The movement is functioning well. The case is attractive, showing some wear with surface scratches and scuffs. The dial is in very good condition, although it has some scuffs on the delimitations of the temperature and time dial that are noticeable under strong magnification. There are also some minute blemishes on the chaud inscription.
