1895: Grand complications
From the mid 1890s onwards, the LeCoultre & Cie Manufacture started making calibres for watches with grand complications. This noble title is reserved for watches with at least three classic complications such as minute repeaters, chronograph or perpetual calendar.
Since then, Jaeger-LeCoultre has carried on the great tradition of ultra-complicated watches which earned the Joux Valley its nickname of “the Rome of grand complications”.
