The final result: the #7 barrel with the bushes and the #3 arbor with the large disc. And it works great - I just tested it :)

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.

I’m probably going to get crucified on here for saying this. I could never get on with watch mainspring winders. I found them awkward to use due to me mainly being left handed.

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?

Some repairers just replace with a new spring as part of the service. I could not get on with hand winding so I have purchased several winders over the years., However as oldhippy says they can also be troublesome.

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.

Thank you for all of the replies.

As recommended, I think for the 6497 I will just buy a replacement and I'll buy a winder to suit my other watches.

Would the Bergeon winders be recommended here? Should I consider any other style or brand?

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.

    • just a reminder about this test is it's not a perfect test it's a quick test. In other words you can adjust the banking pins that are both the same and visually this test will pass everything looks the same but both banking pins can be in the wrong place. although the majority of time when people are playing with banking pins I don't put them in the same place. one of things have to be careful of is I believe some of the pallet fork measuring tools that actually give you the roller jewel size are actually size so that I get confused? What I mean by this is if you inserted a whatever size in and are always told to go a slightly smaller I thought that the gauge itself its number corresponded to give you the exact number. So a lot of it depends upon the gauge itself I think you do want the roller jewel slightly smaller because it does have to fit in the slot and it does have a little bit a play. But if it's too small you will lose energy so does have to be sized right. Oh other things to check is? I'm attaching an Elgin sheet on checking the escapement I've seen references in the past to making sure that the slot in the four corn is nice and smooth and apparently you can end up with a rough slot and then the recommendation is to polisher clean that up. Not sure how well that's really going to work even if it has been the recommendation of other reference materials. yes art full plate watches fun when they don't work. This is where it's nice to have another set of eyes sometimes as maybe they'll find something you didn't  although that can add other issues. The owner of the shop provides himself on his skills of so now two of my watches have relocated to his bench to solve problems both real and imaginary I'm sure that will get fixed eventually hopefully. But still sometimes another set of eyes might see something that you're not. yes this sort of thing can be quite frustrating. Also makes for an interesting problem unless of course you're the one trying to solve the problem that it's a Escapement Elgin setting up the escapement.PDF
    • I’m not to sure mate! I’ve sent a picture! The crown is off a Tissot 1853 automatic limited edition T115427 A GP19 moto go watch!   
    • For years and I'm still using it I've been using something called SeaMonkey? It's a Mozilla product Basically outscore its Firefox plus an integrated email program. But not the same problems here a lot of times when things are upgraded they tend to be now aimed at very specific browsers like Firefox so I've had to switch to Firefox to respond to any of the messages on the group. So yes they do seem to be getting more browser specific and that may be a reason for others having complications especially if whatever you using hasn't been updated. So yes the world is getting more browser specific perhaps for security reasons. Even though I use a product that is updated on a regular basis is still has problems. So whatever you using for browser should be up to date and if is not recognized it's going to be a problem.
    • I did remember to ask at work and minor complication? Well I suppose technically two separate complications. First off glass mineral glass versus Seiko's Hardlex Glass. Don't know if other companies have their own class or not and a basic class for crystals is probably not the same as window glass it would be more transparent. It becomes obvious if you're looking at a sheet of flat crystal glass versus window glass it's definitely more transparent you can see it when you look at the edges of it window glass looks green. No idea how that changes physical characteristics other than optical. Then we also have thickness like the Seiko five's there crystals are really sick compared to other things and I'm guessing that makes things different. In the first link it talks about Sapphire versus mineral glass. One other thing is bothering me though when I'm reading this is where is the source material? What I mean by this is could we end up with multiple generations of salespeople quoting the same sales tactic or information and we don't actually know because you don't have a source reference? Let me quote something off the website it's brittle oh dear I was sad? Except it's not immune to damage it can crack where shatter under extreme force or impact. So what is the definition of extreme force or impact? Then is that more or less extreme then mineral glass?  Then regarding the price difference while back I had asked the owner where the Sapphire came from and basically wherever he can get the cheapest. So typically ordered from a variety of online supply watch parts in the US and  aliexpress China.. Then yes it does make a difference because we go through a lot of glass crystals and sapphire https://thehorologylab.com/sapphire-crystal-vs-mineral-glass-which-is-best-for-your-watch#google_vignette Then I guess one is glass not glass when it goes by another name? Hardlex Looks like it's purely a Seiko product but now I wonder if other watch companies have their own special glass? I didn't remember from past experience my favorite was people exposed to welding you can find little blobs a metal stuck to the watch case the crystal still intact but there's little burnt holes were bits of metal had actually burnt into the crystal but it was still there. Okay website below starts off with Sapphire sounds good but Apparently it can shatter easier then Hardlex. https://theslenderwrist.com/hardlex-crystal/ One other thing is what I'm reading to websites would be back to I want to see the test results? Often times weren't looking for a subject will find websites where I basically called them these are better than that by the way but sometimes I'll find websites that I will call book review websites were basically the review other websites other material and don't really introduce anything new to the subject. As I said these websites look quite nice which is why I'm giving you a link but where's the test results the definition of extreme how extreme to break a sapphire versus a glass or Hardlex?
