I am not certain whether I have ever seen the name "Dubois-Depraz" on the dial of a caliber 12 chronograph. If so, then these would be exceedingly rare. Maybe Dubois-Depraz received some prototypes from the joint venture, and had some dials made for them. I would expect that they were never sold commerically under this name.
Have you ever seen a caliber 12 with the Dubois-Depraz name on the dial? If so, we would like to learn more about this.
