Designer
Gérald Genta
Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.
Historical significance
Greubel Forsey Balancier 37 mm Mother-of-pearl Carbon sits within Greubel Forsey's Balancier line, introduced in 2004. It carries the house codes established since 2004 — carbon tpt case, mother-of-pearl dial and in-house automatic with 22k gold rotor — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history
Greubel Forsey has spent more than 22 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Double Balancier, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Robert Greubel & Stephen Forsey established Greubel Forsey in 2004, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Greubel Forsey calibre produced today.
