Seiko Conceptual Series Rotocall wristwatch, steel, SMGG21P1
Seiko Conceptual Series Rotocall Is a Stainless Steel Digital Watch with a Rotating Function Bezel and 100 m Water Resistance
What sets the Rotocall apart from other digital watches is the rotating bezel used to select the watch's eight functions: time, time setting, timer, counter, stopwatch, dual time, and daily and single alarms. It is modeled on a Seiko digital watch from the 1980s, which NASA astronauts also wore. The angular steel case is 37 mm wide and 10.6 mm thick, and the blue and gray bezel gives the silver-coloured watch a retro look.
The battery-powered A824 quartz movement has an LED backlight, and a Hardlex crystal protects the display. The steel bracelet has a three-fold clasp that opens with a push button. Water resistance of 100 m / 10 atm is enough for swimming and water sports, but not for scuba diving. In 1969, Seiko launched the Quartz Astron, the first mass-produced quartz wristwatch.
