Dad's 1954 Century seems stuck to my wrist! I've been running it against the quartz clock... its running +2 or 3 seconds a day. Not bad! My Dad was a railroader and I remember him crabbing about this thing needing regulating if it ran outside 3 seconds a day. And this wasn't his railroad watch, it was the weekend watch!
Now on Cordovan,ready to start into life with me (creasy that tritium nearly 30 years and looks like new)
