60's Hamilton Dateline A-577, cal. 694a(eta 2472). Cleaned/serviced.

I've held off on this one for over a year because I thought rhe tension fit bezel was missing. Then I just saw another one and realized that's just the funky design, haha. the two biggest issues getting into this was the rotor grinding and the very poor trace. Once I opened it up, you can see the loose screw for the rotor. Nearly all the screws were loose as well. after cleaning we have over 325 ° of amplitude and a flat trace without even touching the regulator.
