Should they be used? Cheap Mainspring Winders - Full review and comparison with the Bergeon Winders

[@flatearthbear4077]

First off Thank You for uploading this tutorial. Secondly, the newer more expensive Chinese caliber specific sets have steel arbors with the appropriate steel hook for winding the mainspring without fear of imminent failure. While of course the Bergeon set is coveted by all, the foreboding price makes them a luxury. The Chinese set I have comes with 20 barrels and arbors that are caliber specific with one handle with both left and right cutouts to accommodate the caliber specific left or right hand winding. These calibers are all specific to wristwatches but for some of the smaller size pocket watches ( sizes up to 10 ) the largest of the winders seem to work adequately. Again Thank You for your video on this topic as I appreciate all the information I can get!

[@Luxury_Watch_service]

Half way through the review, i said to my self "this is the most detailed review i have seen". I also believe that the Chinese will make changes to the tool set, as they improve constantly. Kudos mark, for a job well done.

[@retsamyar]

lol you expect them to innovate... history has shown they will only copy some one else if they need to or start to loose sales... expecting them just make a better product because its good for the consumer is pretty funny though... The ccp has made a culture of cheats and thieves. The chinese could be a world leader if it was not for the CCP. If you are lucky the ccp will fall or another maker gives them reason to better/copy a better design, cause the myth of home grown innovation is again laughable.

[@24hourgmtchannel64]

I was at this cross road a few months ago and I am glad to see this video. I mainly service ETA 2824-2, 2836 and 2846 and was trying to decide between this Chinese set on eBay, piecemealing the Bergeon set one at a time as needed (still most expensive) or buy a used set such as the K & D Adjustable 123X Mainspring Winder Set . I ended up buying the K & D adjustable 3 piece set however the arbor sizes are to big or the back is to small. I also noticed after the spring was wound, it spread the adjustable holder far enough to where I had issues fitting it in the barrel and had to do it a few more times. As a hobbyist, I now think the best option would be to start with buy one Bergeon right handle, and then buy two ETA arbors however even Bergeon is off on their arbor size for example the ETA 2846 is still to big. No perfect solution for a hobbyist on a budget her IMO.

[@tedblack2415]

Oddly enough i looked at these a couple of months ago knowing my hand spring winding to be detrimental to the watch's health & glad to see you covering the subject especially in such great depth and detail, very much appreciated.

[@ichi210]

Mark, thank you very much, as always the video is very informative. As for me, I’m not professional watchmaker, but an ordinary hobbyist. Few month ago I bought the Chinese-manufactured mainspring winder, exactly the same you showed in your video. I’ve been using it for several month by now and I can say that for nonprofessional as me it is quite a solution. Of course if I had enough money I would buy swiss made high quality watch tool, but I don’t have enough money. Chinese made tool provides appropriate quality for the price, in my opinion.

[@lafaina79]

.....what about if you're working on a russian watch, or lower quality than Eta movement for example? Are these cylinders uniquely made for certain swiss calibers only?

[@HarvardBob]

Wonderful video. Thanks so much for explaining how watch winders work in detail. I've watched many Watch repair videos, and they never go into the details how a winder actually works. Agree with you that cheap tools have their hidden costs. I work mostly with fabricating small electronics and there are key tools such as pliers and screwdrivers that I used constantly, and so I've purchased highest quality I can afford. For less frequent tasks I may trade off quality for price. I have had some “cheap” tools for many years because they are infrequently used and I take very good care of them. I think this is an equation that everyone, except those with unlimited funds, goes through when they purchase a tool. Am I going to use this once in a while, or every day? I think you showed, that if one exercises care, a cheap Chinese set is superior to hand winding or just replacing the mainspring. The trade off is reliability and longevity of the tool. For the occasional amateur that might be acceptable. As you go up the skill and and utilization curve you may be able to justify the purchase of the higher quality tool.

[@briansloan3662]

Definitely want to see the Seiko left-hand hack please! I have this set, and because it was cheap I didn't feel too bad about drilling out one of the barrels to accept a different handle with a bigger arbour to suit the mainspring I was grappling with....

[@philedwards2213]

Great video, thanks Mark. I guess if we kept the retainers from new main springs, we could use those to swap a right hand wound mainspring to a left hand wound. Would just need to start collecting the main spring retainers from now on.

I did purchase a set from eBay and while they, too are caliber specific, the set came with only one handle, but more importantly steel winders.

