Designer
Jörg Hysek
Jörg Hysek left Rolex and Seiko's European studios to build a design practice in Geneva, giving houses such as Vacheron Constantin, Breguet, Seiko and TAG Heuer their sculptural, architecture-led cases before founding his own brand, HD3.
Historical significance
Greubel Forsey GMT 38 mm Meteorite Grade sits within Greubel Forsey's GMT line, introduced in 2013. It carries the house codes established since 2004 — grade 5 titanium case, meteorite dial and in-house automatic micro-rotor — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

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.
