Designer
René-Alfred Chauvot
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Jaeger-LeCoultre Reverso 44 mm Skeletonised Sapphire sits within Jaeger-LeCoultre's Reverso line, introduced in 1986. It carries the house codes established since 1833 — sapphire crystal case case, skeletonised 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
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

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.
