Seiko Chronograph watch, steel, SSB425P1
Steel Seiko Chronograph watch with a silver-coloured dial, black subdials and a date display
The silver-coloured dial has two black subdials and a third, light-coloured one at the bottom, which makes this Seiko Chronograph watch graphically clear. The bezel has a tachymeter scale, and the date display is at the lower right. The round case is 41.5 mm wide and 12 mm thick, and both the case and the bracelet are made of stainless steel. A mineral crystal protects the dial.
The chronograph's 8T63 quartz movement runs on a battery. In 1969, Seiko introduced the Quartz Astron, the world's first mass-produced quartz watch. 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 145–205 mm. The watch has no luminous details.
