Hello all,

I'm in need of a clutch wheel for my Gruen 877s Techni-Quadron Doctor Watch. There's teeth missing on mine. I took some screen shots of my watch for reference.

Thanks everyone!

This has been in my coa cue for some time, but it’s too nice to be collecting dust on my shelf. I’m considering listing it, so I thought I’d ask first if anyone would be interested. It is a later run, 2.27mm Gruen gf case, circa 1934 I'm guessing. It has a “Guild Watch” cal 485, which looks pristine. Original Sturdy bracelet. Winds sets and runs. (Update to timekeeping) lost 1.5mins in 24 hrs, but no idea of last service. If desired, I can share more pics in model database.
