Hi all. I have my fathers inscribed SG that was given to him by IBM for 25 years service back in 1992. Unfortunately he never wore watches much and left it in the box all these years. I took to a watchmaker to have a battery put in and the old battery had melted I guess and gummed everything up. They tried to clean it and free up the movement. It was determined that they could not. He left a fresh battery and one day it began to run and keep good time. Now it has quit again and the battery is less than a year old. I am assuming it needs a new movement. If the local person can not do that where should I send it off to? Authorized Concord Service Center? Also do you have any idea how much that should cost or is it something I can do myself if I can find a movement for it? I am willing to put what I need to to save it for obvious reasons, but don't want to muck it up. Thank you.
