I've got this 1963 Seiko 66. Not worked on one of these before. Can anyone advise how I get the movement out please?

I have removed the bezel and it started to run, probably because the bent second hand was stuck, which is promising.

It doesn't look like the back comes off but I'm not sure?  Does the crown and stem pull out or unscrew?

Any help appreciated.

If you haven't work on a 66 previously, remember when disassembling it that there's a tiny washer between the 4th wheel and the center wheel bridge. It can be easily forgotten and get lost in the ultrasonic or in the cleaning process.

      Broken barrel arbor.

      Thanks Ross, yes i remember the broken arbor screw you had to deal with. Dont give up, if i can drill a tiny hole in a bloody hard barrel arbor without breaking the drill bit then you'll get that screw out one day somehow .

      Identifying watch for possible radioactive concern

      By Geotex · Posted

      Isn't it most correct to say that the mixture of radium decay pathway compounds found in old lume will produce both alpha and beta particle radiation as well as gamma rays, so it's over-simplistic to dismiss it all as low-energy particle emission? True, a cheap geiger counter chirping away with a raw CPM count won't specifically give you the relevant biological dose, but it makes it easy to tell the difference between your local background, a watch with a bit of activity, and one that is comparatively quite active. Each person can make their own risk analysis based on their understanding and concern, but there's nothing wrong with using an inexpensive meter to help make the determination.

      PALLET FORK INSTALLATION

      By mbwatch · Posted

      A lesson I learned last month on a Junghans pocket watch where both pins were bent over like stalks of wheat in the wind. I bent them back straight, wondering what a shock the thing must have taken to somehow bend even the outside pin over. And then the escapement wouldn't unlock at all. Probably the pallet stones are too long but I'm not ready for that repair yet so I bent the pins back over and it runs 0/0.2

      Never. Brilliant work and photographs. Thank you. On my very first watch I knackered the arbour. I think the screw I put in was the crown screw. I didn't know about left handed screws then. Head sheared off. Thread broken just below surface. If I had the space, then a lathe would be my wished purchase. 2 1/2 years later and I still get the arbour out now and again and...... I can dream. It's a lovely pocket watch. Ah well.

      PALLET FORK INSTALLATION

      Hello Davis. This thread is interesting. Thought I'd add my twopenneth worth. A short while ago I had a similar problem to you. Not a broken banking pin, but I did alter a banking pin. Much to the consternation of members. Rightly so. However I did as they suggested and obtained a complete donor movement and installed it into the watch. The client, who I did not charge but did the work as a project for myself, was as happy as Larry.  Can you not look for watch of the same name? A Donor watch or movement.  Keep us posted on your result please.
