Citizen Eco-Drive METAL AW1365-19P featuring a light-absorbing 'solar ring' instead of solar cell panels, allowing opaque metal dials to be used. Eco-Drive is a model range of manufactured and marketed worldwide by, powered primarily. As of 2007, the company estimated the drive system had eliminated the disposal of 10 million batteries in North America. Citizen introduced the Eco-Drive line to Asia, Latin America, and Europe in 1995 and to the United States in April, 1996. The Eco-Drive concept introduced several technical refinements over previous solar powered watches, including light-capturing cells that could be made virtually invisible behind the dial instead of highly conspicuous, enhancing the appearance of the watch. Contents • • • • • • • • • • • • • • • History [ ] Eco-Drive concept [ ] The technical platform that made the Eco-Drive concept possible was the Eco-Drive caliber 7878 movement. This movement was the first light-powered movement where the could be mounted under the dial.
Previous light powered watches from Citizen and other manufacturers had the solar cell(s) mounted directly on the dial. This innovation was enabled by marked improvements in thin film solar cells, which, by the early 1990s had become significantly more. By locating a sufficiently translucent dial material over the now more efficient solar cells, enough light could pass through the dial face to power the movement. Though the Eco-Drive caliber 7878 movement solar cells remained slightly visible through the dial, the physical styling of the light-powered watch was no longer constrained by visible solar cells. To store electrical energy the first Eco-Drive movements employed.
This battery type became available in the early 1990s, enabling an Eco-Drive 7878 movement to run 180 days on secondary power before requiring recharging via light exposure – a marked improvement in energy storage over previous light-powered watches. The movement also featured an 'insufficient recharging' indicator. Commercial history [ ] In addition to the first three Eco-Drive models introduced in 1995, Citizen marketed numerous other Eco-Drive models during the 1990s, including the 6.05 (0.238 ) thick Eco-Drive Slim of 1996.
Where the first models offered hours, minutes, seconds and date features, ultimately the movements evolved to include a broad range of design features, including complex analog and digital-analog movements and the of, and. In the early 2000s, while wristwatch sales declined with the advent of cell phones and their timekeeping capability, demand for Citizen watches in North America remained robust. Eco-Drive models were well received, generating a third of Citizen's North American revenues by 2000. In 2002 the VITRO technology (Eco-Drive VITRO) came on the market, where the solar cells were no longer even slightly visible under the dial. During the mid-2000s, wristwatch sales improved for Citizen thanks to further development of the Eco-Drive line and integration of with the 2002 Eco-Drive line. Eco-Drive Concept Models [ ] Since 2009, Citizen has developed Eco-Drive Concept Models as technology demonstration and marketing tools.
These Eco-Drive Concept Models are generally shown at exhibitions and produced in limited editions. The Concept Model 2011 was the Eco-Drive SATELLITE WAVE that has a movement that can receive from. This makes radio-controlled timing possible in remote areas that are not serviced by land based radio time signal stations. In 2012 Citizen announced the Eco-Drive RING Concept Model.
This watch features a ring-shaped solar cell surrounding the watch case sidewall. Hazel 3 Keygen. Recent history [ ] According to Citizen, by 2011 80% of their wristwatches featured Eco-Drive, and the company saw Eco-Drive type watches as the focus of new generations of watches. In 2012 Citizen offered over 320 Eco-Drive watch models in various types, styles and price ranges.
Eco-Drive technology [ ] Light as power source [ ] Most Eco-Drive type watches are equipped with a special charged by an located behind the. Light passes through the crystal and dial before reaching the photocell.
Depending on the electronic movement, a fully charged secondary power cell could run with no further charging from 30 days to 3,175 days (8.7 years), though most Eco-Drive men's watch models offer a six-month power reserve. If kept from light for an extended period, some Eco-Drive movement models can hibernate, where the hands of the watch stop and the internal quartz movement continues to track the correct time. When subsequently exposed to sufficient light, the hands move automatically (without human intervention) to the proper positions and resume regular timekeeping. Temperature difference as power source [ ] Citizen Eco-Drive Thermo watches were introduced in 1999 and use the temperature difference between the wearer's arm and the surrounding environment as a power source. The rare Eco-Drive Thermo watches use the to generate that powers the electronic movement and charges the secondary power cell. In the sun or in the tropics the ambient temperature can come close to or exceed the temperature of the wearer's wrist causing the watch to stop generating thermo electricity. In case no power is generated, an Eco-Drive Thermo movement will save power by moving the second hand in ten second increments until the production of thermo electricity is resumed.
Citizen has stopped making Eco-Drive Thermo watches. Hybrid Eco-Drive movements [ ] Citizen also built an powered watch, the Citizen Promaster Eco-Duo Drive (released in December 1998). Novel to this watch was the use of both mechanical power as well as a solar cell to power the electronic movement and charge the secondary power cell. This model was an attempt to enter higher-priced markets (at a cost of around $1,000 USD).
The Eco-Duo Drive technology failed to attract consumer interest and Citizen has since stopped making use of the unique movement. Solar cell and secondary battery life expectancy [ ] According to Citizen, experimental data showed the solar cell and secondary battery will last for more than 10 years.
According to Citizen Europe, laboratory tests showed that after 20 years the secondary battery retains a power storage capacity of 80% of its initial capacity. Maintenance [ ] For and diving Eco-Drive watches Citizen recommends a watch exchange every 2 or 3 years to preserve their water resistance because watch gaskets, which form a watertight seal, degrade as they age. Further, Citizen recommends maintenance for Eco-Drive watch movements in regular intervals in order to extend the life of the watch movement, since the gears used in running watch movements are subject to slow wear.
Citizen states that their for Long-Lasting Precision Equipment when used in watches, timepiece movements remain smooth for a long time as the oil does not harden even after 20 years. Gallery [ ] •. Citizen Watches Australia. Archived from on 18 July 2014. Retrieved 12 February 2015.
