Any possibility of a clearer image or some details of what's marked on them? Looks like mainspring both but I'm imagining what it's like to have cataracts and -9 diopter vision at the same time.

I've something very similar somewhere, came as part of a lot one at auction a few years back.

One could be used to measure the spring thickness while the other would be used to measure the spring height.

Ok thanks guys, I take it the one with the split down the middle is used to measure spring thickness by sliding said spring down the split until it stops, and the corresponding lowest line/mark is the thickness measurement to be read?

And the other tweezer like tool you just lay the spring in a slot and the one that it fits gives you the height?

i must say a vernier gauge does the same job, along with a micrometer.

That's the idea with the thickness and yes you're right that a micrometer would do the same.

I didn't notice that the other tool was tweezer like so it may be that it's a watch hand holding tool rather than as my first thought to measure spring height. See link below for one currenty on sale to allow you to compare and decide for yourself.

You are correct with that one.

      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.
