My Father is giving me a family heirloom that my Great Grandfather gave him. He is giving it to me for funding my two son's college education...woot! He had it appraised several years back and it came out to somewhere around 50K...though he doubts that it will fetch "near that much" in today's market. Photos are below. I dare not crack the caseback open with my limited knowledge and tools, therefore I don't have pics of the movement. It includes the original display box with Bailey, Banks & Biddle insignia inside, a little pocket of soft material, a gold/platinum chain and gold knife. Here are the few details I know regarding the watch: 'BAILEY, BANKS & BIDDLE' on watch face and caseback. 'Switzerland' at the bottom of the watch face. At the top of the winder where the chain connector is...is has 'PPC' stamped on it (Patek Philippe Company?). On the back of the caseback is engraved 'To XXXX XXXXXXX A Veteran of Veterans Semper Fidelis 1896-1940 From Sun Oil Company'. Can anyone tell me more about this watch? Thanks!
