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.

Sorry to revive this old thread, but I could use some help.

I noticed today that the movement is loose in the case--when I wind or set the time, it wiggles the whole movement.

I'm not super experienced with front loaders. Is the friction between the dial and bezel what's supposed to hold it in place? It doesn't seem like there's enough here.

The movement ring on the back is free to spin in the case back, but it seems trapped in place (I haven't tried to force it out).

Edit: my other thought is looking at this lip on the movement ring. Is it possible the ring is supposed to go between the dial and movement? I'm still not sure how that would hold the movement in place, though.

Oh wait, I just remembered something. There was a spring on the stem when I got it that somehow evaporated during cleaning. Could that be what keeps the movement centered? Seems weird, but I guess anything is possible.

If so, where does one find such a tiny replacement spring?

Looks like a one-piece case to me (monocoque).  Perhaps there was a reflector ring that interfaced to the bezel to hold the movement in place.  I cannot find this case in the Bullova Case Parts Catalog.  I do not see a movement number stamped on the inside where I would expect it.  If there is a number (not visible from the pictures) post that number.

This watch has a 1956 date on the caseback which is before Bulova started using case numbers so it won't be in the case parts catalog. I don't have this watch but I have a handful that are somewhat similar.

None of them have a moveable ring like on yours. When the movements are in the case they are somewhat difficult to get out, I have to pry them up to get them to pop out.

That definitely does not describe mine. It just falls right out the front.

If I get some time tonight I'll pop off the dial and see what I can discover. Thanks for the info!

I do not know the official meaning of "front loader" but when I use the term, I mean that there is no back that can be removed.  Many pocket watches come out the front even though the back can be opened or removed.

Please, no offense, but it is "moot" and not "mute."  A common error.

You are correct and something I  once knew.  No offence at  all.

