The engine turning on the dial plate exhibits a slight linear kink towards the bottom and a small hole near the border on the lower right side. There is a light scratch extending from the dial screw at the lower right side. The white enamel chapter ring displays three hairline cracks and some wear and repair to the inner metal ring. The case is in polished condition and bears a French control mark for Paris ‘petite recense’ dating from 1819-1838. The movement is functioning, but the repeating function is somewhat sluggish.
