The movement is operational, though there are some light tarnishes and scuffs on the plates. The hour hand does not return to the 12 o’clock position when pressed and requires repair or adjustment. The dial has minor scratches and slight chipping around the winding aperture. There is rubbing and wear on the gilding of the bezels, and the pendant is slightly loose.
