... as you can see on this picture I shot two years ago:
Other customer brands include(d) R. Dubius, Bovet, JLC, Lang&Heyne, Breguet, and Omega.
Regarding Omega, I have been informed that the Swatch Group now has own facilities to produce enamel dials, apparently in a quicker, more industrialized manner, as the relatively high edition of recent enamel Omegas suggests.
