Interpreting Soviet/Russian movement and case codes



Russian movement/case codes come in a AB CDE / FGH I JKH format.

AB = movement diametre in mm

CD, CDE = Soviet movement specification

see table at bottom of page

FGH = case variation

I = case material

Examples below from Vostok

0 : stainless steel and other metals without plating

1 : chrome plated

2 : gold plated

3 : gilded (at least 5 microns)

4 : colour coated

5 : synthetic, polymer, rubber

9 : glass, crystal, ceramics, marble

JKH = Hand set

As a consequence of this system there's a 24 16 Slava, 24 16 Vostok & a 24 16 Poljot movement that bear no similarity to each other, except that they match the 24 16 specification (automatic, central second hand, shock protected & date plus all are 24 mm in diametre).
