I've given up on the idea of a comprehensive, affordable set of mainspring winders. A new spring is cheap and goes in so easily! By no means am I  an expert with hairsprings, but repairing them i

You wouldn't. It's about barrel sizes. The ETA set is sized (and I'm sure labeled) according to common ETA movements. Generic sets are sized by unit measurements (mm). If you do a lot of ETA stuff, it

Just found in a chronograph barrel. Apparenly put in by hand, too ? Frank

LOL...makes me chuckle.  Why.  Well, my dad had four different types of winders in the stuff I inherited.  I really fell in love with the K&D set, but it was incomplete--missing the smallest arbor (which I will likely never use).

The other day, I saw the complete K&D set plus another set on Ebay and, I dunno, maybe after a couple shots of Jameson, I was determined to win that auction.  I did and it cost me $$$.  Now I have winders out the wazzoo.  I will probably put some of these back on Ebay, because I can only wind one mainspring at a time!

So, I recommend the K&D

Hi Allan

I too am short of main sporing winders. I bought a really ceap set from ALIExpress but these are poor quality and I do not expect to get much winding out of them. The arbor pawls are brass instead of stianless and Mark Lovich points this out in his appraisal of this set. I went on Cousins UK web site and noticed you can purchase all the individual items for a full set of Bergeon set of 17. I contacted Cousins to ask if they did just the box that would hold the 17 and I could buy they winders as I need them to eventually make up a full set. Sam Cousins wrote back and said that the box only will be available July. I will definitely be ordering one.  I have already started the collection and have the left end right hand holders. This is a good way to spread the cost and get a quality product.

This is another one I found, looks like Bergeon thing, but again I am not sure if it is suitable for wristwatches:

I own these (but in blue) and they work well for me. They are definitely suitable for wristwatch mainsprings. The handle and the drums are made from aluminium I think, the arbor for attaching the mainspring is made from steel

In my experience (some seven years now, and a few professional level courses at AWCI in Ohio) there is no simple solution to the mainspring winder problem.  I've owned and used the K&D 128.  Not very friendly, but useable for most American PW sizes.  Wouldn't count it for wristwatches -- barrel sizes generally too large.  Also used K&D WW size winders (set of three with variable "barrel" sizes).  These are easier to use and quite useful for older WW calibers, particularly American.  What many folks starting out won't understand is that the winder has to fit a number of different dimensions:  Winder barrel must be just smaller in diameter than spring barrel.  Winder core must be just larger in diameter than spring eye (to assure secure grip without permanently distorting eye.)  Height of winder barrel wall must be close to width (height) of mainspring -- if too high, spring will uncoil inside the winder barrel creating unholy mess and destroying mainspring (ask how I know!) 

Understand that modern automatic mainsprings are completely different animal than old PW or vintage WW springs.  They are much longer (meaning larger diameter when fully wound), much narrower, and generally have much smaller eyes.  Old American winders cannot be used on these without extensive modifications.

Which brings me to solutions.  Currently I'm using a set of generic Swiss winders sourced on E-bay for about $350.  These are identical to current Bergeon set of 17 right-hand winders selling around $900.  Also still using the K&D adjustable set of three.  Finally, using new set of Chinese winders (similar to Swiss pattern, quality not bad) designated for various ETA calibers (also fits some Rolex).  Even with all these options,  creative modifications are called for -- reducing height of winder barrel wall by inserting small washer to take up space, turning tiny ferrule on lathe to allow use of ETA caliber winder in generic winder barrel, etc.

Sorry to advise there is no simple solution. You will likely need several different winders before you're fully equipped.  Best advice is to practice repeatedly with old mainsprings, preferably identical to the one you're replacing.  Make modifications as required, and proceed with that expensive new mainspring only once you're fully confident you have the bugs worked out.  Oh, and don't believe people who say you can do it all by hand . . . best of luck installing 60-hour power-reserve automatic spring by hand without destroying it.  Simply won't happen . . . !

Hello

After trying to find a decent and reasonably priced mainspring winding set (and failing to do so, since the arbors of the set I have are basically too thick) I guess I will have to go for Bergeon. Since I am on budget, I was thinking buying only I need for now.

If I understand correctly, Seiko 5 has several movements (6 series, 7 series, 7s26 etc.) and they wind in both right and left direction (clockwise and counterclockwise).

So, my idea is to buy the following:

Right Hand Mainspring Winder Handle - https://www.cousinsuk.com/product/watch-bergeon-handles-for-winders

Right Hand, Ø10.80mm (No.7) Winder - https://www.cousinsuk.com/product/watch-bergeon-winders-by-size

Left Hand, Ø10.80mm (No.7) Arbor - https://www.cousinsuk.com/product/watch-bergeon-arbors-for-winders

This way I hope I will be able to wind both 6 and 7 series of mainsprings of Seiko 5. Is this going to work?

Since I am in Germany, I guess the best way would be to buy from Cousins. Anybody has an idea where to buy this here in Germany?

Thanks.

