Greubel ForseyThe Greubel Forsey Signature 1 is a manual-winding wristwatch characterized as the brand's first time-only model encased in stainless steel. This particular example is described as a piece unique, featuring a black gold dial and a frosted black mainplate.
The movement includes an oversized balance wheel, a floating petite seconds hand, and a winding bridge with an integrated click spring. Development of the caliber was led by Didier J.G. Cretin over a period of approximately six years. The Signature 1 project, which limits total production to 66 examples across all material configurations, allows for the realization of designs by individual horologists within the workshop.
The object is presented as an exclusive steel iteration within the broader Signature series.

The source describes the overall configuration as a unique piece, distinct within the larger production series of the model.
