1956 Bulova President 10BU movement work in progress


Recommended Posts

Just got this lovely little lad. Only just started researching, but thanks to @GuyMontag's suggestion, it appears to be a President. This thread at MyBulova backs that up.

Edit: also this thread at MyBulova that Guy linked, describing the "President P" variant. I haven't been able to find any other pictures or advertisements or mentions of the charcoal dial on the internet, but my Google-fu may not be strong enough.

It came to me fully wound and not running. Found some corrosion by the stem and on the crown wheel, so we'll have to see what's deeper inside.

Giving the balance a little push, it seems to want to run, but it feels gummy. The last Bulova movement I worked on had the lubricant in the jewels turn rock hard, and it felt exactly like this, so I'm hoping a good cleaning and service will fix it.

The face is in pretty rough shape around the diamonds, and I think I spy a fingerprint or two.

Corrosion doesn't seem too extensive. Other than the outer half of the stem, the keyless works look pretty good. There's some on the center wheel arbor, which may need replacing.

Someone scratched "8020" into the back of the dial.

Lots of side shake in the barrel bridge. Going to have to close that hole up. Definitely going to need a mainspring.

Overall though, could be worse. I don't see any cracked jewels or anything alarming. Yet.

Finally got back to work on this one, and boy did it clean up nicely. Only part replaced was the mainspring. It could probably use a new stem, and I lost the little spring on the stem during cleaning, but otherwise just cleaned and lubricated.

I polished the crystal with red rouge, then automotive plastic polish, and the results are nothing short of stunning. Despite the dial being a disaster up close, it really looks great on the wrist.

    • Could you share the like from Amazon where you bought this? Thnx
    • Very informative thread! After reading through, I ordered a lamp from Amazon. Under $49 US (£39) tax shipping and delivered in 6 hours, yep! This one has 5 intensity levels and 5 color settings from 3200 to 6500. I use a binocular microscope and have the gooseneck lamp in case I need directional light. Don't mind the clutter of watches, those are usually moved off the bench when working on a watch. This really lights up the area nicely. The ring of leds on the binoculars is fairly cool when compared to the new lamp. I like it because once set it returns back to the setting when turned off and back on again.
    • So fsr as assembly, I don't think you would find 5646 different from 5606, just that GS is 36000 beater. No unknown chalange is there as long as the escapement reamins undameged. Rgda
    • no, I have no alternatives and don't know of any. I've bought Mobius and that's all I have. 9010, 9104, 941, D5, 8000 and Moly-Kote.
    • I've just had the wood stove door seal replaced. I was hoping not to need to do that again for a few years. In the name of science I can't say I'm not tempted. I mean how dangerous can it be? Says the man who encouraged his friend the plumber to use phosphoric acid to dislodge the solidified sodium hydroxide that had blocked the bath U bend. We did take that outside first though, and yes, adding concentrated phosphoric acid to sodium hydroxide crystals and drain sludge is as bad an idea as it sounds.. so we did it several times, laughing like delinquent school boys until the explosions of brown goop stopped. The operation was a success, but sadly the patient died (or rather, melted), and we had to replace the U bend anyway.  Children, please don't try this at home.
