Seiko Chronograph wristwatch, steel, SSB419P1
Stainless Steel Seiko Chronograph Watch with Black Dial, Tachymeter Scale and Yellow-Green Seconds Hand
The yellow-green chronograph seconds hand on the black dial sets this Seiko Chronograph watch apart from other silver-gray steel watches. The dial has three small subdials for timing and a date display, and a tachymeter scale runs around the edge. The indices and hands are luminous, so the time is visible even in dim light. In 1969, Seiko launched the Quartz Astron, the world's first mass-produced quartz watch.
The round case and bracelet are stainless steel. The case is 40 mm wide and 12 mm thick, and the dial is protected by a sapphire crystal. The quartz movement runs on a battery. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. The bracelet fits a wrist circumference of 160–210 mm.
