Historical significance

Jaeger-LeCoultre Reverso 39 mm Blue 18k sits within Jaeger-LeCoultre's Reverso line, introduced in 1971. It carries the house codes established since 1833 — 18k rose gold case, blue "grande tapisserie" 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
  • The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

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.
