Authentication note
Why this detail matters.
Crown signing is precise on genuine watches: the emblem's geometry, relief depth, and proportion to the case are all catalogued and checkable. Replacement and aftermarket crowns are common on serviced vintage pieces, which affects originality rather than genuineness. A crown that sits crooked, threads roughly, or carries the wrong emblem for the era is an early warning worth following into the case.
