6497-1

Not a Panerai calibre at all, but the ETA/Unitas 6497-1 fitted essentially as delivered, before the company began reworking the ébauche under its own OP designations. The 6497 began life as a Lépine pocket-watch movement, and its 16½-ligne diameter is precisely what made Panerai's oversized cases workable. It winds by hand; there is no rotor.
