I own a Seamaster Automatic Racing 3602 for 8 years (11/2007). One the 6th year the chronograph has failed once (that took 500 euros for the repair...) After 1 year and half the crown just unwinded. As I tried to screw it back, I broke it I went back to the official Omega offices, and guess what.. they asked 500 euros for the repair. Seeing a wristwatch of 3700 euros to need extra 1000 euros within 8 years, it really makes me wonder. Definitely, I am not going to have it repaired in the official Omega, since I am pretty unsure about the quality of their work. Now, my question dear fellow-omega-owners is if you know where I could find the CROWN only. Thanks in advance for your time.
