Could someone tell me the smallest screw driver to the largest screw driver i need for pocket watches and wrist watches?

Thanks

Hey Douglas,

Welcome to the forum.In my experience, You'll need these 5 sizes to get anything done:

0.60 mm Pink

0.80mm Yellow

1.00mm Black

1.20 mm Red

2.00mm Green

There may be a few brands that use screws sizes on either end of the spectrum, but these will get you through 99% of wristwatches and most pocket watches.

What about the .00 and .5 ? I ordered a set today that had those in it up to 1.5mm. 

Thanks for the help. 

The 0.5mm will work in place of the .60mm and you'll see the difference when you use those sizes. I suggest you use the screwdriver that is closest to the slot size to prevent slipping. This happens anyway, but will be reduced if you use the proper size screwdriver. I remember I was tempted to use smaller screwdrivers on the larger barrel or winding wheel screws and simply messed up my small blades when they came up short on torque and slipped. Lesson learned!

The reason i bout them that small was because i want to restore my gransfather wrist watch at some point in the future....there was a screw so small i could barely see it. That being said, the set was the only set i have run across that had that small of sizes...figured i better grab while the grabbing was good...it was a swiss set of 7 for $12.no one bid on it but me and one other.

What type of watch is it? Can you post a picture or the caliber?

Its a beauty! We'll get that going...I'll help you in any way I can and so will the other fellows here. They're all top notch. Have you ever disassembled a watch before?

JC

No, just started learning and getting tools together...got a pocket watch movement on the way to start practicing on.

OK that's a good plan. You'll need good lighting (either regular bulb or fluorescent/LED type) and quality 10X loupe (Bausch and Lomb or something good quality) and a general magnification visor with 4X. You'll also need at least one movement holder and a mat to work on.  One more thing: a good set of tweezers! I got some from Ebay that are decent, but they must be Swiss because the quality is the best and you need good tweezers to work.

Gonna start marks videos as soon as I can..might be awhile though.

Perfect. That's just how I started and I've done many, many watches since then. Mark's videos are the best and his technique is superb.

That is a NICE balance tack...much nicer than a metal one.

      1972 Bulova President "E" Sea King 11ACACB movement

      By ManSkirtBrew · Posted

      Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!

      Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor.

      I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂

      Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
