1955 Hamilton Automatic K-454 "Sputnik"

1955 Hamilton Automatic K-454 "Sputnik"

Serviced July 2022, 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. Leather and gold plated expansion bracelet, alloy mainspring, NOS high domed acrylic crystal.

Made from 1955 through 1957, the Automatic K-454 is commonly referred to 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 Sputnik that orbited the earth, this Sputnik features a Swiss made 661 caliber automatic movement with 17 jewels. The original silver dial has light patina visible. 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. The hour markers and hands have been relumed. There is some brassing evident on the case on either side of the crown as well as between the lugs. The watch comes ready to wear on a vintage gold plated expansion bracelet with leather accents. The 661 automatic wind movement was serviced July 2022 and is running well and currently performing at +/- 13 seconds per day.
