I picked up this white gold bottlecap Bulova off of eBay with another one in yellow gold. Both were advertised as not working. The one I really wanted was the white gold one with the gray dial. I believe it's a 1947 Treasurer. A new mainspring and a good service and she's looking good and running great. The other one needs some parts as it had some water intrusion in the stem. I can't wait to get that one running as it has a really cool patina on the dial.

Well dang! It stopped after about 45 minutes. The balance wheel turns but the escapement wheel does not advance. Thoughts? What did I do wrong?

If the balance swings but the escapement doesn't do anything, then power isn't making it from the mainspring to the escapement. Something is binding; could be as simple as a small piece of dust in one of the teeth or leaves of one of the intermediate wheels. If it stopped after 45 minutes, it would likely be something in the second wheel, assuming it isn't something as mundane as the minute hand catching on something. Something in the motion works could be it too.

You mentioned moisture intrusion through the stem. If rust damaged setting wheel and/or surrounding, it could be the cause. Clean/polish or replace damaged parts.

That was the other Watch and I bought a donor movement last night on eBay. This watch is in excellent condition. I think a speck of dust got in there.

I'm going to take it apart again and make sure I didn't let any dust in.

It must me a huge speck of dust. :) I have a gut feeling there is something else.

Well I finally got a chance to tear down the watch and noticed one of the train bridge screws was loose. I reset everything and it seems to be working fine now. I have no idea how I missed that.

It happens. I have on watch that would run great, then suddenly it would be overbanked (aka 'out of action'). Finally found the problem - the pallet bridge screw was loose, and so the pallet had too much endshake, sometimes allowing the guard pin to jump the safety roller. I found it when I noticed that in some positions there was a 'ting-ting-ting' sound on top of the ticking.

Nice bottlecap case. Havn't realized yet that I also have one, well, more a cushion-bottlecap combination. 1972 movement 11AOCD. It has a very good date quickset, but also a source of ruining the date disk when you fiddle around with it without knowing exactly what to do and most importantly when. The date disk had to be fixed (the seller honestly mentioned that in his offer) along with a full service.
