This is one of the common form movements by Bifora, which was used in many ladies’ watches. It uses a pallet lever escapement, a Bishock shock protection system and a regulation system with a long regulation hand. The rest is business as usual, only the tight composition of the gears (a 3 o’clock) is noteable, it allowes a larger mainspring.
