The Bidlingmaier 812 watch movement is a manual wind movement with a sub-second function. It was produced by FHF, specifically at their factory named Fabrique Robert in Fontainemelon. The Bidlingmaier 812, along with other Gruen calibers such as 100, 101, 620 through 623, 626, and 627, are believed to be based on the FHF Robert 8.75''' calibre downsized to 8'''. However, due to limited available information, reliable details cannot be provided. This movement was used in watches from 1917 onwards.
