That looks good Geo keep us posted to how it performs.

Will do Clockboy.

So far it's been run continually for two days, everything turning as it should, no heating up and very little noise. The only minor criticism is the grommet where the cable enters the casing is the wrong size. The case is too thick for the groove in the grommet. Appart from that, it's all OK. :)

Hi Geo,

 

Do you see after these few weeks any reason not to buy this winder?

As Horology is a hobby with me, I have only used it a few times and it's working just fine. For the little money that it cost, I'm well pleased with it. :)

theyre used for testing the watch automatic winding.

Every movement in its specification has info how much it should wind on the machine,depending on the rpm of the machine

The watch is put on the machine,after the time has passed you remove the watch from machine and leave it, it shoul work, at least as the movement stated power reserve.

P.s.sent from my s****y phone,so sorry for typing mistakes

:bow: Oh the power of knowledge! And I thought I knew everything about this tool! ....I didn't know about the table, on second thought I even didn't have a second look at it! Not a pretty label, I'm enlightened!

 

Cheers,

 

Bob

Just a word of caution.

 

I purchased one of these off the bay a few years ago and it was OK for about 8 hours of use - then two of the arms fell off with the watches on them. further investigation, I found the arms are connected to a plastic rack and pinion mechanism with circlips that failed.

 

This unit may be different to mine (which I threw in the bin).

 

In the unit's defence - I was using it to wind up rather large and heavy watches like Breitlings and Omegas.

 

:)

 

Also, be aware that it winds watches in one direction only. So you have to think about how you mount a watch that only winds in one direction (a Valjoux 7750 for example).

That was something I hadn't thought about when I bought it. I decided to put it to the test and see what was going on. Luckily I have one if these see through automatic watches, so I put it on the machine to check things out. What I found was, due to the myriad of contorsion the watch goes through, the rotor fell in both directions. It did have a slight bias for the weight to turn in a clockwise direction as viewed through the "front" of the watch. This was when the machine was rotating in a clockwise direction. Another thing at I discovered, the machine does not always run clockwise when switched on, sometimes it goes anti-clockwise. When thIs happens the watch was observed to have the same bias when winding as it did when the machine was running anti-clockwise.

As promised here's photo if the drive gears and circlip. It definitely isn't the best quality, but I checked all the clips for proper location and tightness, and all seemed OK. So far "for the money" I'm very happy with it. It's run for about forty eight hours so far without any problem, but if it does start falling appart I'll let you know.

I've had one that lasted 2 years but I did notice that the cable had gotten tangled with one of the arms which kind of knackered the gearing. I now have a 2nd one and have tidied the cable. Mistake learned.

I found that some of the arms unscrewed themselves. I used loctite on all of the threads and no issues since.

      Epilame / Fixodrop

      Yes, I was referring to the (jewelled) gear train with HP (most of the time, I use 1300, but when Rolex says 1000, I'll use 1000).

      I suppose it would depend upon what your lubricating with those? for instance what does the manufacturer say about those lubricants? I have a PDF from the manufacture and a rather peculiar statement found on the bottom of the chart. my suspicion is the reason the recommending would be without epilam the HP oils like the spread except when they're in Ruby jewel's with steel pivots. tableEN lubrication 2020.pdf

      Is this a 'hack' ?

      By oldhippy · Posted

      These types of hairsprings become weak with age and very fragile. Which I expect it is that giving you trouble, and that wheel is not the correct one, if it were not bent I don't think the movement would run as the teeth are not the correct height. The problem you have is price which depends on you. It can be repaired but is it worth it to you, because there is little value in the clock. A wheel can be made and hairspring replaced. Or hang on to it and keep looking on ebay which is your best bet for replacement parts or even a complete movement but it will be like finding a needle in a haystack.

      I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.
