The original automatic 1965 Diver's watch symbolized Seiko's commitment to crafting timepieces that met the rigorous demands of diving, prioritizing reliability, safety, and professional standards. Notably, from 1966 to 1969, members of the Japanese Antarctic Research Expedition trusted this watch during their journeys to the South Pole, highlighting its resilience in harsh conditions.

It features a three-fold clasp with a secure lock and push-button release mechanism, along with an extender for added convenience. The case size measures 40.0 mm, ensuring a comfortable fit on the wrist. Other notable features include a screw case back and a screw-down crown, enhancing the watch's water resistance up to 300 meters.
