Jewel spring is a headache to install

These jewels and springs are unbelievably small and a challenge to service. I managed to do one with the circular spring, no issues, but this one below is not cooperating. It's located on one of the bridges. Do you have some advice on how to install the spring? There's a tiny indent where I think the spring base goes in. I tried running one spring end under the lip of the chatone but the other side is hard to wedge in place and I'm afraid I'll break it. The other one just like it I lost. It pinged away into the ether. Thanks.

Oh the fabulous duofix. Inventor of this style should be roasting in hell for all eternity along with that damn soviet 3 legged circle spring. Anyway I'd say holding it in place with pegwood is the easiest way to install and it also wont fly away. Sharpen it like a flat screwdriver head so u have space to work around it but enough surface to hold it fairly firmly

I also recommend oiling through the jewel hole.

I agree.

Yes. Put a thin sheet of transparent plastic film on top of it and work "through it". It'll make it a lot easier and you won't loose the spring. 

Start with one leg, then position the second leg at the widest part of the circle/chaton to slip it in. Then slide back the two legs to insert the head.

After a long delay, I finally got the shock springs reinserted! I taped down the small bridge that held the jewel to my steel riveting anvil so it wouldn't move around and that helped a lot. The spring on the main body was easy in comparison. I purchased 25 springs from H&W Perrin in Canada ($9 with shipping) and found a good fit for the one I lost. Alex has great videos, which helped me with the spring. This Westclox with a Seiko movement is fighting me every step of the way. I'm sure it was never serviced. Almost every screw was frozen and needed a good soaking. The transmission fluid/penetrating oil combo worked best. The good news is that everything is in great shape.

      Calendar work certina 25-651

      By tonydagee · Posted

      Hello all, just disassembling to service, but I can’t figure out the working of the calendar work…it’s not operational the jumper and spring are ok, but the operation of the driving wheel has me at a loss. I can’t see a cam to drive anything. Is something damaged or missing? Help please!

      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.
