Seiko wristwatch, steel, turquoise dial, SUR525P1
Stainless Steel Seiko Watch with Turquoise Dial, Sapphire Crystal and Date Display
The turquoise dial gives this Seiko watch its look: the dial surface has a sunray shine, and the silver-coloured bar indices stand out clearly against it. The round steel case is 40 mm wide and 8 mm thick, and the date display is at three o'clock. Under the sapphire crystal, the indices and hands are luminous.
The movement is quartz, and the watch runs on a battery. Water resistance of 100 m / 10 atm is enough for swimming, water sports, snorkeling and free diving, but not for scuba diving. The steel bracelet is 20 mm wide and fits a wrist circumference of 140–195 mm. In 1969, Seiko introduced the Quartz Astron, the world's first mass-produced quartz watch.
