This timepiece represents a contemporary interpretation of Japan's and Seiko's inaugural Diver's watch, which debuted in 1965. The original automatic 1965 Diver's watch marked the onset of Seiko's endeavour towards crafting timepieces renowned for their diving reliability, safety, and professional-grade specifications. Notably, between 1966 and 1969, members of the Japanese Antarctic Research Expedition relied on this watch during their expeditions to the South Pole, underscoring its durability in demanding conditions.

Highlighted attributes of this watch include the Calibre 6R55 movement, ensuring precise timekeeping. It features a three-fold clasp with a secure lock and push-button release mechanism, complemented by an extender for enhanced functionality. With a case size measuring 40.0 mm, this watch promises a comfortable and stylish fit. Other notable features include a screw case back and a screw-down crown, which contribute to its impressive water resistance of up to 300 meters. Moreover, the inner surface of the glass is coated with an anti-reflective coating, optimizing visibility in various lighting conditions.
