Today I'm letting may father's US government issue GG-W-113 stretch it's legs. It has a genuine Hamilton 685 manual wind with hacking. I got this for him last year as a father's day gift. The date on the back of the case in June 1969, the year he was there, and exactly 50 years since he was there plus the month Father's day falls on. I can be thoughtful... No matter what my wife claims! It had random issues that I thought were minor, but then it flat quit on him. It has been on my bench since before Christmas waiting on me to troubleshoot it. Yesterday, I finally had some time to do into it. Turns out the lower balance jewel Chaton had moved and just needed to be pressed back some. I had to guess as to how much to move it. Unfortunately I don't own a jewel press, very nerve wracking trying to push on the Chaton and not over do it. But it seems much better now, no stalling or anything. It's keeping excellent time. I gave the Crystal a better polish too. My first attempt was kinda half assed. So, I'll hang on to it and let it run down and sit for a week or so and wind it to see if it takes off. Fingers crossed.
