I've never seen screw heads with anything other than slotted screws in Swiss watch movements, although Philips head screws are used in watchcases and Seiko. Maybe this will help?

What is the spacing of the holes Dan?

I don't know where you'll find the "right" tool, but there are a number of options...

Searching for TH3 security screwdriver will get you 3.35mm between the outer edges of the holes. TH4 is 4.45

You could try a pair of mini circlip pliers, or a pair of dividers.

You could make your own - take a sort strip of steel, bend over one end and file a slot then round the edges to make 2 pins. Or if you wanted to take the crude approach, 2 tapered clock pins cut to fit snugly in each hole and a pair of pliers.

Hi stuart

about 2.5mm to the centre of the holes, I agree with you, making something may be the answer

thank you for your answer

most appreciated

I'm in the same boat, Off to B&Q tomorrow for 0.7mm drill bits, A great bit of advice/ work around.

Since then I have also made / converted a set of needle nose jewellers pliers 

I can not remember the movement - sorry

This might well work as mentioned by mickey871 above. It isn't all that expensive either.

It is similar - certainly appears to have a design influence

As StuartBaker104 pointed out a similar thread seems to be going on at two places.
I usually use tweezers to unwind the two hole nut in these movements, but for those who isn't comfortable to do so I just tried out another solution. 
Since these nuts appear in movements of different ligne, the distance between the holes will differ. It probably will do between manufacturers too.
The simple solution is to buy a small divider and modify the tips, make the tips flat instead of pointy. This will make them less likely to slipp. Now you have a tool like "one size fits all".

... now why didn't I think of that. By far and away the best suggestion.  Give that man a medal at once. :D

Excellent - the dividers was one of my suggestions above, but pleased to see it works in practice :-).  I'm sure I have some of those somewhere, so I know where I'll be keeping them when I track them down.

      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!

      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.
