Seiko Racing Sports Chronograph wristwatch, steel, SSB403P1
Steel Seiko Racing Sports Watch with Chronograph, Gray Dial and Striped Nylon Strap
The striped nylon strap gives this Seiko Racing Sports chronograph a sporty look: gray and orange stripes run over a black base, and the same orange appears on the center hand and the tachymeter text on the bezel. The gray dial has three small subdials and a date window, and the indexes and hands are luminous. The round steel case is silver-coloured, 41 mm wide and 12 mm thick, with a mineral crystal on top.
The quartz movement is battery-powered, and in addition to timing, the watch has a date display. Water resistance of 100 m / 10 atm is enough for swimming, water sports, snorkeling and free diving, but not for scuba diving. The strap is 22 mm wide and fits a wrist circumference of 175–240 mm. In 1969, Seiko launched the Quartz Astron, the first mass-produced quartz watch.