    • Hello forum, i have some things i would like to say today if thats ok. Being here is something of a sanctuary for me, talking about something that i love doing with folk that i have become fond of ( yes quite surprisingly under all that craziness and verbal brawn lays a soft heart of gold 🙂 ). I imagine that the same can be said by many of you , a certain number of us are here daily both learning and offering any advice that we are able to. Quoting our experiences both successful and failures for others to learn from. For me at the moment just making this post is a distraction from my current bubble but also from the world around me for various reasons.  Its a place not just for teaching and learning but to make others laugh and smile and be part of a community. I would even go so far as to say we are a team, supporting and encouraging each other when needed and when we are down, my own situation with my mum being a perfect example of everyone's kindness. Thats the soppy bit out of the way 🙂. So my mum has been moved to a brand new facility after making amazing progress with her speech and word recognition in hospital ( poor mum has had to suffer my company and my teaching to the full extent of her visiting hours barring one day off for me that my sister insisted upon ) her consultant calls my mum his medical miracle 🙂, and will be starting her intensive speech rehab today after her initial assessment. Things I've learned about having a stroke, and I'd really like everyone to take note of the causes and outcomes of having one. Please do your own research I am a joiner and not a doctor 🙂, i just want to make everyone aware and just get checked out if you notice anything in yourself that you are unsure about, any risk of having one can be reduced with either medical intervention or/and a change of lifestyle ( which would be my own preference in an attempt to limit my risk, something i have now noticed in myself ). I do know a few of you here have experience but this is what i have become aware of and how it has affected my mum and me. First i want to touch on the effects of a stroke, not only to the sufferer but to the whole family, we all know how dementia affects lives. A stroke effecting language is almost instant non aggressive dementia. Like being in a foreign country where you can no longer read, write or speak to someone without some form of very basic sign language gesturing ( when annoyed i think everyone understands the middle finger ). But a stroke can affect movement ( fortunately my mum is virtually unaffected with her mobility, the nurses can't believe she is 87 and just had a stroke, she's like bloody Supergran, in fact she is a great great grandmother to 2 toddlers ) . Improvement after a stroke carries on for years afterwards, but from what i understand and now believe after being with my mum almost every day since it happened for 7 hours a day, language rehab should be started as soon as possible when the patient is out of danger and physically able. The brain is ready and set to go and rewire itself soon after injury, in a similar ready state to young children ( when we say kids brains absorb information like a sponge, thats pretty much true in early stroke patients) After the first few weeks maybe a couple of months things start to slow down and lesser progression carries on for the years following . After a day she could manage only one word, which was my cue to get on her back and start pushing her progress. Day two i wanted to see how capable she was so i had her writing on a whiteboard ( it wasn't great tbh ) . Day 3 and until she left the hospital most time with her was spent on picture/word recognition on my laptop, picture books, some writing and teaching her to play cards again ( i refrained from gambling for real money, though i was tempted, as I'm  pretty good at poker , she has a few bob and i have space for another watchmakers lathe in my watchroom 🙂 ) Now i suppose i have to back off as the rehab place is fairly intense focused and visiting times are crap as they interfere with all the physio and rehab going on . So i only have 2 hours max a day with her sometimes only 1 if her grandkids want to visit, but she is in good hands and i know she will get as much help as she needs , and as difficult as it is to admit i probably need a bit of a break and distract myself. I'll end this post for now but i want to come back and talk about what caused this and hopefully remind some of you to think about how we live , what to do in the event of a stroke and how we can lower our risk. I'm not a pussy by any means and very little frightens me, but seeing this first hand has put the fear of god into me if i ever had to suffer the outcome of a stroke. My mum is a tough old cookie and i imagine i will be just as tough, but watching the frustration on her face when trying to communicate completely tore my heart into pieces.  Please dont let this happen to you, do everything you can to avoid it, I'll come back soon to talk more about as long as everyone is ok with it, take care for now x
    • The fact that you have witnessed coils of the hairspring clinging or sticking together explains why the watch is running so fast.  If you reduce the length of a hairspring, the watch will run faster. When hairspring coils stick or cling together, this effectively reduces the active length of the hairspring, so the watch runs fast.  As nevenbekriev has said, the most likely culprit here is oil or other contamination on the hairspring causing coils to stick together. Cleaning the hairspring as he describes will solve the problem. Occasionally the contamination causing the hairspring coils to stick can be very stubborn to remove, in which case I suggest ultrasonic cleaning in acetone, naphtha or a commercial watch cleaning solution. Magnetism can also cause coils of the hairspring to stick together, if the hairspring is made of an alloy that can be magnetised. Finally, your watch has what is called a pin pallet escapement. They are considered to be less refined, but quite rugged compared to a traditional Swiss lever escapement. They are quite forgiving. They do require lubrication, if you haven’t done so already, find instructions for lubrication of these escapements to get optimal performance from this watch. Hope this helps, Mark
    • Murks, In theory, yes. For example I have a Seiko dress watch (dress style case) with a 6309 movement in it which I would not take diving, similarly, I have a Seiko divers watch with the same movement in it (6309) which is a diving watch. The only difference is the case (and crown sealing system), the diving watch case is made for diving due to it's more robust seal system on the case and its a more rugged design. Seiko 6309 divers watch: Seiko 6309 dress watch:
    • I mean let's say a was to make a dives watch is this mean as long the case is a dives case and a fits the movement it should be ok and is this means any movement longs it fit the dives case?
    • Whether my post is pinned there or not, I agree the “Lubrication Techniques, Oils, Greases, Epilame Treatments” forum should have a pinned post explaining why automatic oilers aren’t good for beginners, and better suited to production and service environments where many of the same calibre are lubricated regularly.  There are so many other tools a beginner should buy before automatic oilers, and it’s so important to learn to oil properly by hand. So many beginners and hobbyists have no idea how to apply the right amount of oil to each pivot, and just put some oil (usually too much) in every designated location and call it good. Not through carelessness, but through not knowing any better.   Mark
