THE IN-HOUSE MOVEMENTS

For more than 30 years, the precious mechanical timepieces of Maurice Lacroix have been produced with utmost precision and perfection by experienced watchmakers in own watchmaking facilities. Where the fine finishing work and the assembly of sometimes microscopically small movement parts are concerned, the experienced hand of the watchmaker and profound knowledge passed down from one watchmaker generation to the next are still very much in demand.

ML 106-2 Masterpiece Le Chronographe

 

The first of their kind in chronograph technology.

The ML 106 movements take that rarest of mechanical watchmaking achievements – the 60 minute counter – and add to it two unique patents. Now with an innovative new release lever and a totally redesigned cinematic chain wheel, these movements have improved on a chronograph design unchanged in the industry since the 1800s. More precision, more reliability, no more than you’d expect from Maurice Lacroix.

ML 150 Masterpiece Calendrier Rétrograde

 

As if precision, hand-crafted time measurement wasn’t complex enough, the ML 150 movement interweaves it with a power indication and retrograde (semicircular) date display. It is this spirit of constant improvement that epitomises the Masterpiece range. And the reason why the ML 150 also features black gold coated bridges and no less than 35 jewelled bearings.

A day is one revolution of the Earth. The time it takes, is what the average watch is built to measure. The ML 152, however, is no average movement. Balanced with retrograde (semi-circular) date and power reserve displays, it also measures time by the movement of the moon – charting the lunar cycle on a celestial display. A humbling reminder that time does not just revolve around us.
