If you’re interested in Citizen’s fine 8110a flyback chronograph there’s a very informative thread on the Watchuseek forum showing some excellent work by ’31jewels’, who is a master watch repairer. He shows in detail the restoration and servicing work he’s done both on his own and a customer’s watches, and the thread is now complete after starting back in mid-April. A highly recopmmended read!:  http://forums.watchuseek.com/f21/citizen-bull-head-8110a-restoration-service-31-jewels-677877.html
