14kt solid white gold case, style OS67, 37x22mm, back engraved "Presented to Mrs. Elizabeth C. Chapman by Teachers of PL12R Jan. 31, 1930." Excellent case with very little wear. Excellent original metal dial with light toning. 15 Jewel caliber 157 movement winds and sets properly. Watch runs to within 2 min/day or better, but not known when last serviced. 14mm wide black leather strap. Closest I can date this is year 1927 based on the "O" in the case style number. This predates the more familiar "XXX/XXX" case style found on later Quadrons. Interesting Quadron because it is a man's watch, but was presented to a woman, unusual for its time.
