I am sure the chrono would be fixed in a service. When they service the watch they take everything apart, clean each part separately, and replace any broken or worn parts. Everything gets put back together in working order. I am not a watchmaker, but if nothing is broken fixing the chrono will not add to the service. Small parts are usually not too expensive. I just had my Speedmaster serviced by an independent watchmaker in Portland, OR that was recommended here (Kelly Hunter at Art of the Watch). The chrono could not be stopped once started. It cost me about $25 to ship it registered and insured mail from Northern California. The base service price was $550, new genuine Omega crystal was $85, new Omega crown $50 and the part to fix the chrono was $70, and he charged $55 to ship it back. The watch looks great and works beautifully.
