This is a very sharing, knowledgeable community so I would like to give something back and encourage others to possibly, do likewise. I've recently replaced the original 7S26a movement in my very early Seiko SKX007 diver with a 7S36a. There is nothing likely wrong with the old movement other than needing a thorough cleaning, oiling and regulating. My original diagnosis of a broken mainspring was in error. It is complete with day and date wheels. The original stem and crown are also included. It's absolutely free to anyone who wants it for a movement on which to practice your repair skills. I'll pay for postage anywhere in the world. The catch? You must do something similar with an item that you no longer need. It has to be watch or clock related, shipped at your expense and at no cost to the recipient. The first PM to me will be the new owner. Anyone?

    • First of all, thank you for the pdf file of the book on how to replace a gem. So, if there is a problem with the ruby in the movement, should I buy a new or used movement and replace it? When I watch videos on YouTube of people fixing used watches, I feel like there should be a way to buy a gem. Is there no way to buy it?
    • I suppose @donutdan is not forced to earn his living by repairing watches.  I suppose he does it as a hobby and wants to gain experience, to get better in watchmaking and time is not the issue. Then @donutdan should rather try to repair the damage instead of swap parts from a maybe intact other movement. Swapping parts is not watchmaking. And often swapped parts are not the expected solution of all problems. All mentioned damages are repairable. Frank  
    • Yeah I figured that one out when I googled and realized that my spindle is actually from Horia. It's smooth with no screwable cap.
    • I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.
    • Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break.
