2009 - MBP 1000 watch movement and Montres Ambre acquisition

Yema designed a new proprietary watch movement: the MBP 1000. Equipped with a bidirectional oscillating mass mounted on ball bearings, they allowed a fast reassembly and a power reserve of 40 hours. This resulted in a gain of efficiency but also precision, provided by a regulator whose balance beats at a frequency of 28,800 alternations per hour. Stacking a total of 31 rubies including 2 located at the ends of the axis of the barrel, this technical design effectively reduced the friction generally observed at this element following the mechanical movements.

2017 - Proxima Mission

In 2017, Yema partnered with CNES (the National Centre for Space Studies) to create a new model of watch, the Yema Spacegraf. This model was to honor of the Proxima mission, which sent the 10th French astronaut to space.
