Picked up a couple today in Amsterdam. The first one Is a Sicura Chrono Graphe, with inner rotating bezel

I think it is missing the outer bezel - where would I find one of those??? Normally I run from incomplete watches, but the condition was good for the rest of the watch including the original bracelet. Anyone have any websites for Sicura history/brochures?
I also bought this. Surely one for @Nigelp

Nothing to do with the motors though! 14k case engraved for 1960, I'm yet to open it up.
All help on the Sicura welcome
