In a watch shop in Paris, I could fall on one of them, the Rodania Royal Canadian Air Force Chronograph.

To be compared with the almost similar Breitling " RCAF ". Similar size and movement and dial. The movement is the Valjoux 236, with hacking second.
I only have the Breitling. For the moment, as if a good opportunity comes around, I will fall on the two others...
Best,
Nicolas
