Diameter without crown 48 mm and height with glass 12 mm.
Movement number 36027 - roughly from 1929?
Case number 506160 IMPORTÉ DE SUISSE.
Visible movement diameter 38 mm.
What sources do you have regarding the caliber?
I consider Rössler's book only as a suggestion.
In purely mathematical terms, that would only be 17'''. However, the 18.28.3A, for example, is specified in the data sheet with 39.6 mm - measured behind the retaining ring - and...
