1965 Heritage Diver’s Watch. Designed for those who treat life as the ultimate adventure, the Seiko Prospex collection meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence with re-creations and re-interpretations of landmark achievements. Updated with more power, greater water resistance, enhanced legibility and a compact construction designed for maximum comfort, this rugged yet sleek timepiece reimagines Seiko’s 1965 first diver’s watch, the beginning of the company’s legacy of setting the standards in dive watch technology and design. Framed by a coordinating uni-directional rotating elapsed timing bezel, the rich black dial offers a date calendar between 4 and 5 o’clock allowing for LumiBrite coating on the hands and all 12 markers, improving symmetry and legibility.
