Only manufaturing was transfered to another factory in 1975. Unique design (Fig.3, 4): With an intermediate wheel A between central minute pinion B and a separate minute wheel C the complete train is moved to the periphery (Fig.4). And due to the indirect sweep second, 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. Wheel C is not actually a minute wheel; the gear ratio between its pinion (8 teeth) and the central minute pinion B (12 teeth) was optimized, and wheel C turns once in 40 minutes. Example, year: signature; shock device 1-2) ca. 1965: 1368107, Cyrillic: 1st Moscow Watch Factory (Poljot), 23 jewels; Poljot 3-4) ca. 1977: Luch, 2209, (Cyrillic: 23 jewels); Poljot (Luch 2209) Not for Sale!
