Yema MBP1000
High confidenceThe brand's own caliber, and its presence separates modern production from everything earlier: period Yema used bought-in Swiss and French calibers throughout. One qualification on the in-house claim, which Yema itself makes plainly rather than obscuring: the movement is assembled at Morteau from a mix of domestic and foreign components. That is manufacture in the ordinary modern sense and not a criticism — but 'in-house' and 'made entirely in France' are different claims and only the first is supported.