If you are on a tight budget you could just purchase a new spring which many horologists do as part of the service charge anyway. If I have a criticism of the new Bergeon wonders the shafts are a bit fat. 
Cousins offer the complete barrel and spring for approx £13.00. If you want just to change the mainspring you need
GR 2378-X Cousins approx. £10.

Thanks but I would like to try to service them anyways and and start building set.

The main question is if I buy left hand arbor and put it in right hand winder and into right hand handle, would I be able to wound left direction mainsprings (for example, series 6 Seiko).

Your are not the first one to ask here about taking apart and replacing mainsprings on Seiko watches having a "sealed" barrel, lubricated for life, and sold as a complete unit only. 

If you read the various topics about that you will find how the outcome may not be the desired one, as in experiencing performance degradation in amplitude and/or power reserve, even when fitting a new mainspring which is close but not exactly matching the original. Issues that then no expensive, specialized lubricant can fix. 

Of course I know well that for one side anyone can do as he pleases with his time and money, and for the other it happens often that beginner have pretty well formed opinions even when contrary to common advice. 

So if you're OK with spending more in tools (which have no other use but for some Seiko's) costing more than a brand new Seiko mov.t, welcome to go ahead and please post on how it goes.

Hi Guys

At an auction recently I purchased a box of watch mainspring winders which cost very little money as most people did not know what they were. Now not having done any mainspring work yet I thought I would try them out. The K & D 126 is complete but can anyone give me advice on how to use it please? I know that the right size  winder fits into the end of the little handle and then there is a little rod and extension piece? which go through the handle to push the spring out so the question is how does the little crank handle wind the spring in as its a very loose fit. The other item in the auction was not named but consisted of a tube with finger grips. ten different size winders and ten different crank handles. Any help would be appreciated

Chris

I have the same one. Just picked it up for $18. It also included a few other pen type winders as well. ( Not by the same company but made in France. The principal is straightforward with these. The different winding dies, lock into the extractor real simple. You just have to know which way the spring goes in.

Here is another set that I am looking at (see below).  Any advantages or cons to using the KD 126,127 or 128?  It looks like the only difference between the 127 and 128 are the barrel sizes they'll accept.  The 126 is the "Robbins Type" but I am not sure what the significance of that is.

Thank you!

Hey!  That's my set!  Well, one of them anyway.  I use the K&D Robbins type mostly for pocket watches.  It works quite nicely and I'm rather fond of it.  It can be used with larger wristwatches but anything midrange or smaller would need a set with smaller barrels (which is my other K&D).

Question for people who work with Seikos: series 6 work fine with left handed nr. 7 bergeon arbors. I read somewhere series 7 use left handed nr. 6 arbor. So I am little bit confused since I am not sure should I buy left handed nr. 6 or nr. 7 arbor? Thanks.

Hi Guys,

I am looking to invest in a used mainspring winder for pocket watches.  I've researched the issue online but it's still not clear to me what all the options are that might suit my need, which is to be able to wind springs for the most common pocket watch sizes from size 18 down.  I'm looking to spend under $200.  Answers to my specific questions/assumptions or general input on the best set to buy appreciated.  Thank you.

 

Watch craft: this has six barrels and two winders.  It (the ones on ebay) says "pocket" on the box cover and I assume that is the model for pocket watches, not the model for wrist watches.  Is that correct?  Does this cover up to size 18?

 

K&D 125A:  This one requires to be placed in a vice which seems a bit more cumbersome.  I'm not sure what the difference is between this one and the KD 128.

K&D 126: I've read that this may not cover size 18.  is that correct?

K&D 128: This one requires to be placed in a vice which seems a bit more cumbersome.  I'm guessing a full set will do most PW sizes including size 18.

Adjustable: this is the kind that I've seen jdrichard use on UT.  I'm not sure how the sizes work and what is considered a full set for pocket watches.

 

Any other I should consider?

I practically specialize in pocket watches. And I use my K&D 126 for nearly all of them.  The largest barrel worked for my size-18 Longines, but I do not know if its size of barrel would also be typical of American size-18s.  But even if not, it will cover a lot of ground and it works rather nicely.

Hi 

At this point my main problem to service a mouvement is the mainspring. The options excluding service by hand of course are:

  • Difficult to buy a new mainspring on ebay and waiting to receive it (weeks)
  • Very expensive Bergeon set like the 5356 => 1050 pounds (ouch!!)

So I bought a Chinese set like you know for ETA the main problem for me it's that I don't have a lot of ETA mouvement so at this moment the issue most of the time is that the arbors provided are really to small so they don't catch the spring => useless.

My idea is to buy just a bergeon by size like these and using it with the Chinese set.

So my question do you think it'll work ? and if yes what size should I buy 4,5 or 6 

Thanks and hope it would help other people struggling with this mainspring winder

I have several sets of winders. My favorite is the K&D set (picture I got off the interweb--too lazy to shoot my own).  You can find these from time to time on Ebay.  Not cheap.

Yes I saw these but are they ok for wristwatch I thought only for clock. 

Do you know if these are ok ? https://www.ebay.com/itm/373549560649?hash=item56f949f349:g:G04AAOSwHYdgf0pZ
