Question about BFG 582 and 866 parts for jump hour watch


Recommended Posts

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.

    • Sounds great! And yes, I would use grease for the keyless as well although treating the parts with epilame would make the grease less likely to spread in the long run. Not critical but won’t hurt. My current strategy is to epilame treat all parts getting in contact with oil or grease.
    • Hello everyone, for what it's worth, here is my approach: 1. Escape wheel submerged in Epilame, then dried quickly with a hairdryer. Then the final tip of the pivots are cleaned by poking into pithwood. The logic being that the Epilame is removed at the intended contact point (to avoid any residue that may mix with the oil), but remains in the areas where oil is not supposed to spread to (further down the pivot towards the wheel). The escape wheel teeth also benefit from having Epilame to keep the 9415 in place.  2. I use a syringe to treat only the pallet stones. I suspend the pallet fork with some Rodico so that the stones hang downwards. I notably use a rather thick needle where a drop WON'T form, but rather where the Epilame liquid stays in the needle tip, which I then dip into the pallet stones. It requires some practice to get the right amount of Epilame into the needle tip, but it works for me now. This way, no drop will "jump" onto the pallet fork and potentially go all the way to the pivots.  3. I let the movement run for a few minutes without lubricating the pallet stones... to scrape off the Epilame in the intended contact "channel". Then I remove the balance again and lubricate the exit pallet stone with 3-4 successive drops. See the "channel" that forms on the pallet stone in the picture -- not so easy to see, but it's visible.       I am conflicted about the use of Epliame in balance jewel settings. My impression is that the two jewels sufficiently suspend the oil (even 9010). Apparently Rolex recommends NOT to use Epliame there (heard from a former Rolex service center watchmaker), as it could cause additional wear. Apart from that, I follow specific instructions where I can find them. E.g. the infamous Rolex reverser wheels or sometimes (parts of) the seconds wheel. Exception: I'm currently servicing an Eta 2824 and will probably ignore the service sheet that recommends treating the whole keyless works with Epilame and then using HP1300... I'll skip the Epilame and use 9504 grease.        
    • I'm going to give this a try today/tomorrow on my UTC33/Seiko 66, thanks!
    • Hello and welcome from Leeds, England. 
    • Don't forget Mark is a hard working watch maker so he is also tied up with work. I'm sure he is keeping his eye on this forum making sure it is running along nicely.
