When the inventor of the chronograph creates a contemporary interpretation of its 1816 claim to fame, you know it’s not going to be just another timepiece. And truly, the Louis Moinet Memoris is something else. Designed as a tribute to the original compteur de tierces pocket watch which dates back two centuries (and also to commemorate Louis Moinet’s 10th anniversary), the Memoris places emphasis on its chronograph function above all else.
So much so that all of the chronograph’s 147 components are placed on top of the movement’s mainplate, while its timekeeping elements are relegated to the bottom — a configuration that makes standard timekeeping seem like an additional complication instead of a primary function.
The result is a visually arresting dial which magnificently showcases the entire chronograph mechanism, unobstructed by the other 155 components that make up the horologe’s LM 54 calibre. Setting the chronograph in motion is a monopusher decorated with a Clous de Paris pattern, located at the two o’clock position.
Originally invented for astronomical use, the historical chronograph could measure up to 1/60th of a second. It also ran at an impressive frequency for watches of that period, at 216,000 vibrations an hour. While the Memoris operates at a lower frequency of 28,800 vibrations per hour, it is no less of a masterpiece. The watch is notably fitted with the brand’s high performance Energie Plus system, which improves winding efficiency by about 30 percent. Comprising a pawl system that features a spring with a “crab claw” design and a ceramic ball bearing mounted on the rotor, the award-winning mechanism captures the movement of the oscillating mass in both directions, minimising excess travel and hence transmitting more energy to the barrel spring compared to a conventional self-winding system.
The 46-mm ticker offers a power reserve of about 46 hours and is available in rose or white gold, each limited to 60 pieces.