I just got a 20 piece set from Amazon and immediately checked the material used when you mentioned it here... it is steel! Also, I did not know about caliber specific when I bought them, I just assumed they had mm measurements. Darn, you think can I use a caliber specific if it fits into the barrel I'm trying to set a spring into, even if it's not the caliber?

[@GregSherlock]

Hi Mark, Thanks for the review of the cheap mainspring winders. I have pondered purchasing a set of these for convenience over the last year or two however, I think I'll stick to my practice of buying a new mainspring if available although, I have been taking note of the sizes of the barrels I most commonly work on and as a compromise, buy the individual Bergeon winders as required as I don't think I'd use the full set. Keep up the good work!!

I bought the smaller Chinese set a few months ago and as of yet haven't been able to use them; they are always just the wrong size. I've had great success with hand winding though and since I'm not working on anything expensive I think that's the way I will continue until I win the lottery.

@@2Death9 Now those sets are like 45 euros and have steel instead of brass. The "real" stuff is not worth one dime. I personally work in a bike store. Spokes can be different in mm. When you cut them you need to put thread on them for the nipples. Those threads are not cut but rolled(Pressed into shape) and so there stronger. The whole tool solution for just that, costs me 550 euros. Plus the "rollers" wear so 150 every time one is worn. Its insane its this expensive.

[@MarekKorkusinski]

I have bought the cheap set from Cousins. I have the same experience - some of the cranks were left-handed, and some regular. However, the set from Cousins only contains one extended barrel and two rings, sot he waste is minimal. Also, it comes in the box, so damages to the parts in transport were prevented. I attempted to wind one of my mainsprings by choosing the proper set by barrel diameter. However, the mainspring was wider than the little depression in the winder shaft (where the hook sits), so the hook did not lock properly. I could not wind the spring past two or three rotations - as the hook released from the mainspring. This is precisely because these winders are caliber-specific. I suspect that the Bergeon set would not have given me these issues.

[@BruceWSims]

I have been haunting YT for videos on winders for exactly the reasons given in the video. Though I wear gloves rather than just cots, I still had the same issues with hand winding. I Did purchase a used set of vintage winders but had the devils' own time using them as the pieces simply did not want to stay together during a task. This is the first I have heard of COUSINS offering an alternative to BERGERON so I may take a peak there. Frankly, though I am still "gun-shy" about PRC products given the number of compaints I have heard about poor finish and difficulty in interfacing with more mainstream products and tools. (Great Video, BTW 😊)

[@legacywatchguy8333]

I purchased this exact set so I was a little apprehensive about seeing your video..."Did I buy crap?". My set had four broken crank knobs, but the seller refunded me $35 of my $107 purchase price. I'm a hobbyist, but what a found was the set did NOT fit most of the vintage watches I was working on. Has it been worth it? Well, not really yet, and I didn't know the arbors were calibre specific until this video. Live and learn...and...buy more tools. Good thing I like tools...

[@brucegraham7457]

Having restored hundreds of pocket watch movements, I can confirm: Always use a new alloy mainspring, always use a mainspring winder. Hand winding a mainspring will deform the spring, and can put kinks along the length of the spring - both will reduce the effective power sent through the gear train. I use a vintage Marshall mainspring winder with multiple sized barrels and a steel handle that is cut for both left hand and right hand winding. You could probably do the same with the Chinese set. Still doesnt solve the brass arbor issue. Thanks for sharing your videos!

[@giulianosbardelli5166]

good morning thank you so much for the review Mark, I have been using the Chinese kit for several months, I think that for the cost it is recommended, before I used my hands with disastrous effects, but I am only an amateur and I am not a professional watchmaker. I would have loved to buy bergeron, but the costs are prohibitive.

Hi Mark, I bought the set with stainless arbors and other parts, AU$147. Can't wait for the hack vid mate

I recently ordered a set and currently it´s at the customs office at the airport of arrival. I will only use it occcasionally on my watches mainly using ETA-movements. Concerning the brass hook of the winders I also fear that they won´t last very long. I am very excited if the set I ordered will arrive undamaged or not. Thank you very much for your review! Now I know what to expect. P.S. they arrived today and I was very pleased that their arbors are made of steel and not of brass! This set was slightly more expensive than the one showed in this video. But far more cheaper than the Swiss made.

[@andrewpearce2562]

[@apyorbitz]

Thank you for the great video. What does it mean to be calibre specific vs generic? Is it just the diameter of the barrel? Does your generic set just have a lot more sizes? And for hobbyists, is it egregious if you use a winder smaller than the barrel so the spring has to expand when you put it in? I know that is probably not right, but winders are one of those things there I just can't rationalize spending the money and buying new springs can also feel so wasteful if it just needs a cleaning.

