Automatic quartz

Japanese company Seiko pioneered the technique which it unveiled at the Baselworld 1986 trade show under the trial name AGM.[2] The first such watch was released in Germany in January 1988 and April of the same year in Japan (under the name Auto-Quartz).[3] The watches had an average monthly rate of ±15 sec and provided 75 hours of continuous operation when fully powered. Early automatic quartz movements were called AGS (Automatic Generating System).

In 1991 the company introduced the Kinetic brand name.[4]

Today Seiko offers a wide range of watches with various Kinetic movements. The top of the line is the caliber 9T82, included in Sportura (international brand) and PROSPEX (only marketed in Japan) Collection. It is sold in limited volume at a price range of about US$3000 which makes it one of the most expensive automatic quartz watches. Kinetic technology has also been used in some of Seiko's Pulsar and Lorus watches. As of 2007, Seiko has sold more than eight million automatic quartz watches.[2]

The different calibres of Kinetic watches currently are relatively large and heavy, weighing in at 1/3 of a pound (150 grams) or more on many models. Therefore, most Seiko Kinetic watches are only available in a men's size.

Swiss company ETA SA, part of the Swatch group,[5] made seven different automatic quartz movements, calling them Autoquartz. They were part of the premium Flatline series of movements[6] and were sold to a variety of watch vendors, primarily European and American. High grade movements designed to last as long as their premium mechanical movements, they had between 15 and 53 jewels. Unlike most quartz watches, Autoquartz could be calibrated[7] to increase their accuracy. Several vendors had their Autoquartz watches COSC certified. In 2006 to increase production of its highly demanded mechanical movements, Swatch discontinued supplying the Autoquartz line to customers (service and parts are still available). Then in 2009, possibly due to available production capacity or stocked parts, Tissot reintroduced the Autoquartz in its PRC200 dive watch. The Autoquartz movement used by Tissot is gold plated and carries the designation ETA 205.914.

Movement calibers:

• 204.901 (small 8.75 lignes used primarily in women's watches)
• 204.911 (replacement for the 204.901 upgrading from a capacitor to a rechargeable battery)
• 205.111 (discontinued and replaced by the 205.911 which upgraded from a capacitor to a rechargeable battery)
• 205.711 (15 jeweled movement used only by Swatch Watch for a variety of its fashion watches)
• 205.911 (the most commonly available movement having 17 jewels and often ordered in gold plating)
• 205.914 (no information available from ETA)
• 205.961 (a 205.911 with the addition of a GMT hand)
• 206.211 (a 205.911 fitted with a Dubois Depraz 2021 to make a chronograph. With 53 jewels the most jeweled quartz movement ever made)

Manufacturers who employ or employed ETA movements: Tissot, Rado in their Accustar line of watches, Longines, Swatch, Omega (Omega Seamaster Omega-matic), Dugena (K-Tech), Wenger (GST Field Terragraph Autoquartz), Hermès (Nomade), Roberge (Altaïr), Mido (Multifort), Bovet (Autoquartz calibre 11BQ01), Fortis (Spacematic Eco), Belair (Autoquartz), Franck Muller (Transamerica), HTO (Grand Voyager) and Cyma.

Citizen, one of the world's largest watch manufacturers, also built an autoquartz-powered watch: the Eco-Drive Duo (released in December 1998).[8] Novel to this watch was the use of both mechanical power as well as a solar cell. This model was an attempt to enter higher-priced markets (at a cost of around $1000 USD), but the technology failed to attract consumer interest and Citizen has since stopped making use of the unique movement. No other autoquartz powered watch from Citizen is known; all other Eco-Drive models only use solar power or thermal power.

Ventura is a small Swiss watch manufacturer claiming to be "the World's only manufacturer of automatic digital watches". Their VEN_99 movement was the only watch to ever combine autoquartz and digital readout of time (LCD) in one package. Offered were three models: the Sparc rx, fx and px. In late 2006, the company started selling their movement with an incorporated alarm, another exclusive feature. All hardware is proprietary to Ventura.

In 2007 the company went into bankruptcy.[9] Support was available from an independent entity. In 2011 the company re-emerged from bankruptcy and continued to sell its models, introducing the "2nd gen Micro-Generating-System" and marketing the watch (Sparc MGS) integrating it as the world's first and only digital-readout multi-function automatic quartz module.[10] Unlike with other manufacturers the watch movement (VEN_10) and power source (MGS) are separate units, only linked by a single wire.
