Picked this up for $5 at a yard sale. Brought it to the jeweler to get the battery replaced. In a hurry I didn’t realize it wasn’t ticking until I got home. (Thanks for nothing jeweler). 


Anyways now I feel a bit determined to get it running but have no experience in this. Took the back off and can see the coil doesn’t look perfect. From googling this seems to maybe be the issue? Also the battery doesn’t really stay “seated” it flys out unless held in place. 

Anyone know what model this is? Anywhere to order a coil from? Worth it as a little project for a $5 find?

Someone has been a little rough and clumsy with the coil hopefully not your jeweler. You could test it for continuity but i think that its pretty much a given that it is damged. Not particulary difficult to change when they are seperate to the circuit board, just be very careful to avoid handling by the copper coils. Sometimes they are paint  or varnish  protected to toughen them up for handling,  this one looks like raw copper. The battery is held  in place by the tab as indicated, not a great design but fairly standard for Jap. Movements.  The battery can flip out, be sure it is seated effectively under the tab. Look out for any leaked battery residue as this will eventually corrode the circuit board. Happy repairing 👍

Hi The coil looks a bit suspect, parts can be had from Jules Borel  USA. I have checked and the coil is available  at $11.70 on their site.  But first check the battery is ok  as I have known some not work and If Jeweler's change battery's and if the watch does not start they give up as they have no means of testing the watch,  Check out Borel's 

Attached the tech sheet for you.

depending upon what you paid take it back to the jewelry store and say it doesn't work.

This is why it's better to go to someplace specializes in batteries the good places will usually give you some kind of a warranty in other words the money you already paid will go to a repair. Good places will usually tell you whether the watch works are not. The problem is anybody can change a battery and it's a fast way to make money but not necessarily good for the customer.

Any luck with getting this one sorted?

      Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!

      Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor.

      I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂

      Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
