Unknown Pocket Watch Movement - Escape Pivot Broken - Would really appreciate your thoughts on options...

Hi Everyone,

I've included some pictures, below, to help possible identification but failing that, I'm working on the basis that my only option is to find a replacement escape wheel arbour of the correct length and re-fit the pinion and wheel [friction fit] back onto it.  I removed the arbour from the wheel using a suitable stake.  I've searched a fair bit and can't find arbours for sale individually.  I'd appreciate any guidance on this one - and if anyone recognises the movement, it might help me to source a replacement wheel.  Thanks.

Do you know if the pinion is all one with the staff?  If the pinion is pressed onto the staff, then you can use the old staff as a pattern to turn a new one if you have a lathe.  
If you have a pivoting tool instead, but no lathe, then Cyclops is right - repivoting may be easier than tracking down a donor of the exact size.

The pinion is one whole thing, no separate staff, no such things in watches. Yes, repivoting is the solution, no mater if it is done on lathe or by drilling tool.

The other way is to replace the pinion. Then, longer one with same outside diam and leaf count will be needed and it must be turned on lathe to the needed lenth/shape and pivots formed. The table of the wheel has to be riveted on the pinion, at least the pinion on the picture is this type, but strangely, it seems that it has not been riveted.

One of the problems with obtaining spare parts of course is identifying of the watch. But even if we could identify the watch it would assume that there were spare parts available. Often times there basically were never any spare parts available even if you could identify the watch.

Yes the unfortunate reality of watch repair is sometimes you're just not going to Be able to fine spare parts that means you're going to have to repair whatever you have.

Thanks everyone.  As a result of this dicussion, I've decided to jump into the world of lathes and pivoting tools but before I dive in, I have a few questions, which I'll raise under a separate, lathe/pivot-tool specific post.

      Hour hand won’t go past certain spot when adjusting time forwards

      If the watch is new, just return it to the seller for a refund or replacement.

      Keevo, Welcome to the group ! I'm thinking that you have some damage to the hour, and/ or minute wheel. Possibly just a bent, otherwise damaged, or missing tooth.   Your photo didn't post that I can see. I think you'll have to open it to start really finding the issue. Best, Randy

      Cap jewel with what looks like a circular engraving around the edge

      By mikepilk · Posted

      In cap jewels on several watches I have serviced over the years. I've recently serviced a couple of Longines movements where the cap jewels were colourless. They are a real pain. Without colour they disappear when immersed in any liquid for cleaning 😲 Not necessarily. Cousins do a 10ml bottle for £26 which will last me for years. That's just half the price of a simple Bergeon silicone cushion, so not too expensive 🤣

      Etachron regulation system

      By BobG · Posted

      I wanted to post an update as I have two movements running really well now, 230-250 amplitude , 0.5 and under beat error, and +/-8 seconds or so. I removed the hairspring assembly in order to start over and noticed that the terminal curve between the stud and regulator arm was distorted. The stud was lower than it should be. I massaged the curve to look pretty good and reinstalled it. I followed Alex's video advice, best I could with 10x magnification, and with the regulator arm set in the middle of the curve I adjusted the stud so the spring was centered. I then made sure I could move the regulator arm the entire terminal curve without upsetting the coils. I then put it back on the Timegrapher and began closing down the regulator pins until I saw a change in amplitude which means to me that the pins were now pinching the spring. I opened them slightly and it looks good except I have a 0 on dial down, +3 on dial up but -16 on crown down.  I'm a bit stuck on how to adjust out the positional error. I also noticed a drop in amplitude, 180-200 on crown down. In the other video link I posted at about minute 26 if I remember he adjusts out positional error by manipulating  the regulator pin gap. With crown down the hairspring falls away from the pin and the rate slows so he closes the pins a bit to keep them tighter in crown down position. That means the spring is tighter on dial up as well but then he moved the regulator arm to slow the movement.  There must be some Seiko experts here that have some methods for dialing out positional errors.
