This is a vintage Hamilton "Martin" wristwatch, produced around 1941. It features a 10K gold-filled square or tonneau-shaped case with distinct rounded lugs. The watch is powered by a manual-wind Hamilton caliber 987A movement with 17 jewels. The dial is typically sterling silver with 18K gold applied numerals. It is considered a highly collectible Art Deco timepiece, with only 6,111 pieces originally made in 1941. Watch works and keep time, but its highly recommended to be serviced as i don't know when was last serviced, that way can go for another 80 years 😉 The leather band is in good condition! The watch will be selled As-Is. Please review my photos and video as they are part of description Thanks
