I recently won an eBay auction for a vintage Seamaster, 166.090, with the 1002 movement. It is losing time so obviously is in need of service. I took it to the local Authorized Dealer who quoted me $700-$800 for a factory service. I was not willing to pay that and I understand that the watch would receive a complete overhaul. My goal is an accurate watch. I presume that a cleaning and lubrication will make this happen. I have picked up several automatic and manual wind watches that could use a service also. Having said all that, what is a reasonable cost for the service I described? Would an Omega be more costly that a Gruen or Waltham? Finally, how does one find a watchmaker capable of doing the service?
