Seiko Chronograph watch, steel, black dial, SSB430P1
Stainless Steel Seiko Chronograph Watch with Black Dial and Gold-Coloured Subdials
The black dial has two gold-coloured subdials, and the same shade is repeated in the indexes, bezel, crown and the center links of the bracelet. The round steel case is 41.5 mm wide and 12 mm thick, and the bezel has a tachymeter scale. The date window is at the lower right of the dial.
This men's watch has an 8T63 quartz movement, a timing function and mineral crystal. The steel bracelet fits wrist circumferences of 145–205 mm. Water resistance of 100 m / 10 atm is suitable for swimming, water sports and free diving, but not for scuba diving. The hands are not luminous. In 1969, Seiko launched the Quartz Astron, the world's first mass-produced quartz watch.
