 +
 +**Kinetic** is the brand name for [[Seiko]]'s [[automatic quartz]] hybrid movement. Originally called **Automatic Generating System** (**AGS Quartz**), it was developed between [[1972]] and [[1987]], when it first appeared in public.
 +
 +===== History =====
 +Seiko claims that the roots of the Kinetic system lie in a [[1972]] project to power the then-nascent [[quartz watch]] movements using conventional [[automatic]] winding rotors. Their first quartz movements relied on a chemical battery, and the company experimented with [[solar]] cells as well. This same research project gave rise to the Seiko [[Spring Drive]] technology, introduced 10 years after AGS, in [[1997]].
 +
 +The first public view of Seiko AGS came in [[1987]]. The technology was complete enough to be shown in a prototype watch with "A.G.S." on the dial and a transparent caseback through which the rotor could be viewed. The original AGS system used a geared winding rotor that directly powered a dynamo at up to 100,000 rpm. This differed greatly from the technology used by [[Jean d'Eve]] in Switzerland, which relied on a Dutch patented system with a spring between the rotor and generator and steady 15,000 rpm charging. Like the Swiss system, Seiko used a capacitor ("Electricity Storage Unit") rather than a chemical battery to store the electrical charge.
 +
 +Seiko introduced the production AGS Quartz watch at the [[Basel Fair]] in [[1988]], the same event at which Jean d'Eve introduced their [[Jean d'Eve Samara|Samara]]. This initial model included the [[display caseback]] so the rotor could be viewed and was labeled "A.G.S." on the dial. Early Seiko AGS Quartz models included a [[power reserve indicator]] function A press of a button moved the seconds hand to 5, 10, 20, or 30 to indicate low power, 1 day, 2 days, or 3 days reserve. The company claimed that the movement would be fully charged after 10 hours of normal wear, with 3 days reserve power.
 +
 +In September [[1993]], Seiko launched the [[Seiko 5M|5M4x]] movement and "Kinetic" brand name. This second-generation movement debuted at the [[1994]] [[Basel Fair]] and featured improved power reserve of up to 7 days. A later update in [[1995]] further improved power reserve, now up to 14 days. By [[1996]], Seiko had added the slim [[Seiko 4M]] and compact [[Seiko 3M]] movements. The 4M measured just 2.7 mm thick, a remarkable size for a movement with a full-diameter winding rotor. The 3M and 5M both measure 4.3 mm thick. These new movements feature advanced coil geometry, with a tight honeycomb-style wrapping of 0.03 mm thick wire.
 +
 +In [[1997]], Seiko introduced the [[Seiko 1M]], which the company claimed was twice as efficient as the 5M and 70% smaller. This movement measures 20 mm diameter and 3.2 mm thick and boasts a three month power reserve. [[ETA]] had released their [[Autoquartz]] line the year before.
 +
 +In [[1998]], Seiko gave reporters a preview of the next wave of Kinetic movements. The most unusual was the so-called "Spring Drive Kinetic", which was a preview of the [[Spring Drive]] movement and would soon dispense with the Kinetic name. They also demonstrated a Kinetic chronograph movement. This would be produced by [[2001]] as the [[Seiko 7L]].
 +
 +The [[1999]] Kinetic Auto Relay boasted an amazing four years power reserve by stopping the hands when the watch isn't worn. After 72 hours with no movement, it sleeps, thus conserving 85% of the power. This was also the first Kinetic model to switch from a true capacitor to a Lithium Ion secondary battery, now called the Kinetic Electricity Storage Unit or ESU. All following Kinetic movements would use this battery rather than the traditional capacitor, and previous models would be retrofitted.
 +
 +The Kinetic line was again updated in [[2005]] with the launch of the first [[perpetual calendar]] version. This [[Seiko 7D]] movement also boasted the Auto Relay power conservation function and the Lithium Ion ESU.
 +
 +[[2007]] saw the launch of the Kinetic Direct Drive, which allowed [[hand winding]] and featured a [[power reserve indicator]] on the dial at 9 00. This [[Seiko 5D]] movement would become the flagship Kinetic movement as the [[Spring Drive]] took over the higher-end.
 +
 +The next major Kinetic release came in [[2014]] with the Kinetic GMT. This movement was used in the high-end [[Seiko Prospex]] line and boasted 1 second per day accuracy.
