A magnificent demonstration of expertise harnessed for the pursuit of fine craftsmanship. That’s how can be explained Greubel Forsey’s limited edition of its GMT Platinum Black Dial. In this new timepiece, we can recognize the “Greubel Forsey signature“, the utmost care is taken with the decoration of the components, down to the smallest details. The hand finishes take in the entire range of traditional techniques, from frosting to hand-bevelling, as well as the subtleties of hand-polishing, lapping, and straight graining with flat black polished finishes.
The domed crystal, the case-back and lateral window are made from sapphire crystal. The hand- stitched black alligator strap has a platinum folding clasp.
The GMT calibre is powered by two barrels providing a 72-h power reserve with a frequency of 21,600 vibrations/hour. The calibre comprises 443 components. It features a 24-second tourbillon with 25° inclination, comprising 87 components for a total weight of 0.36 g.
Besides its chronometric properties and reliability, this regulator system was adopted for its small size, which meant that a calibre diameter of 36.40 mm (16 ½ lines) could be kept. This makes for a new medium-sized case, 43.5 mm wide with a total height of 16.14 mm.
Made from 950 platinum, it has a slightly lighter hue than the previous white gold version, but this piece will cost you around $640,000.
