On the corner of a tablecloth in a small restaurant in the Vallée de Joux, a new concept for the Reverso takes shape. What if the iconic watch were to offer two faces? The dream takes shape with the Jaeger-LeCoultre Calibre 854, indicating the local time on the front, and the traveller’s reference time on the back. Three years later, the ladies Reverso also acquires two faces: a day face and a night face. The Reverso Duetto plays on times, on appearance and on personality.
