both etched crowns are almost the same size...or same size.
I dont have a gen rollie, but maybe gen owners can clarify this mistery.
seeing two cases compared one gainst each other means nothing to me.
all in all both are made of steel, both have the same diameter, both have a very similar bezel.
Both have the same finish..
What counts is the milimetric construction. Otherwise a gen crystal wont fit, case will need to be modded to fit gen tube and so...
