Notes
Raketa combined settings for escape wheel
indirectly driven minute allows a very big balance
striking: The cannon pinion is rather thick (minute-hand hole 1.05mm). The reason is that this pinion runs idle on a fixed tube, which carries a jewel bearing for the second-hand arbor in its top.
unusual: conventional winding gear on dial side
