The Seiko Prospex celebrates Seiko's 145th anniversary with a modern interpretation of the iconic 1965 Heritage Diver. Its 40 mm stainless steel case preserves the classic proportions of the original design while delivering contemporary performance. The silver-white dial is paired with a blue bezel inspired by the legendary Seiko Blue, a signature colour of the brand since the 1960s. A curved sapphire crystal with anti-reflective coating provides excellent clarity, while LumiBrite on the hands, indexes and bezel ensures optimal readability in low-light conditions. Powering the watch is the reliable Calibre 6R55, offering automatic and manual winding, hacking seconds and an impressive 72-hour power reserve. Additional features include a unidirectional rotating bezel, screw-down crown, screw case back and 300 metres of water resistance.
