Vintage Hamilton Screws

[NST]

Hello people, I am currently collecting parts to repair a vintage hamilton watch its an estoril model and the problem is the screws that hold the movement on the movement spacer ring have broken and I am not sure where to find replacements. From what I know the movement is a hamilton caliber 60 movement also known as 688 in the watches that where sold in the United States. If any of you can help that would be much appreciated.

If it helps I'm pretty sure that you will see such screws on other movements/brands as well.

That is the screws that holds movement in the case. You could take two similar screws from an other movement. That 688 was made by ETA so you think a screw from a ETA would work. Looks about the same as  ETA 1080 .

Well I have a scrap 7s26 I use for practice and it seems the pallet bridge screws work well... so far

rogart63 It's basically an eta 2390 slightly modified

Seiko screws aren't the prettiest screws but they work. Seiko 7s26 has 0,70 mm size screws. ETA 2824 case screws should work.

Is there a good way to shorten the threads of a screw?

Tricky. I use a special holder. Not sure what they are called. Maybe someone knows. Put the screw in and file it to right length. Have som different ones with different holes. This are old watchmaker tools.

They are called lantern chuck tool. Horotec has one.
