Serviced July 2019, excellent original silver dial with 18k gold applied hour marker dots and flush gold markers, polished 10k gold filled case, stainless steel screw down case back. Lightly worn brown genuine leather strap, alloy mainspring, high domed NOS acrylic crystal.Made from 1955 through 1957, the Automatic K-454 became to be known commonly as the Sputnik. The K-454's unique dial with applied gold dots and flush gold markers that align with the lugs is reminiscent of the Soviet satellite that was launched in 1957 that it takes its nick name from. Unlike the Soviet Sputnik that orbited the earth, this Sputnik features a Swiss made 661 caliber automatic movement with 17 jewels. The original silver dial has very light patina, most noticeable near the 12:30, 2:30, and 4:30 positions. The painted Hamilton logo and the automatic and Swiss branding are excellent. The applied hour markers are 18k gold. The hands appear to be original and are in good condition with light patina. All but a small section of the lume is gone. There is no plate wear evident on the one piece 10k yellow gold filled case, but there is one small ding on the edge, near 9:30. The watch comes ready to wear on a vintage style, gently worn genuine leather two piece strap with gold tone buckle.
