Hudson Dynamic jump hour

Question

 

Got this on the way but as its ticking but not advancing the time, I want to see if i can get a parts movement for spares.

I know it's a crappy movement but I like the case & "dial"

 

Can anyone id the movement?

Its stamped Bader Ltd but Ranfft doesn't list it so I presume it's a rebranded movement.

Its a Baumgartner 866. The reason it is not advancing is because of the drive gear is riveted onto the barrel of the mainspring, and it needs to be tightened in order to drive the hour and minute hands. This is a characteristic problem that is unique to this type of movement in that it does allow the seconds to continue ticking because that gear is directly driven. I'll follow up later with more info.

I'm ordering a new barrel lid from CousinsUK. That should solve the issue, right?

Maybe same problem as i have with a BFG 866 digital . It the hour jumper that is broken. doesn't run either.  it's the part in the middle. Should be twice as long. It's sits inside the minute disc and flips the hour disc when it comes to 59 minutes. was thinking of making the part. But don't know how it should look. So i bought a donor movement. fingers crossed it's okay. Haven't seen any spare parts for the digital jump hour movement except the usual like balance and wheels. DSC00199.thumb.JPG.903b5cd9dfd2dfa6ee4257ad9c3d6f32.JPGDSC00198.thumb.JPG.8d7499537c330718f7a6a8b3fe23d12b.JPGDSC00197.thumb.JPG.59c543589b05fba1bc6a89652a64b6fe.JPG

The drive gear is riveted to the lid of the barrel, so yeah that should do it. You could also take a broach or a staking set placed within the gear opening and give it one tap. It usually tightens up enough to drive the hour/minute hand, but loose enough to allow setting the time.

Thanks but I'm nowhere near handy enough to warrant splashing out on a staking set. The lid is only £6 so I'll just order that once the watch gets here and I've had a chance to take a close look.

Quick question
Is it the lid I actually need or the barrel itself?
I want to add it to other bits I'm ordering to take advantage of the postage. If I get it wrong and have to reorder it will end up costing me loads more, comparatively.

Is it only the digital 866 that has this gear on the barrel or does all 866 have them?

Mostly seen in jump hour, but I've seen this same barrel in at least one non-jump hour with BFG 866.

Went to take the dial off to see why the date won't click over but can't find my smallest thinnest screwdriver emoji35.png

 

They're small alright. I have extras if you lose one!

Thanks. Hope I don't. Will work on top of a cloth so no bouncing pieces on table surface so hopefully that will stop any losses.

Panic over, looks like I got it right

Hmm, my order from Cousins just got here and there's something not right, apart from it is part plastic.

The small cog looks to be a lot lower profile than the original brass version. You can barely see it in the photo. Hope it will work.

Balls!!
While attempting to remove the barrel lid, the mainspring shot out and smacked me on the visor emoji35.png

I give up with this. Gonna look for someone to rebuild it for me.

I ordered two  Cousins mainsprings for a Landeron and both broke after a few hours. When I tried getting a refund, they refused because the mainsprings were from  some other supplier and they could not return them....and so I would have to take the loss, not them. That was the last order I made to Cousins. 

Ok for next time, place  one side of a thin brass tweezers between the barrel edge and the lid to keep that spring down, then open it. I have more barrels and lids if you need one...and I might have springs too. Have to check.

Don't think the MS is damaged, just my visor
Don't think I lost anything. I'll try and find someone willing to work on a pin lever. Really want this on my wrist.

Most watchmakers will not work on a pin lever because although they are simple in construction, they can be challenging to assemble because of the inexpensive method of construction. Before I learned how to do complete overhauls myself, I asked (via email) a well known watchmaker on the east coast if he would overhaul my 17 jewel Sicura jump hour. "That's not the kind of watch I'd want to work on..." was the reply.

Watch-bias and snobbery can be pervasive in some circles.

    • I've never used the Longines archive extract but it has to be applauded for offering this as a free service, I have however used the Omega extract service which has a charge attached to it, that service was also good and included the Model number and Name year of manufacture and which retailer originally sold the watch and in which country. I have also had good experiences with a company called Eberhard many years ago, I needed some parts for a old chronograph I  bought at a local auction  I needed a full set of hands a winding crown, and oval pushers, on the off chance they may still have these I wrote to them with the serial number and received a very nice letter back from them telling me that my watch had been manufactured in 1938 and was a two button 18ct rose gold chronograph and that they did have the parts and would be happy to supply them for 65 Swiss francs. Try doing that with any of the large manufactures, their response was a pleasant surprise. I had the watch for many years but sadly I had it stolen about 5 years ago.
    • Thank you for your introduction and welcome to this friendly forum. Where is NL
    • It's ok if that's how she self identified.
    • Personally I would see if incabloc springs fit.
    • Thanks a lot guys ... I'll do some test and show the results. I really love that dial though it's pretty stained and scratched so I'll try first with Rodico, Q-tips and distilled water and see how it goes. There is no financial risk as I got it for cheap ($40 shipped) but those 1002 dials don't often show up on the net and are sold for much more, even if they are damaged ... plus I have a nice 5500 case that's waiting for a dial    By the way ... did anyone of you ever drilled an ETA 2840 mainplate to make place for Rolex dial feets ? I'm asking because I have the case, the low beat ETA and a handset that could fit but I don't think I could ever cut the feets of a Beyeler Rolex dial
