Question about BFG 582 and 866 parts for jump hour watch

Hi,

I'm currently working on a Majestime jump hour watch bought from a US eBay seller. Before buying, I searched for Google and found it was using EB 880X movement.:geek:

But yesterday I got it and there was a BFG 582 movement!:startle:After searching, I found there're plenty of BFG 866 watch but no 582 watch on website in China. :hot:Of course, there are several suppliers in US, UK and India saying they have 582 parts. However, the postage is twice or more as the price of parts. And as a senior middle student, it's not affordable to buy.:bow:

By the way, the barrel wheel and balance is broken.

So, I come up with two ideas:

1. Using 866 parts

2. Install 582 jump hour parts on 866 movement.

Is it possible?

Looking at Cousins a reference NO is the answer. The balance complete offered are different. Your best way forward is to find a donor movement. There are few balance complete for sale on eBay see below:

Hi,

How about the barrel?

And, maybe I have to make a hairspring adjustment but I don't know how to take the balance apart.

Last, if using 866, can I install the 582 jump hour system on it?

Thanks

Almost sure that it won't work. Not the same dimensions on a bfg866 movement? 

Can take a picture of a movement plate on a BFG866 if that is any help?

It seems that bfg 866 has similar structure of jump hour.

But they don't look the same in any other parts? So my guess is that i won't work? Not even the same size. 

I have a BFG866 movement that i can take a picure of? If it's any help?

Thanks.

However, now it's time to do a hairspring adjutment. If successful, the problem solves. If not, there's exactly nothing to do with it. Thinking a lot, I guess it makes no sense to move jumping hour system to an 866. Maybe replacing the whole movement is more easier.

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
