History

Henry Louis Belmont, the year 1931 graduate of the National Watchmaking School of Besançon founded his watching company under the name Yema in 1948. In few decades, by the 1960s, Yema became the largest French watch manufacturer, producing over 500,000 watched annually.

In 1963, the company launched Yema Superman for divers. Many variations were produced by the company for this model of watch.

In 1966, the first Yema Yachtingraf was launched, a watch especially designed for sailors. At the same time, the first Yema RallyGraf was launched. One Yema RallyGraf was even worn by Formula One champion Mario Andretti.
At the start of 1970, Yema became an official supplier of the French Sailing Federation and equipped the French National Sailing Team in the 1972 Olympic Games.

1982 - First French Watch in Space

On 24 June 1982, French astronaut, Jean-Loup Chrétien, flew from the Baikonour base for a 10-day trip into space, wearing a Yema Spationaute I, making it the first French watch in space.

1986 - North Pole Mission

In May 1986, Yema joined forces with French physician and explorer Jean-Louis Etienne to cross the North Pole.

2009 - MBP 1000 watch movement

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 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.
