Memoris

The chronograph turned inside out: no longer an added complication, but the very heart of the watch

Model History

Presented in 2016, to mark the bicentenary of the 1816 compteur de tierces, the Memoris line was born from a reversal of perspective that founder Jean-Marie Schaller has repeatedly described in these terms: rather than adding a chronograph function to a watch already designed around time-telling, the Louis Moinet team designed the entire watch starting from the chronograph mechanism, relegating the time display to a smaller dial, shifted toward the bottom of the main dial.

The result is a curved 46 mm case that leaves the mechanics widely exposed: the column wheel controlling the start, stop and reset functions is prominently placed in the upper part of the dial, while a single pusher (mono-pusher), positioned in line with the crown, echoes the control layout already present in the historical 1816 instrument — a direct homage made explicit by the maison itself.

Over the years the line has been enriched with numerous variants: from red gold and white gold editions to the more recent titanium Superlight versions, designed to cut the watch's overall weight, up to executions with hand-decorated dials such as the Red Eclipse, shortlisted as a finalist at the Grand Prix d'Horlogerie de Genève in 2016. All share the same LM54 base caliber, automatic, developed specifically for the line.

Fun Fact

The single pusher of the Memoris, positioned next to the crown, is not merely an aesthetic choice: it deliberately echoes the control layout of the original 1816 compteur de tierces, the instrument from which the entire maison draws its inspiration, proof of how the line was conceived as a genuine dialogue with history rather than simply as a wrist chronograph.
