Gruen Authority

Classified “Extra Precision” in my 1926 parts catalogue, although not stamped with the diamond. Have yet to encounter the top-winding 841, which I presume is in necklace models. Showing a bridge side pic from my original copy of 26 parts catalogue.

Dims: 5.5 x 10 ligne
Dial mounts: 2 dial side screws
Front plate marks: sn & “A 32”
Dial maker: unsigned (illegible stamp, possible import or American Art Enamelers)
Dial markings: no “Switzerland”; has 2 serial #s etched in back: “179928” (matches movement) & “1023408”
