Founder Hans Wilsdorf set up workshops around the world from the start, so each watch could be serviced to the same standard wherever its owner lives. A full service begins with the bracelet separated from the case and the movement lifted out, dial and hands still attached. The movement is dismantled entirely, each component examined, then cleaned in an ultrasonic bath and reassembled piece by piece. Case and bracelet are polished or satin-finished by hand to match their original finish, and the seals are replaced. Testing follows: a precision run of at least 24 hours, then a pressure check in water, then a final control of rate, function and appearance. Parts and labor are assured for at least 35 years after a model leaves the catalogue. Each serviced watch returns with a two-year international guarantee, ready to be handed down and live several lives; KirkJewelers.com.
