The movement is in working condition. All diamonds are nice and intact. The dial shows minor wear due to ageing, with a tiny scuff mark visible to the naked eye between 12 and 1 o’clock. The case exhibits minor signs of surface wear throughout. Overall, the watch is in very good condition considering its age.
