Seiko Chronograph watch, steel, SSB455P1
Stainless steel Seiko Chronograph wristwatch with three subdials and date display
Three black subdials make this Seiko chronograph a clear, sporty wristwatch. The chronograph can be used to time a sports activity, for example, and the date display sits between four and five o'clock. The round steel case is 40 mm wide and 12 mm thick, and its surface is brushed. The hands and indexes are luminous. In 1969, Seiko introduced the Quartz Astron, the first mass-produced quartz wristwatch.
The case and bracelet are stainless steel, and a sapphire crystal protects the dial. The quartz movement runs on a battery, with a stated battery life of about 3 years. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. The bracelet fits wrist circumferences of 150–210 mm, and the lug width is 20 mm.
