Does anyone know if the 40mm "Quaranta"-series have snap-on, driven or screw-down case backs?
I know the 42mm and 44mm "Luminor 1950"-s have screw-down casebacks, but they also house the P.9010 while the Quarantas house the P.900.
EDIT: According to this site, they're screw-down, but I'm not sure where the author got the information from:
