Pristine or Museum Quality is the way to start with this GORGEOUS Waltham 16 size, 15 jewel, model 1908, Grade #620 that is ABSOLUTELY STUNNING!! It has a PERFECT single sunk porcelain dial with black Roman numerals, blue spade hour and straight minute whip hand, and is signed in script “Waltham U.S.A.”. It has a BEAUTIFUL ¾ nickel movement Model 1908 that is signed “15 Jewels, A.W.W. Co. Waltham, Mass.”. Now is time for the best part. It comes mounted in the most PRISTINE Keystone 14K Gold triple hinged case that I have ever seen. It is signed “Keystone 14K on the dust cover and GUARANTEED 14K .585 FINE, THE K.W.C. CO. 6117895” on the back cover. The front cover is beautifully engraved with a bird in flight and the back has a FANTASTIC home scene. This is definitely a MINT, NOS, case that should be called MUSEUM QUALITY!!! SN 22396776 Ca. 1918.
