The movement is in working condition. The chiselled ornaments in blue enamel are nice and intact. The dial shows slight oxidation at 12 o’clock. The chapter ring has minor imperfections at 10 o’clock. The seconds hand has oxidation in the center. The case shows signs of wear. The pendant loop exhibits surface wear. Otherwise, the watch is beautiful and in very good overall condition considering its age.
