Platinum Status for Greubel Forsey’s Signature 1

Platinum Status for Greubel Forsey’s Signature 1

March 15, 2017

Following the first two versions, each with an 18-karat rose gold case or white gold case, the Signature 1 by Greubel Forsey is now also available in a platinum version with an anthracite black-colored gold dial.

Long-time team member at Greubel Forsey, Didier Cretin inaugurated the Signature series in 2016, for which one watchmaker, chosen for their talent and original approach to watchmaking, creates their own timepiece within Greubel Forsey’s universe and cosigns it with Robert Greubel and Stephen Forsey.

The Signature 1’s large balance wheel has a 12.6mm diameter.

This project, which aims to showcase watchmaking skills, is reminiscent of the Naissance d’une Montre project, which archives techniques that are starting to disappear. The Signature project intends to further extend this desire to convey our particular vision of fine watchmaking to future generations: that of timepieces primarily designed by visionary men and women, served by excellent technology and expertise, which must be preserved.

Didier Cretin designed a hand-wound watch with three hands, without a tourbillon function, which instead features an exclusively designed Greubel Forsey balance wheel.

In this new platinum version, the off-centered placement of its dial in anthracite black-colored gold forms a contrasting counterpoint to the mechanical contents. The dial, minimal and flat, invites the eye to explore the interwoven lines of the watch’s metallic, architectural depths. This is a complex watch creation that is characterized by great restraint. The hour-ring and minute-circle appear in white. An individual number is engraved by hand on the back of the timepiece.

A total of 11 platinum Signature 1 pieces will be produced.
