  2. Eco-Drive - Wikipedia

    en.wikipedia.org/wiki/Eco-Drive

    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 Seebeck effect to generate thermo electricity that powers the electronic movement and charges the secondary power cell. In the sun or in ...

  3. Automatic quartz - Wikipedia

    en.wikipedia.org/wiki/Automatic_quartz

    Automatic quartz is a collective term describing watch movements that combine a self-winding rotor mechanism [1] (as used in automatic mechanical watches) to generate electricity with a piezoelectric quartz crystal as its timing element. Such movements aim to provide the advantages of quartz without the inconvenience and environmental impact of ...

    The Spring Drive uses a conventional mainspring [3] and barrel [4] along with automatic and/or stem winding to store energy, just as in a mechanical watch. [3] However, the escapement and balance wheel in mechanical watches is replaced by Seiko's Tri-synchro Regulator system, a phase-locked loop wherein a rotor, which Seiko refers to as a "glide wheel", is powered by the mainspring barrel via ...

  7. Overdrive (mechanics) - Wikipedia

    When it is switched on, an automatic transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [40-45 mph or more] depending on the load). When it is off, the automatic transmission shifting is limited to the lower gears. Overdrive should usually be selected when the average speed is above 70 km/h (40-45 mph).
