A Reverso watch can be turned over. On the Hybris Mechanica Calibre 185 Quadriptyque, that simple movement becomes something almost inconceivable: the watch has four functioning dials distributed across the reversible case and its cradle. Jaeger-LeCoultre unveiled the model in 2021 after more than six years of development. [1][2]
The maison states 11 complications. That is the watchmaker’s term for functions beyond standard time display. Here, astronomical indications are among those accommodated within the rectangular construction. The watch follows three different lunar cycles: the synodic, draconic and anomalistic. According to the manufacturer, the combination can be used to predict events such as eclipses and supermoons. [1]
What makes it special is not only the number. The original Reverso idea from 1931 was a case that could be turned to protect the dial. Quadriptyque uses the same movement to shift between four different mechanical worlds. The technique becomes something the owner actively explores, rather than something hidden beneath the caseback.

Jaeger-LeCoultre described the model as the most complicated Reverso the company had presented to date at launch. This is a historical description of the collection, not a claim that it is the world’s most complicated watch today. [1]
The official press images show a watch from 2021. We have not verified current price, production or availability, and the article therefore presents it as a remarkable piece of horological engineering rather than a current advertisement.
