Breezing through a quick cleaning of the Omega cal 212 (ladies watch from the 210 series). I get to the keyless works and the yoke spring is below the yoke, not the more common set up. When the yoke is placed over the spring the only access to to the spring is through an opening on the opposite side.

 

I've tried coaxing the spring from the opposite side over a slightly loose yoke- Doesn't work as there isn't enough play even with a loose yoke.

I've tried removing the detente (setting lever), winding and sliding pinion (clutch) and I can get it in and cover with the setting lever spring to hold it but then I can't get the setting lever back in. The setting lever and winding pinion had to be removed so the yoke could slide high enough to have the stud catch the spring.

 

I'm hoping at least one of you has encountered this setup and figured out a rational approach.

Thanks!

I will hunt down one of these movements later and let you know what to do.

      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!
