Not the snappiest brand name - Peercee was a brand of Stauffer, Son & Co.
The movement is marked 7030. It is very like some FHF movements such as the 7018 bidfun-db Archive: Watch Movements: FHF 7018
So I guess its a FHF 7030 - but can't find such a calibre listed anywhere. Anyway, the other interesting thing is the horseshoe logo on the movement. it actually has S S & Co written inside it. Running, keeping time, but with a broken or slipping mainspring.
