Bicentenary of the Chronograph Limited Edition of 20 Pieces
The "Memoris 200th Anniversary" can be summed up in three points: - A new hour dial made in enamel for the first time in history of the piece - A new mainplate, painted and decorated with star constellations - A new translucent flange and counter bridge.
The starry back consists of a brass plate coated in a translucent blue. The stars have been created using an entirely new fixed graver process. Devised by one of Louis Moinet's craftsmen, this involves attaching a specially-made lathe to a traditional rose engine (also known as a guillocheuse). The idea is to combine the power of the rose engine with the precision of a handheld graver. The result differs from that produced by milling or stamping: while it resembles the effect traditionally associated with a guillocheuse inasmuch as material is removed, here this is focused on a tiny area with varying levels of depth two characteristics that traditional engine turning seeks to avoid at all costs.
Individual stars are all fashioned to feature different angles and depths, so that each and every one captures as much light as possible. Several fixed graver sessions are required per star. The process used is unprecedented in watchmaking and the outstanding result gives the novel impression that certain stars really are shining.
