Yema
For those who want real French watchmaking history at an accessible price.

Yema was founded in 1948 in Besançon, France, by Henry-Louis Belmont, and by the 1960s and 70s had grown into France's largest watch manufacturer, producing over two million watches a year at its peak. Today it's run by the Bôle family from its Morteau manufacture, building genuine in-house calibers alongside reissues of its historic dive, motorsport, and space-flight references.
France's most historically significant independent watchmaker — the Superman dive watch (1967), the Rallygraf motorsport chronograph, and a real in-house manufacture in Morteau — spanning accessible quartz references to genuine mechanical calibers.

The brand
About Yema
Yema was founded in 1948 in Besançon, France, by Henry-Louis Belmont, a graduate of the National Watchmaking School of Besançon. By the 1960s and 70s, Yema had grown into France's largest watch manufacturer, producing over two million watches a year at its peak.
Superman, Rallygraf, and Spationaute
In 1967, Yema patented one of the first locking dive-watch bezels for the Superman, which became the first French production dive watch rated to 300m. The same year saw the launch of the Rallygraf motorsport chronograph, which Mario Andretti wore during his win at the 1969 Indianapolis 500. In 1982, French astronaut Jean-Loup Chrétien wore a Yema Spationaute, developed with the French space agency CNES, into orbit.
The Morteau Manufacture and In-House Movements
The 1980s quartz crisis pushed Yema through a difficult ownership chain — acquired by industrial group Matra Horlogerie in 1982, then by Seiko in 1986 — before a French buyer took the brand back in 2004. Since 2009, Yema has been part of the Bôle family's Morteau-based watchmaking business, which has since built genuine in-house calibers: the CMM.10 automatic and CMM.20 micro-rotor, both designed in-house with mainplates and bridges built at Yema's own Morteau workshops and regulating organs sourced from Switzerland.
Where Yema Sits Today
Yema today spans accessible quartz and Meca-Quartz references built around its historic Rallygraf and Navygraf designs, up to CMM manufacture-movement pieces that cost several times more. It's aimed at buyers who want genuine French watchmaking history — dive, motorsport, and space heritage all attached to real vintage references — without paying Swiss-manufacture prices.
What sets Yema apart
Yema designs and partly builds its CMM.10 automatic and CMM.20 micro-rotor calibers at its own Morteau manufacture, unusual for a brand at this price point.
The 1967 Superman patented one of the first locking dive bezels and became the first French production dive watch rated to 300m.
Developed with the CNES space agency, the Spationaute was flown in orbit in 1982 by French astronaut Jean-Loup Chrétien.
