Memoris nominated for the Grand Prix d’Horlogerie of Geneva

Memoris: a genuine horological invention

Memoris is not just the latest reinterpretation of a chronograph – an exercise that has been done to death. Memoris is the first ‘chronograph watch’ in history: a timepiece that has been developed entirely with the ‘chronograph’ complication uppermost in mind, especially designed for the piece and in full view on the dial. In an unprecedented move, the time display thereby becomes secondary, offset here to six o’clock.

Memoris: the quintessence of technology

The Memoris LM54 caliber, is wholly exclusive to the piece. With a rhythm of 28,800 vibrations per hour (4Hz), it boasts 302 components – and a 48-hour power reserve. Over sixty parts have been designed and manufactured to allow the chronograph to be presented atop a dedicated movement plate, separating it from the automatic movement beneath.

The chronograph: king of complications

Watchmakers often consider the chronograph to be the finest of watch complications. Comprising a total of over 300 parts, Memoris is perhaps the most spectacular chronograph made to date: its entire function – 147 parts – is fully visible on the dial side. The three functions of the column wheel, operated by its monopusher, can be seen. The assembly includes two separate hammers, another rare feature. And the swivel of the yoke is aligned along the same axis as the second wheel, further ensuring quality.

Energie Plus: the future of automatic winding

For the past few years, Louis Moinet has been developing and perfecting a completely new winding system, named Energie Plus – and Memoris benefits from the most advanced version. The process relies on a pawl system, featuring a spring with a ‘crab claw’ design, along with a ceramic ball bearing mounted on the dual-material rotor.

The advantage of “Energie Plus” is that it allows the piece to be wound up in both directions, with a minimum of excess travel. This optimizes each movement of the rotor, recovering its energy, and winding the movement more effectively. This particular invention has already earned the Mecanograph a prize in the Chronometry Competition.

Memoris: the crowning glory of Louis Moinet’s first decade

In just ten years, between 2004 and 2014, Ateliers Louis Moinet has created its identity and fine-tuned its positioning, developing coherent, innovative and exclusive haute horlogerie collections. First unveiled in March 2015, Memoris is the epitome of the brand’s first decade – highly creative, and proudly, fully independent from the very beginning.

Memoris: a vibrant tribute to one man’s genius

Mr Louis Moinet invented the chronograph in 1816. Memoris pays tribute to the man who laid the foundations for modern watchmaking in his Treatise on the subject (1848). As the first chronograph-watch in history, Memoris is opening up a new path, just as Mr Moinet did two centuries earlier – making a landmark contribution to restoring Mr Louis Moinet’s name to the pantheon of watchmakers.
