Is there a supplier who sells an assortment of small watch movement screws.

I have looked at 10 or so suppliers, including Otto Frei, Cas-Ker, Esslingers, Jules Borel, CousinsUK and others. They all have screw assortments but none of small screws like you would use on bridges in watch movements.

Thank you very much!

I have looked as well. Very recently I bought a collection off ebay. Disappointed. I was gunning for American watch screws. For Swiss screws that I have needed, I made them because my screw plates can cut those threads.

Occasionally old swiss or American joblots crop up on ebay. The bridge and cock screws tend to be the larger ones in a watch movement with the crown and rachet having the largest heads. A general assortment from most suppliers should include some of those sizes.

Thank you oldhippy. I will set up a saved search on eBay to be notified every day.

I have bought cousinsuk screw assortment and there are some very small screws there. If you’re looking for a specific type of screw there are possibly more.specific screw selections available.

Thanks Tom. I did see a few assortments but most of them seemed to gravitate towards pocket watches, case screws and the like.

Thanks Neverehoughwatches. I was looking at one collection today but very few screws. I'll be on the daily hunt on eBay.

Cousins do sell assorted bridge screws : https://www.cousinsuk.com/category/screws-wristwatch-movement
 

I bought the mixed selection they sell. It contains a good mixture from very small to bridge screws. Some are new, some obviously removed from movements. They have save me many times.

They are all metric, so if there's no particular pitch callout they will be standard. You can find the pitches on Asco-Schurch (tap drill diameters for steel and brass as well).

Thank you nickelsilver! This looks like a great resource. Also, i bookmarked them on my suppliers list.

      Any tips to correct a sloppy error?

      By Geotex · Posted

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      Movement holder made with 3D printer

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.

      I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.

      Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
