Mainspring winders


Recommended Posts

Great Post will follow your examples I have had the same issue you encountered. Also I found with the new Bergeon winder sets the gap that accepts the spring when winding was too small and had to file wider.

PS  are the bushes removable so you can use the tool as originally intended if needed.

 

PPS. Poor design from Bergeon considering the cost

yes, the bushes are removable. There is no problem if the disc is larger then necessary - plus you have the other arbor (as I mentioned above, you have two identical arbors for each two consecutive barrels - you only modify one of them).

The tool can definitely be used as originally intended with no problem.

I could not find those arbor diameter sizes anywhere so that is really useful. I had the same problem with no winder for Landeron 48 etc so just started to make one. Waiting for a 1mm carbide end mill to arrive from China to add the hook piece, and a M3 die to finish winding handle. The winder bit is going to be Nivarox style as this is what I saw to copy, but if that does not work the spoke type looks probably easier to make. Not sure if it is going to work, but cannot really see why it should not

Hi guys, I'm currently following level 2 of the repair course. I split the main spring barrel and removed the spring but didn't realise until the assembly lesson that I would need a winder to install it. Now considering the 6497 is probably a movement im not going to work on too often I don't really want to buy a winder and I'll probably just buy another clone movement which is cheaper than the tool itself.

Now this got me thinking, when you service a watch movement do you just replace the spring for new or do you do as per the course? A full set of winders could be near £1000.

I'm just doing this as a hobby as im interested in watch movements and I only have a limited variety from my personal collection of watches, I'm always buying more watches so I could have a few of each of the following 2824/2840/2836/2892/7750 and a 3135.

I eventually bought some second hand winders. The vast majority of watches I repair are 11 - 13", which means the barrels are all similar in size, so I don't really need that many. I think hand winding is ok if you are careful; you can prove you are doing it well by removing and reinspecting the spring for deformation.

Mainsprings are a PITA for me. For manual winders, you can do both hand winding and using a winder to great effect. Although, if you don't want finger oils on the mainspring, winders are the way to go. I find my latex cots frequently get stuck in the mainspring.

For automatics, you probably want a winder. Its not easy to start hand winding an automatic mainspring with that bridle attached to it. At least for me I didn't find it easy.

As someone else pointed out, a set of vintage is the way to go. You can find them easily under $50 for the two most common sizes.

Search your favorite online auction site for a second hand set, they do turn up every now and then.

For some older watches you cant find replacement springs easily so you do need to use the spring you took out of the barrel.

You can get away without a mainspring winder, but the chance to damage the spring is much higher, so its a worthwhile investment.

My advice is to buy a replacement mainspring for the 6497. They are about £12 at cousinsuk.com. I did the course myself and that's what I did, and if I remember correctly, Mark recommends replacing the mainspring as a best practice, if possible. However, if you decide not to replace it, I really think it is possible to get away with it doing it by hand. It's a big spring so that should resist more, but on the other hand, as it is bigger it should make it easier to handle by hand.

oldhippy, how often do you destroy/kink your mainsprings replacing them by hand, and how much of "a pain" is it?

I’m retired and have been for many years. I do not think I had any trouble, because the springs in watches are of very little height you don’t distort them, unlike clock main springs.

I've been scouring the internet for some mainspring winders that were in my price range and came across these little gems. Strangely enough, it was advertised in Polish and again in English which were both on eBay, but not listed as 'mainspring winders', they were listed as 'GB Federwinder' Maybe that's why they were still on sale. It appears too good to be true... Anyway, the English advert was £20 more than the Polish one, even the postage was more, needless to say, I bought the Polish version! ;) for what I think is a draw dropping price of £125 inc P&P for 18 mainspring winders! Right place at the right time, I suppose...

I actually managed to get a 9.5mm mainspring into an adjustable winder that technically only went up to 7 mm. Jeez... that was a struggle but it worked a treat. I'm getting a feeling that these winders are going to make my life a whole lot easier!

So, I'm still struggling with this.  The inside diameter of my Elgin 18s mainspring barrel is 14mm.  So, that means I probably want #9 (13mm) Bergeon winder no?  Then I need a handle and arbour correct?   I think I want it to be left handed?  I don't know?

Hi All

I've made reasonably good progress at learning this as a hobby thanks to lots of help from forum members.  I'm outright failing on mainsprings though.  My $28 Seiko 6119A MS replacement went airborne when I didn't push it into the barrel correctly.  I bought a new one for the seiko and others because I don't have a winder.  I've long given up trying to hand winding automatics.

I picked up an old winder set on ebay.  But, most of the hooks are broken off making it useless.  The Bergeon winders are priced for professionals.  What do most hobbyist use?  

Any advice is welcome!

Charlie

Hi Charlie   What I use are my hands and plenty of patience The latter being the watch word excuse pun. usually when new springs arrive they are held in a former and once the orientation is sorted out place the former over the barrel making sure the spring fits in the rim then work the spring into the barrel. To make it easier what i try to do is, on a flat surface press the former down a bit on the spring so you have an edge this edge is the bit you fit into the barrel prior to fitting and pressing it into place. If you remove springs by hand and intentd to re fit clean the spring in alchohol and relube. Best to use rubber or latex gloves to avoid sweaty fingers marking the spring. Probably not the correct way but it works. otherwise use a winder. there are several types as you have [probably found out.

How do you keep from permanently bending the bridle on an automatic??

You aren't the only one to ponder this.I recently destroyed a Seiko mainspring trying to get it back into the barrel.The bridle just did not want to go back.I would have had better luck trying to drag a dog into a haunted house.The advised hand wind method works great on unbridled mainsprings.But for a Seiko automatic you need a witch doctor.

    • Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!
    • Happy to have helped, great way to start the day with a win! 🥳
    • Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor. 
    • I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂
    • Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
