Yema
Yema is a French watchmaker founded in 1948 in Besançon, producing sport-oriented mechanical watches—dive, chronograph, and pilot models—and owned by French family group Montres Ambre since 2009.
Yema's reputation rests on rugged French tool-watch DNA—the Superman dive watch introduced in 1963 and the Rallygraf chronograph series from the late 1960s both remain in active production today. Under Montres Ambre's ownership since 2009, the brand has developed proprietary calibres assembled in Morteau, France, and maintains active supply relationships with the French military, alongside historical CNES space-agency collaborations. It appeals to buyers who want French tool-watch heritage and in-house movement development outside the usual Swiss-brand set.

What to know
Cases run predominantly 39mm and 41mm with 19–20mm lug widths; the Superman Slim CMM.20 is 9.95mm thick, while current official Superman Steel CMM.10 and Superman Heritage references list 11.30mm case thickness.
Prices span roughly $420 for a meca-quartz Rallygraf chronograph up to $2,790 for the in-house CMM.20 Superman Slim, with select limited editions above $4,000.
CMM-series and limited-edition runs can sell out; Yema lists current availability on yema.com and yema.us for US-based orders.
US buyers can order via yema.us or retailers including Windup Watch Shop and Long Island Watch; Yema's current official storefront states Delivery Duty Paid for U.S. customers, with no hidden duties or taxes at checkout.
Potential comparison sets include Oris Aquis and some Tudor Black Bay dive models, but Yema's main distinction is French tool-watch heritage and in-house CMM-series movements at lower entry prices than many Swiss alternatives.
