The movement is currently in working condition. The mother-of-pearl dial is in good shape and intact, although the indexes and hands show some signs of wear and oxidation. The case exhibits light wear that is consistent with the watch’s age. The case back has very tight hinges and also shows light wear. Overall, the watch is in very good condition for its age.
