Tissot, a watch manufacturing company, was founded in 1853 by Charles-Felicien Tissot. Headquartered in Le Locle, Switzerland, it is now a member of the Swatch Group, the largest watch distributor and producer in the world, according to the Tissot website. It is the official timekeeper of NASCAR, FIBA, AFL and other world championships. In watches, the movement is the interior part of the watch, as opposed to the outer casing.
Automatic, or self-winding, movements are activated by a rotor in Tissot watches. When you move your arm or wrist, the rotor moves inside the watch. This, in turn, winds the mainspring. These movements require no batteries. Its accuracy hinges upon the original timing of the movement, the quality of the manufacturing process and the wearer of the watch.
Mechanical, or manual winding, requires that the wearer wind the watch by turning the crown, or the knob connected to the rotor, often located at the top of the watch. Tissot's mechanical watches require no batteries, and their accuracy depends on the original manufacturing and the memory of the wearer to keep the watch properly wound.
In a Tissot quartz movement, a uniquely designed synthetic quartz crystal transmits electronically controlled oscillations. A counter records the number of oscillations and moves the second hand one second forward once it has counted a certain number of oscillations. Tissot's quartz movements acquire the energy for this process from a battery, but they yield superbly accurate results.
Tissot's autoquartz movements combine automatic movements and quartz movements. Rather than using a battery, the energy to generate oscillations in the quartz is acquired from movements of the wearer's arm and wrist. This movement can be recharged by winding the crown of the watch.
