    Seiko 66A, want to rescue...

    Hi all, and thanks in advance for any and all replies!

    Amongst a recent batch of vintage gear we got a Seiko 66A based watch; quite pretty and in good condition but has an issue where you can only wind it a little before it starts "skipping" like something is stripped (worn gears?).

    Any idea what it could be? And is it worth for someone who has never taken a movement apart to even attempt to fix it? I have removed and installed movements and done other minor things but never actually disassembled one. Or should I look for a complete movement from a watch that is in poor cosmetic shape unlike mine and then transplant that? If so, are there other compatible Seiko movements that will fit the same case/dial/hands should I not be able to source a 66A?

    thanks!

    As a rule, the very first five or ten movements you try to fix you ruin. So don't start on anything you want to keep.

    As to swaps you provide no pictures, measurements, or useful data beyond the movement calibre. While all of that data can be derived if one has detailed drawings of the movement, you can probably find that as easily as we can.

    There is an old seikos website out there somewhere. Maybe they have that data. Or maybe someone will come along who does have that data.

    Good luck!

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    Thanks! I did some searching and it looks like the 66B is the only candidate for a direct swap. Since it is already broken I will at least disassemble it and hopefully learn something from it, then see if I can pick up a better working 66A or 66B when I inevitably destroy it beyond salvation....
