Gruen ladies wrist watch, 17 jewels, unadjusted, marked on works cover with "Gruen Watch Co.", "Precision", "00532", "Switzerland." On cog is "VERITHIN PATENTED." Inside case back are the caliber and style numbers "463/210" and serial number 4557581. The case interior is further marked "Cased & Timed in U.S.A by the Gruen Watch Co. 10KT Gold Filled Bezel." The face is square with raised gilt letters with "GRUEN VERI-THIN" and "Switzerland." The case back is marked "Gruen Guildite Base Metal." It appears to have the original or period replacement band. The clasp is marked "PAT. No. 2133546." The watch is approximately 18 mm across. Condition issues: not in working order and priced accordingly. We have not had it restored and it will require a proper cleaning. As to age, it is difficult to date Gruen watches, but the numbers inside the case back indicate circa 1938-1940. I hope these details provide the information needed to further research this pretty little vintage timepiece.