[@TexanUSMC8089]

As a hobbyist that wouldn't use this tool as often as a professional....It may be worth the money. I bought a generic Chinese tool kit that may work for a while. At least I hope so. If they fail, I guess I'll be buying a new main spring for my watches. Great video explaining things. Thanks.

[@Diplingdart88]

Thank you for the good video..Please show the left-hand-hack;) I purchased this set myself but it hasnt arrived yet. I was hoping that it would be much more versatile and usable for many mainsprings:( Are there other affordable (chinese) winders out there? Recently i purchased a used and old set of winders, but the steel- hooks were completely or nearly completely gone and useless...and i think this might be a big and not mentioned problem with buying used winders!

[@marcusjenkins]

Excellent. I'm not put off, _except_ my work will be almost exclusively on popular Japanese movements: Seiko 7S26, NH35, Citizen/Miyota 8203 and Orient F6922. I'm prepared to machine new pins for the cranks from, e.g. mild steel. I'd love some viewpoint on how this set might work for me winding the mainsprings on these movements, particularly in relation to the predominantly Swiss movement - specific sizings in these Chinese sets. Thanks, again Mark!

[@T1g3rch3n]

I own both some second Hand Bergeon universal winder and this Set of Chinease ones What I did with the Chinease one is... 1. File away the brass Hook 2. Drill a 0.2-0.5mm Hole in the same Location 3. Take a 0.2-0.5mm blue Steel rod and glue it in place 4. Shorten it until its as long as the original Hook was 5. Polish the end The Set is in Use for 3?

[@chrisbtoo]

Looking on Amazon today, it seems like they've moved on a bit - I'm seeing one with a single cylinder with both regular and reverse slots, that looks a lot like a Bergeon one. Winders for 20 calibres, and the arbor, plunger and arm all look like they're steel (although difficult to tell from the product page). All for about 1/10 the price of a Bergeon set. Who knows whether it's actually any better than the one you're looking at here, though.

Use the right handed but a size smaller than normal then get a washer with an ID just smaller than your barrel.

[@magnumpunch]

Thank you very much for this content. Now I will wait for chinese to pick up the good advices and implement them on the product, then I will buy... Meanwhile more hand winding. By the way, the way I do it is slightly different: after placing the tail of the spring I keep the spring in track and roll the barrel to pick it in... I think it's the best "worst practice", at least it diminishes the cots issue (also I lubricate the cots tips beforhand).

[@infernalchaos1066]

I know I'm late, but I'm interested in the hack for right hand winders.

[@scott1152]

With a generic winder set the easiest 'hack' is to find the correct barrel drum that fits the watch barrel, and then find the next smaller drum that fits into the larger (correct) drum. So if the correct barrel drum for the mainspring barrel is say 10mm, you will want to find the next smaller barrel drum that will fit inside the 10mm barrel drum itself, say a 7-8mm barrel drum. Then wind the spring (right handed) on the smaller barrel drum, and then press the spring into the larger barrel drum - then press the spring into the barrel of the watch. So you just wound it on a right handed arbor and then just turned it around before putting it back into the watch barrel. If that next smaller barrel drum has an arbor that is also too small, well I'm not immediately sure what to do there.. =)

One Bergeon without handle stands you in at north of £60 with VAT, I see these sets are running at just over £100, a price that will likely go down with time. True, the brass hooks could be an issue, but with even the smallest of lathes and careful handwork it should not be too much of a stretch to make steel replacement parts. There's even the fact that the parts of these sets would make a useful start on making up winders for odd movements one might tinker with, so as always with a lot of Chinese stuff these sets have great potential for those inclined to add value themselves. I'd also suggest that Marks excellent video will be viewed by enterprising Chinese eyes, which will lead to steel replacing brass in parts. As probably the vast majority of mechanical watch fiddling these days is by Hobbyists, I'd have to say that the Chinese are going to end up eating Bergeon's and ETA's lunch :)

If you are a hobbyist then replacing the mainspring sounds like a good option particularly on a valuable watch unless you are wealthy and buying a set of quality winders is easily affordable and if you give up the hobby at least you can sell them. On cheap movements I see no problem to hand winding if done with care.

There are many reasons for not doing by hand but I'm guilty of hand winding the mainspring on many occasion. I'm no watchmaker, just a hobbyist. I know when I'm winding the spring into the barrel, dry skin will get in there. What impact this has on the energy reales in normal operation, I don't know. It would be interesting to see the difference.
