Comments about the data

Remarks
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

Unique design (Fig.3): With an intermediate wheel A between barrel B and minute wheel C the complete train is moved to the periphery. And due to the indirect sweep second D (click Fig.3), there is also no second wheel in the center. Thus neither balance nor barrel is overlapped by any wheel, and the complete height is avalaible for barrel and balance. The result is a rather low profile without reducing sturdiness or accuracy.

Trouble-maker?
This movement is usually only seen in pictures, since the just 11% higher Poljot 2209 made the race, because it was a bit simpler and thus cheaper. Moreover experts believe that it is pretty difficult to assemble, because 5 pivots must be simultaneously fed into the train bridge. All nonsense: The movement is so slim that the wheels can't wobble. Fig.3 demonstrates how they stand pretty upright even without bridge. Actually only the bridge must be put in place, and the pivots find their holes in the jewels alone. And this is no expert oppinion - just my experience as hobbyist, who has occasionally already troubles when feeding two pivots into their holes.
