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
Jaeger-LeCoultre Duometre 37 mm Skeletonised Quartz sits within Jaeger-LeCoultre's Duometre line, introduced in 1982. It carries the house codes established since 1833 — quartz tpt case, skeletonised dial and in-house manual-winding, hand-finished — 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Jaeger-LeCoultre has spent more than 193 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Reverso, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Antoine LeCoultre established Jaeger-LeCoultre in 1833, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Jaeger-LeCoultre calibre produced today.
