In the late 1970s, Seiko produced the 6309 series, a timepiece that cemented its legendary status through its durability and engineering. Inspired by professional diver's watches, this movement was known for years as the "watch that never stops working." The Seiko 6309-552A, presented today, reinterprets this robust spirit with a modern aesthetic. This special piece adds a bold and contemporary touch to classic Seiko design with its emerald green aftermarket dial. The green dial, whose tone changes depending on the light, evokes deep seas and forest shadows, giving the watch both a sporty and collectible character. This dial color is one of the strongest details that sets it apart from ordinary vintage Seikos. Inside, Seiko's legendary 6309 automatic movement, with its battery-free design and renowned robustness, is still perfectly suited for daily use. This movement is considered one of the most successful examples of Seiko's "tool watch" philosophy.
