Managed to break this a few days ago and I've done some searching and I can't find a replacement.

First of all I'm not sure what is the name of this. Is it the third wheel ? It's from an Eterna 1034H bumper movement (lady caliber). I've found the parts list scan but it's of low resolution and I can't figure out which part it is. (possibly 220) It seems to be common to a few other Eterna movements as well. (all these or almost all should use this part 835-834-833   1033-1034    1076-1077    1158-1159)

Also, do you guys thing that it would be possible to repair this by micro welding or something like that ? Can this be made on a lathe ? It's very thin. Between 0.2 and 0.3mm thickness.

Any advice on how to proceed ? There's a donor movement available on eBay but it's beyond my possibilities especially since I'm not in the US and the shipping is astronomical.

There's also the possibility that a similar part from other movements might fit but that would be pretty rare.

The amount have hassle it will be to make a new pinion will be far less stressful then getting a donor movement or part. I think anything can be repaired there really is no limits if you have the skill, but this is my opinion. I don’t know how readily available the parts are but i know this movement is the first and only bumper automatic for ladies watch according to ranfft. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Eterna_1034H so you may have to wait until you can find a cheaper donor because I don’t believe any other calibers will have the same wheel since this is the thinnest ever made by Eterna. i have few sitting in my bench waiting for the same situation.

      Unusual Seiko dial damage

      Believe the relume (not a fan) was done a long time after the damage.

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
