Seiko Conceptual Series watch, steel, SUR612P1
Two-tone Seiko Conceptual Series watch with a round steel case, silver-coloured dial and Roman numerals
Roman numerals on a silver-coloured dial and a black cabochon stone set in the crown give this Seiko Conceptual Series watch a classic look. The round case is stainless steel and 29.6 mm wide. The satin-finished dial has a subtle vertical stripe pattern, the bezel and crown are gold-coloured, and the steel bracelet is two-tone.
The case is 6 mm thick, and the dial is protected by Hardlex crystal. The bracelet is 14 mm wide and fits a wrist circumference of 120–200 mm. The quartz movement is battery-powered. Water resistance of 50 m / 5 atm is sufficient for swimming and frequent contact with water, but not for free diving, snorkeling or scuba diving. The watch has no luminous coating. In 1969, Seiko launched the Quartz Astron, the world's first mass-produced quartz wristwatch.
