Mainspring winders at an unbelievable price

Always on the lookout for low cost watch repair tools I stumbled across this listing

https://www.aliexpress.com/item/1005004628144533.html?spm=a2g0o.store_pc_allProduct.8148356.71.174f4787pUZBWU&pdp_npi=2%40dis!GBP!£36.29!£36.29!£36.29!!!!%402100bde716700878353065703e5863!12000029892500559!sh

A set of 10 mainspring winders with steel arbours for a mere £36.29 plus VAT and shipping, these have to be the cheapest set around, anyone tempted 😉

They are for specific calibers, the listing says -

3135/2892/2824/7750/2671/2000/8500-1/8500-2/C07111/2235/8200

So, for instance, ETA 2892, 2824, 7750, Miyota 8200, etc. 

If you wanted to you could probably look up the specs for each movement to get the barrel ID,  and the wind direction.

Welp, I got the cheap set in the mail this week, and I also got 4 spare seiko 7009a movements for parts, so a good time to break some more mainsprings.

They aren't bi-directional although I initially thought they were.

As said above, they're definitely made for specific calibers, and the closest I could find for the 7009a barrel was the miyota 8200 set, which is honestly probably too small. There's another set where the winding barrel sat exactly on the mainspring barrel, not inside it, that might have worked, but it seemed like a recipe for disaster.

That said, I managed to obliterate one mainspring through my own inexperience and testing/practising. But the next mainspring I happily got wound up and back into the barrel.

Good enough for a hobbyist I'd say.

Hi all, newbie here.

Could someone who has a set of "value" mainspring winders make a list of diameters and winding directions. Looking at the supplied handles, they all look like RH wind but some of the movements listed would require LH winders.

I work mainly on old Swiss movements as a hobby. I need to decide whether to buy a starter set or 2 or 3 individual Bergeon sizes  in RH and add as I go along. 

Thanks all.

I went with the individual Bergeon components.  1 handle (works for both LH & RH), 1 winder per size (works for both LH & RH), and individual LH and RH arbors for sizes as needed.

The arbors are really the only thing that is truly LH and RH.  The winders and handles can work for either direction.  I've found that 95% of the watches I've worked on thus far (not too many but a good amount for a hobbyist) have all worked with either a 5, 6, or 7 size.  There are a few oddballs along the way where it required a certain size winder, but the arbor was either too big or too small, so I wound those by hand.  For the most part, I find getting individual components to be a much more affordable way of getting good winders without spending the outrageous amount of money it would require for a full set, of which I'm guessing several would never get used by a hobbyist.

Coming back to this again.

Can you tell me if the arbor shafts are interchangeable with the barrel part.        Or, are the bores matched to the shaft diameter for each caliber. I am looking at the diameters of the barrels and, if the shafts were interchangeable, it would give a good selection of barrel/arbor combinations.

The bore diameter is matched to the shaft. 
Overall quality is decent for the price. 
Will still buy Bergeon winders as the need arise (have #1, #6, #7 so far) but this is a nice variety to have. 
I originally bought this cheap set for the smaller arbors, to use with the #1 Bergeon drum. Usable but didn’t solve my problem with winding the 1104A mainsprings.

What is your go to source for buying the individual Bergeon tools.  I found the main Winder Handle as they refer to it, but can't seem to locate the individual winders

Cousins have them.

Both Cousins(UK) and Otto Frei (USA) have individual arbors and arbor+drums

I recently watched this video about that same winder set. It's really affordable and looks quite good, if only I had the information about the diameter and wind direction of those units...

 

 

.

Sizes mm

Left to right top

2000 = 7.2    2671 = 7.1    2235 = 7.8    8200 = 9.8   8500 = 9.0     

Left to right bottom

8500 = 9.3    3135 = 10    CO711 = 10.8   7750 = 12.0    2892 =  10.7

All Right Handed. Left as well if you use brass washers filed out to the same size. insert, then reverse

I purchased some brass washers and have spent some time filing out the innards to fit the outer size of each of the Chinese winders. I now have the facility to place 10 different size springs left or right. It would have been too long to wait whilst I purchased springs of each size. Total cost £6.69p.

I see mention of the Bergeon #5, 6 and 7 being common mainspring winder sizes.  Does this budget 10 piece set cover those sizes?

I don't follow you on the brass washers.  Do you have a photo?

Here you go.

On the box above the holders are the washers I purchased. I filed them out to fit each individual wider and have inserted them on the winder.

I like the cheat sheet.

You've still got me puzzled on the washers.  How do those let you do left handed?

    • The epilame under the oil will also be removed 
    • If we use the rub-off epilame method of pallet stones (run dry for a few minutes before applying the epilame) where will the oil go/be transported when it is pushed away from the impulse surface by the escape wheel teeth? Onto the epilame-treated sections of the pallet! Once the oil has been applied/transported to the epilame-treated sections of the pallet where will it then go? Nowhere as the oil will remain on the epilame. So, perhaps the run-dry method defeats its intended purpose leaving the pallet impulse surfaces dry!? If, on the other hand, we do not remove the epilame from the pallet stones where the escape wheel teeth come in contact with them I'd expect more oil to remain where we want it and need it. Yes, I agree, that is the question, and my gut feeling tells me that is exactly the case. Epilame was created to have an adhesive trait and the oleophobic property is just a side effect.  
    • Might that be the viscous nature of oil resisting gravity H  ,  we have been comparing water and hydrophobic surfaces which are similar in principle but water is much less viscous than oil. I guess what we trying to discover is if epilame also has an adhesive trait as well as being oleophobic. Plus the oil dropet has very little mass for gravity to work on, like watching tiny water beads that can grip onto vertical glass until they are connected together to increase their mass then run down. Gravity isn't the only factor at play when oil is placed on pallet stones. The oil receives a lot of bashing that may push it out of position ? Thinking about it if the oil stays in position for 10 minutes enough time for the escape wheel to scrape off the epilame , then  a walled in lubrication has been achieved,  the epilame is no longer beneath the oil ( possibly mixed into the oil )
    • But it also makes it seem less susceptible to gravity. If you place a droplet of oil on an epilame-treated surface the droplet of oil will still stay in place even if you then flip the surface from a horizontal to a vertical position. That is, the oil droplet remains anchored, and that's the purpose of epilame. If it was just a matter of creating an oleophobic surface we could probably use other, less expensive, methods!? I don't know @Waggy but my gut feeling tells me you're spot on (pun intended!). I believe the oleophobic property is a side effect of epilame which is designed to keep the oil anchored.
    • Saturday morning 27/4 Sunday evening 28/4 Monday evening 29/4 Floor has a drain in the middle so I am hoping that there is very little fall on it, if any. Room is about 2.5 x 2.5 metres square. Can only use about 1/2 of one wall on the right of the pictures which has a sliding glass door in it. And only about 3/4 of the wall to the left of the pictures as it has the door to the house in it. Progress. 🙂
