Traditionnelle tourbillon retrograde date openface

A distinctly contemporary aesthetic underscores the technicity of this Traditionnelle tourbillon retrograde date openface. The openworked sapphire dial, which includes a guilloché segment, allows a clear view of Calibre 2162 R31, in particular the plate for the retrograde mechanism which is highlighted by a slate-grey surface treatment. Beating at 18,000 vibrations/hour and a slim 6.25mm high, this in-house movement provides 72 hours of power reserve and is wound by a gold peripheral weight. Its combination of a retrograde date with a tourbillon is relatively rare. All the attributes of the Traditionnelle collection are respected, such as the round case in rose gold, which measures 41mm in diameter and 11.07mm high, the stepped lugs, the fluted caseback, the railroad minute track, the bi-faceted Dauphine hands and the gold baton hour-markers. Particular care has been given to finishing, for example the cone-shaped transversal bar of the tourbillon carriage has been hand-polished to a mirror-like gleam.
