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

Without the tech drawings showing the part dimensions or the moments to compare it is not possible to be 100% certain. My suggestion is to find a donor movement.

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.

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      By VWatchie · Posted

      Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.

      I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.

      Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.

      Broken watch stem in watch crown

      If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
