Help Identifing a watch Citizen


Recommended Posts

I am trying to find information on this watch. on back of cast: Citizen 25 Jewels  4-760182TA BLG-K GN-1-S  and Japan imprinted on bridge. On the front Citizen Automatic.

This one was fixed in the past and the gentleman removed the second hand and the post that it runs on. I am wondering if he changed out the cannon pinion. If someone knows where I can find parts or and old movement I could strip down to replace what is missing that would be a big help.

Client said this came from an uncle that owned a watch repair shop in the 60's. He told him that this watch was a  Dealer example to show the customers how the watch worked. I would really like to find and replace the original second hand if I could.

Thanks, Charlie of OldManTique

That is a Citizen Skeleton . I had one of those . Dropped the clutch wheel when servicing it . I search almost everywhere for a replacement.  I ended up selling it as donor watch. 

Maybe it's easier to find one today? Think the movement is 7290 ?

    • Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.
    • That's a good idea - shrinking down the nut and wrench size from the old casebook trick!
    • I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.    
    • I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.
    • I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.
