Automatic quartz
[citation needed] Japanese company Seiko pioneered the technique which it unveiled at the Baselworld 1986 trade show under the trial name AGM.
[3] The watches had an average monthly rate of ±15 sec and provided 75 hours of continuous operation when fully powered.
They were part of the premium Flatline series of movements[6] and were sold to a variety of watch vendors, primarily European and American.
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).
[citation needed] Movement calibers:[citation needed] 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.
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.
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.
ETA sold Autoquartz to a variety of Swiss manufacturers with pricing below $100 (Swatch) to multiple thousands (Omega, Baume et Mercier, et al.).
