I purchased a vintage Cimier chronograph recently. The seller advertised it with all the functions working, but they did not know its service history. When it arrived, the chronograph function works, and both the second hand and the minute hand reset to zero. Unfortunately, the hand on the chronograph minute dial, after resetting to zero, continues to run. Is this something that a simple service could fix? Also, any feedback on the watch itself or how well I did? I paid $310.
