Historical significance
Greubel Forsey Balancier 43 mm Slate Carbon sits within Greubel Forsey's Balancier line, introduced in 2004. It carries the house codes established since 2004 — carbon tpt case, slate grey 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 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.
