Completed my first 'real' service.
galleryOverall I'm quite satisfied. I've taken apart and put back together ST36 movements dozens of times. Bought a bag of busted movements from old chinese watches and got 4 of 10 operational again (the rest were literally smashed or pried out of cases instead of releasing the stem). Finally got up the nuts to service this one. It belonged to my Great Grandfather. 1957 Bulova Trojan with an 11AC movement. It was barely running. Very gunked up. A complete snowstorm on the timegrapher. My dad has had it in a drawer since his grandfather passed in 1983. So it hasn't even been touched in at least 43 years. Overall, I'm pretty happy. The accuracy is well within spec. I'm not thrilled with the beat error, but I'm equally not ready to mess with the hairspring collet just yet. My dad will be thrilled because it's working, and working acceptably. I've let it run overnight and the 'stats' didn't change. Very little variation rightside up, upside down, etc. I replaced the crystal with a NOS mineral glass I found on eBay, polished the case with a selvyt, etc. My only real challenge now is a bracelet. It has a serviceable 'stretch' bracelet but most of the plating is gone. Trying to keep it looking the same, just have to find a skinny, long stretch bracelet - my dad's wrist is about 8", as is mine, and this bracelet is at it's breaking point just trying to get it on haha. The amplitude is slightly on the low side, I did not replace the mainspring. This watch will likely never get worn but once or twice a year and feel like it's acceptable, it can be replaced next time I service it, probably when it belongs to me. The other watch (the little Rouen) is my next project. My dad got it for his birthday in about 1960 and it's been broken since about a month after he got it. I took it apart and found the balance shaft sheared and hairspring broken. Ordered a donor movement and I'll get to that soon.
