Condition: Case condition: the center of the top case has been polished at some point, possibly to remove an engraving and compresses when gently pushed in. The center of the case back also compresses when gently pushed in - suggesting an engraving was also removed from the case back. The case does maintain a decent snap. Exceptional dial by my estimation. I can see no chips or hairlines under 10x. Please enlarge the dial picture to make your own determination. The movement appears well preserved. It sets, runs and the split second chronograph function is currently operating correctly. However, the service history is unknown and a fresh service will be required to guarantee accuracy, functionality and insure longevity. Sold with no further mechanical warranty.
