are visible on the bezel.
