Chinese mainspring winders interchangeably

Ex. 8200 one can wind a Seiko 7009.

Well, if it can wind a 7009, then it can wind all 70xx (7005, 7006, etc) and also the 7S26 and 7S36 at least.

For the Seiko 66 and 6602 I use the same Bergeon winder that for the 70xx, but it is almost too big, so if the chinese 8200 is exactly or smaller than the Bergeon #6 then it will probably work, if it's a bit bigger then it won't.

I thought it might be helpfull and answer your question at least partially.

Thank you friend, but that spreadsheet does not show which others calibers mainsprings the winder can wind in addition to the one specified.

Good to know that! 
I’ve ordered Bergeon 5,6&7 in order to solve the problem of the thin axes of Chinese ones.

The caliber could be considered irrelevant as long as the winder fits the mainspring barrel and the winder arbor fits the inside of the mainspring correctly. There is no standard or easy interchange in this.

Yes, Tom I know, that’s why I wondered if there’s any kind of interaction between Bergeon and Chinese ones…in terms of barril yes but the Chinese arbors are too thin to fit

As far as I am aware the Chinese ones are copies of the bergeon specific caliber winders. Bergeon do make general and specific mainspring winders, perhaps that causes a bit of confusion all around.

That's the problem with the Chinese sets, they are caliber specific.  I wish they would copy the generic Bergeon winders.  When I found a barrel that would work, it would not fit the needed arbor size crank.  My solution was to modify some of the Chinese winders to make them equivalent to some of the Bergeon generic winders, by drilling out the barrels to accept larger arbors.  Still, I was missing some larger arbors.  So, I bought the Bergeon #6 and #8 arbor cranks (far cheaper than buying the barrel and arbor combo).  That gave me arbors of 3.0 mm and 3.5 mm, respectively.  Then I drilled out some brass washers to use when I need a right hand wound spring but only have a left hand arbor (or vice versa). So, far my modified winders are working for what I need and I spent far less than for a Bergeon generic set.

    • As you are looking for a solution, keep in mind that you can order (or salvage from old crowns) male split stems with different length shoulders - the cylindrical section between the threads and the split coupling. The shortest are less than a millimeter, which gives you another variable to exploit since that would seem to be shorter than what you have in the picture. In their repair kit Benrus sold male split stems in Tap 8 or 10, with shoulders from 0.33-0.085 inches.
    • Nicely done. Looks good. Be cheaper than a bought one. More satisfying as well.
    • Yes well the 6497 spec sheet did mention epilam but I don’t have either the product or the bottle for it.   
    • Hello from Nashville TN!!! I’m new to the watch repair world, but I’m nerdy and loving it! I’m helping a friend out and repairing his old Benrus Square Rigger. Basically the crown was damaged (the internal pipe was bent badly…I tried to straighten it and it broke.) Anyways, I’ve learned a lot about this watch but I need some help  it’s a split stem system and I was able to source the correct stem. What I know so far. It’s a split stem, male side screws into the crown. 5mm crown. Tap 9. 2mm tube on the case. I bought a random lot of vintage crowns and was able to make one of them work. It’s the crown on the left side in the pic. The problem is, I need a gold one! I need to find a crown with a recessed “pipe.” The gold one on the right, that has a flush pipe will not work…regardless of how much you trim the stem. It’s has to be recessed like the steel one. I’m just not sure how to search for that!
    • Yes, it's a problem if you're not familiar with them as a 3rd tier brand with 90% of the cases being monoblock, especially if you get one of their chromed cases with faux joints like you ran across. The Benrus and Belforte watches (1st and 2nd tier) more often than not had some opening instructions stamped on the front loading case.  It is easier to tell when you get one of the Sovereign anodized aluminum one-piece cases, especially in Hot Wheels purple!
