A COA service (a.k.a. COR or Overhaul) is our most complete service. Most manufacturers recommend that you have a COA completed every 3 to 5 years. Unlike the “service” offered by some other watch care facilities, where they may simply “clean your watch case and add a little oil”, our expert watchmakers follow manufacturers service guidelines to provide a fully intensive service.

 

A COA service consists of the following:

  • Disassembly of the watch case, bracelet, and movement with a careful assessment of all parts for wear and damage.

  • Movement parts are thoroughly cleaned in a multi-stage ultrasonic cleaning machine. Worn or damaged parts are replaced.

  • The movement is reassembled using several types of high quality horological lubricant. The correct lubrication of the movement is essential to ensuring your watch continues to serve you for years to come.

  • Using an electronic timing machine the movement is calibrated and adjusted for correct time keeping. The movement is tested in multiple orientations in order to verify the correct Amplitude and Beat Rate and to reduce Beat Error.

  • The case and bracelet are polished, refinished and ultrasonically cleaned to remove scratches and blemishes.

  • The watch is reassembled with new gaskets and seals, and if applicable, a water-pressure test is performed.

  • All watches are then monitored during a 48 to 72 hour time test before being returned to the client.
