Abstract
A crown lock structure for a timepiece has a crown having an inner surface provided with a threaded section and a connecting assembly for removably connecting the crown to a case of the timepiece. The connecting assembly comprises a tubular member for integral connection to the timepiece case and a tubular insert removably connected to the tubular member. The tubular member has a first tubular portion for insertion into a through-hole of the timepiece case and a second tubular portion integral with the first tubular portion and removably connected to the tubular insert so as to prevent relative rotation between the tubular member and the tubular insert. The tubular insert has a threaded section for threaded engagement with the threaded section of the crown to removably connect the crown to the timepiece case.
