Seiko SRN017 Arctura Men's Kinetic Day Indicator Two Tone Bracelet Watch

The Seiko SRN017 Arctura Men's Kinetic Day Indicator Two Tone Watch is an analog quartz watch equipped with an Automatic Generating System, the unique technology developed by Seiko, which generates electrical energy to power the watch by utilizing the movement of the arm or wrist. Seiko Kinetic was the first quartz watch powered by human movement, a development so significant it led to the application for more than 50 patents. The process uses an oscillating weight that is rotated by the movement of your wrist: this movement is transformed into a magnetic charge, then into electricity, which is stored in a tiny capacitor or a rechargeable battery. A Power Reserve Indicator shows exactly how much energy you've created. Like mechanical and quartz, Kinetic is a platform. Over the past 20 years, Seiko has created on this platform a suite of Kinetic movements, each bringing unique features to the consumer. It was at the 1986 Basel Fair that SEIKO unveiled its first Kinetic prototype. Introduced under the trial name of 'AGM', it was the first watch in the world to convert kinetic movement into electrical energy. It was the first step in a development that, 20 years later, has made Kinetic synonymous with environmental friendliness, high performance and long-lasting convenience to a generation of users worldwide. From the launch in 1988 of the first commercially available watch (then under the new name AGS) until today, over eight million Kinetic watches have been sold (as of 2007). In 1998, Kinetic Auto Relay was released, extending the 'at-rest' operating period of the watch to a remarkable 4 years. 1999 saw the launch of the Ultimate Kinetic Chronograph, a masterpiece which fused the very best of SEIKO's mechanical and electronic watch making skills, and in 2003 another Kinetic Chronograph was launched. At Baselworld 2005, the Kinetic Perpetual made its first appearance, combining Kinetic convenience and longevity with a perpetual calendar, correct to the year 2100. In 2007, SEIKO's emotional technology Kinetic Direct Drive is introduced.
