The story
The Seiko 6309 is a notable automatic dive watch produced from the late 1970s to the early 1980s. Renowned for its robust design and reliability, the 6309 has gained a dedicated following among watch enthusiasts and collectors.
The watch features a distinctive cushion-shaped case, typically measuring 42mm in diameter, which provides a rugged aesthetic suitable for underwater activities. Its water resistance of up to 200 meters made it a practical choice for divers.
Powered by the Seiko Caliber 6309 movement, this watch is known for its durability and precision. The movement is a 17-jewel automatic mechanism that offers a power reserve of approximately 40 hours. The dial is characterized by its bold hour markers and hands, often coated with luminous material for visibility in low-light conditions.
Throughout its production, the Seiko 6309 was available in various configurations, including different bezel styles and dial colors, contributing to its appeal among collectors. The model is often regarded as a precursor to the more modern Seiko Prospex line.
This 6309 had clearly been well used. The all-black dial and bezel were reminiscent of the Willard 6105 divers produced during the 1970s.
The initial plan was to homage 1970s japanese graphic design and keep consistent with the black and white color scheme, but actually this piece is from 1983, which requires a slightly more updated and colorful aesthetic. Miam Vice, the ultra 1980s iconic TV show was the inspiration for the color scheme, with a shark chosen for the dial emblem because of it's almost cliched energy and confidence. The final design decision was to change the color of the steel to allow for more of a complete piece, and in this case a coffee/gold color helps to really set off the brightly colored strap, creating an eyectaching neowave final result.
