It looks to be one of A. Schilds 340 series of ebauche movements. Sometimes there's no markings on these movements, go through Ranfit A. Schilds and ye should find

I think you are correct! close.  Those three-digit AS movements have a separate plate for the escape wheel.  Very similar otherwise.

Always good to bring one back to life! How did you tweak the balance pivot? Also, what did that come in?

I put it on a balance poiser and rolled it to find out which way it was bent.  It was not a really bad bend...just bad enough.  Then I noted the position of the roller jewel so that I could know when I was 180 degrees out of phase with the bend (the upward bend became a downward bend).  Then in that position, I gently pressed down to correct it while holding the balance with my other finger.  Once I thought I had made some progress, I took a triangular arkansas stone and rolled it along on the poiser on that pivot.  It was crude and the stone was larger than I wanted, but I could not find a better solution in the bench.  At the time, I did not know I had an equivalent Dumont #8.

Installed the hairspring (180 degrees out of phase!!!!) and installed only to realize my mistake.  Removed the hairspring and did it again right...close to right.  After installing the balance, I could see I was still out of beat.  So I removed it, put it on an anvil block, lifted the bridge while holding the balance and tweaked the hairspring collet.  Installed again and voila.

Lots of places along the way, I really need to channel either my dad or one of the experts on this forum, but I made it through.

Like I said...this is a "learner" watch, so there was no down side to the exercise.  I get incrementally better each time I work on one of these things.

The watch is still running in static position on the bench.

      School Me Please: Sliding Mainspring Bridles

      By caseback · Posted

      This is the old/first(?) way for making a mainspring for an automatic. "Evolution-wise" it is an logical first step forward from a standard spring. Usually these are indeed replaced with a new spring with an integrated/fixed bridle. Lubrication as you would do with any automatic.

      Unknown watch movement logo. Very interesting

      Thank you. I was informed it was a cheap worthless Lack watch from India. It’s in a small mens watch looks to be around 1930 odd   Cleaned the movement and it’s going really well. Keeps good time.  This is a great site. Mystery solved. I’m obliged.

      School Me Please: Sliding Mainspring Bridles

      By RickTock · Posted

      I'm working on a Schild AS 1250 (a 'bumper' automatic) and it's the first time I've seen a mainspring like this. It has what looks like a regular manual-wind mainspring with a 'hook' at its outer extremity. On a manual-wind watch that 'hook' would engage with a 'hook' in the barrel wall to prevent it from rotating. However, the AS 1250's mainspring does not engage directly with the barrel but rather with a 'sliding bridle' that sits between the mainspring and the barrel wall, and evidently facilitates the slip necessary in an automatic. I'm not sure what advantage this two-piece configuration provides, but it highlights a gap (one of many) in my horological knowledge. I'm not sure if 'hook' is the correct term as used above, but please see photo below to see what I mean. Therefore, two questions please. 1. What is the proper way to lubricate a barrel from an automatic watch with a sliding bridle? My guess is the same as any automatic ms/barrel (e.g, a few dabs of braking grease on the interior barrel wall). What do the experts say? 2. I purchased a Generale Ressorts GR3472X mainspring, made for the AS 1250. It looks like the bridle is included and I don't need to salvage and re-use the old one. Is this a safe assumption? Thanks for the advice. If you have any other wisdom you'd like to share about separate sliding mainspring bridles, I would be very interested. Cheers!
