The movement is running. The minute hand is setting smoothly, and the hours seem to be jumping well. The dial’s engine turning remains well defined, with some scuffing and light scratches. The sector for seconds features a double ended seconds hand so that as the tip of one side disappears to the right, the other side appears to the left. The case shows some rubbing and a slight loss of definition in the engine turned decoration at the edge of the case back and bezel. The cover and cuvette close securely.
