Advice on a vintage Bulova

[DelK]

My Bulova Aqua Queen, 1965 vintage with movement 7BPC, has cleaned up well cosmetically. New crystal, and case looking good. I put it on Watch-O-Scope and it is running about 8 sec/day fast, amplitude 334 degrees and beat error 7.8ms. I think this looks pretty good. Is there anything I can/should do for this? Is cleaning and lube asking for trouble? The beat error is higher than I might like, but it winds and runs. Not bad for a flea market acquisition.

Best,

Del

Sounds like you forgot to regulate the watch.

Hi It would no doubt benefit from a clean and lubricate as you dont know when it was last looked at if ever at all. No history.

I'm not sure what the question is if you're very happy with everything?

The lift angle for your watches 51° that's not going change very much at all. The amplitude is too high it should be a little bit lower than that. But it may be high if you didn't follow the procedure.

A procedure would be like this you wind the watch up and you let it run it depends on which manufacturer you look at but usually about 10 minutes to up to about an hour that's considered full wind. You don't normally want to time when you just wound it up tight as it's going to have a little more power than it really needs so wait about 15 minutes then time it. then always good to look at the watch in more than one position like dial-up and dial down should basically be identical. Then one crown position minimum like crown down. It really helps to see what's going on.

As the software you have can capture images it be nice if we could get a image of each of these different results.

thendepends on what you want to do with your watch of it hasn't been cleaned in a long time always nice to do that. As far as putting the watch in beat we don't have a picture of the watch it's a newer watch it has a movable stud you to congest gently nudge it one direction or another and bring it down and beat as that is a very unacceptable number. As a reminder typically the timing machines go to a maximum of 10 and people like to see that number much much closer to zero.
