Bulova 11BLC....Where did this come from?

I just took my old Weller soldering gun and turned it into a demagnetizer. Passed the watch through a couple of times and then put it to a stopwatch. It looks like I'm gaining 3.25 seconds approximately per minute.

Well I ran it through the Weller de-magnetizer again, opened it up and saw the hairspring looked kind of off center, nudged1285051583671634958327583f2ea785.jpg it this way and that, and now it appears to be keeping good time against a stopwatch. Finally!!!

Could not have finished it without you! Thank you and everyone else that helped walk me through this. I am wearing the watch now and will see how it goes through tomorrow. Now I am still trying to hunt down parts for the Poljot 3105 movement and will be tearing into an 1890 Elgin pocketwatch this weekend!

Well now im getting slightly frustrated. I wore it through the night and when I woke up at around 7:30, it had stopped at just before 7:00. I assumed that maybe it just didnt have a full wind. However, in the last 1 1/2 it has stopped 2-3 times....not sure what could be causing this. I will say that it is not winding easily. I dont know if that is because something is still messed up or because the crown is so small and I can hardly get a grip on it to turn it.

Hey mcass,

My pleasure to help,

I had a similar problem with one of my bulovas. Once I eliminated any issues with hairspring and gears, I decided to replace the mainspring. Bulova has these "lifetime" springs, but they do need to be changed after 40 or more years.

Apparently they were thinking about horses, that's their "lifetime" (lifespan)!! :D

    • Couple of Oris in there , early Oris were pretty small , around 28mm , the first 2 could be 45x or 49x series calibers. The Unicorn might also be an Oris, to know that these will be pin pallet watches if there is no jewel count on the dial. The other 3 will be much the same. The Oris are ok and have some value, as far as pin pallets go Oris were very good as thats all they were allowed to work with for a long time, so they made sure they got the best out of them. Its good to inside though, at the most basic level of inspection of an Ebay sale at least you can see if anything is missing inside, otherwise its just pure luck. Ask the sell if he will add some pictures of the insde for you to privately look at.
    • What I've found with Facebook groups and yes i am in a few , its good to have more than one source of information on specialised areas such as lathe restoration or just military watches etc. They dont have the same ethics that we have here, we all seem to look out for each other here, a good close knit group that encourage new members and each other daily. We have a laugh sometimes and really help each other out and support each other. All the support i received about my mum was so kind, i wouldn't have got that anywhere else. A lot of these facebook groups are full of aholes and sarcastic gate keepers. I consider our forum to be very unique, but the subject of # if it ever Dissappears # honestly i think does need addressing . We're really just after a connection site Michael not a full function chat group. Just a way to re-connect if something happens. But the other big thing is all the stored information how that can remain accessible. 
    • Facebook is a big NO from me. I have nothing to do with any of these sorts of places. 
    • I for one would have to pass, I'm not joining Facebook. 
    • Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement.  This might be helpful for you.  704789946_TZIllustratedGlossary(2).pdf
