Vintage Art Deco Watch Lot Of 5 Gruen Precision Quadron, Ollendorff, Olympic etc.

The Gruen Precision Quadron (early 1920’s) movement is complete save for the winding stem. Balance doesn’t rotate freely when blown with air. The center wheel pinion is snapped where it inserts in the cannon pinion. The dial is dented, and the base plate is also slightly dented in the same place. This watch sells for $800 in good condition.

The Ollendorff watch works for a while when the balance is blown with air, which is surprising given that the winding stem and crown are missing.

The rest are completely untested. The one with the yellow crystal is by a company called Olympic, and I believe it is 15 jewels. Assume they do not work at all.
