Seiko Chronograph watch, steel, black, SSB417P1
Black Seiko Chronograph Watch with Tachymeter Bezel, Sapphire Crystal and Nylon Strap
The black dial, black steel case and black nylon strap give this Seiko chronograph a dark look, with white indexes and hands that stand out clearly. The dial has three subdials, and the bezel has a tachymeter scale. In addition to timing, the watch has a date display and luminous markings.
The round case is 43 mm wide and 12 mm thick, and a sapphire crystal protects the dial. The movement is the battery-powered 8T63 quartz movement. The nylon strap is 20 mm wide and fits a wrist circumference of 150–210 mm. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. Seiko launched the first mass-produced quartz watch, the Quartz Astron, in 1969.
