Ever since the creation of Greubel Forsey in 2004, we have made it our goal to create timepieces that are a source of lasting satisfaction and intense emotion for our collectors. We engage our full responsibility in working to guarantee the exclusivity and value of each timepiece. Hence the unchanged rhythm of our production over the last decade: in spite of constantly growing demand, we deliberately limit our output to a hundred pieces a year, for the priority given to supreme craftsmanship inevitably means rarity. Greubel Forsey thus has a very special relation to the watchmaking heritage, which the company strives to maintain. Our approach to fine watchmaking is not unlike the way the art market approaches artworks, moving carefully between unique editions and editions of one. Each of our timepieces is scrupulously inventoried by hand in our "Grand Livre", ensuring traceability. Greubel Forsey has decided to offer Christie's clients an expert appraisal service in order to guarantee full satisfaction on the timepieces they acquire at auction. Thanks to a certificate offering full servicing, collectors can take their timepiece to any authorised Greubel Forsey retailer for a complete check-up. This Grand Service certificate is valid for six months from the date of acquisition at Christie's. Greubel Forsey will cover the cost of the servicing, while transport will be at the collector's expense. Combining Christie's expertise and Greubel Forsey technical support, this innovative partnership is yet another illustration of our determination to ensure quality over the long term, and thus to maintain the heritage value of our timepieces. In creating this personalised service, we wanted to pay tribute and convey our deep respect to the connoisseurs of fine watches who place their trust in our work.

The GMT model is another ground-breaking and spectacular timepiece by Greubel Forsey. The GMT features a spectacular three-dimensional temporal representation of a rotating terrestrial globe, offering the wearer a truly unique view of time all over the world. This technical marvel provides a whole new way of perceiving the different time zones. Nestled in a prominent position at 8 o'clock, the 3D titanium sphere is ingeniously secured at just one end of its rotational axis, the South Pole, allowing optimal views. While the globe makes one complete rotation every 24 hours anticlockwise, the Earth's natural rotational direction, the position of the continents can be cross-referenced with the 24-hour, day & night indicator on the equatorial chapter ring.

The movement was crafted with 436 components, 87 of which are used in the tourbillon cage, only weighing an impressive 0.36 grams. The Tourbillon 24 Secondes incliné is Greubel Forsey's third fundamental invention. The T24Si is a single inclined exquisitely finished tourbillon cage that undergoes rapidly changing positions with a high angular velocity, giving the impression that the whole complication is in orbit while offering the wearer a unique display of the tourbillon. Also, two co-axial mainspring barrels connected in series provide a power reserve of 72 hours. Furthermore, the plates and bridges are beautifully hand-finished, frosted, and beveled.

This horological masterpiece is a solid validation of the underlying fundamental inventions of Greubel Forsey, with an objective to reinforce the link between mechanism and indication, as well as the relentless pursuit to improve timekeeping precision.
