Crowns are winding-stem and case specific, and sometimes even screw down in case of waterproof watches.
This review is about "the normal crowns".
To select the right crown for your watch you need to know:
-
the stem size/ crown tap
-
the crown opening or case tube diameter
-
the diameter of the crown that you want to replace.
See here our collection watch crowns.
Most important is the stem size, then second is the opening or case tube width. Please don't hestitate to ask for advise!
