The Baumgartner 666 watch movement is a manual wind movement with sub-second functionality. The movement incorporates a pin-lever escapement and features a ratchet on the dial side, as well as a crown mechanism with a rocker bar. It bears a close resemblance to the balance screws found in high-end movements. Notably, there is similarity with the 1343 movement, although specific differences between the two are not currently known. The Baumgartner 666 movement is commonly associated with watches produced around the 1950s.
