Armitron is a watch brand manufactured by E. Gluck Corporation, headquartered in Little Neck, New York. [1] It was founded in 1975 by Eugen Gluck. As of 1999, Armitron had the fifth largest share of all watch purchasers, by brand, in the United States.
Armitron started making digital watches in the 1970s with LED displays. The LED displays consumed so much battery life that, in 1977, the company stopped production. [ 9 ] Armitron subsequently began manufacturing their digital watches with LCD displays, [ 1 ] which eventually became the industry standard.
Button, coin, or watch cells. A button cell, watch battery, or coin battery is a small battery made of a single electrochemical cell and shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high – resembling a button.
The movement of the watch draws its power from the rechargeable battery or capacitor. As long as the watch is regularly exposed to fairly strong light (such as sunlight), it never needs a battery replacement. Some models need only a few minutes of sunlight to provide weeks of energy (as in the Citizen Eco-Drive).
The earliest makers of watches with balance springs, such as Hooke and Huygens, observed this effect without finding a solution to it. Harrison, in the course of his development of the marine chronometer, solved the problem by a "compensation curb" – essentially a bimetallic thermometer which adjusted the effective length of the balance ...
Later specialized tool watch designs were introduced like the Promaster Eco-Drive Professional Diver 1000M Titanium BN7020-09E in 2017. This is a very large watch, the titanium watch case has a diameter of 52.2 mm and thickness of 22 mm and features a helium release valve, designed for mixed gas saturation diving at great depths.

Thus, prior to the 1970s, the Swiss watch industry had 50% of the world watch market. [11] In the early 1950s a joint venture between the Elgin Watch Company in the United States and Lip of France to produce an electromechanical watch – one powered by a small battery rather than an unwinding spring – laid the groundwork for the quartz watch ...
The AMC Amitron was an experimental electric subcompact car built in 1967 by American Motors Corporation (AMC) and Gulton Industries.It included many advanced features, including regenerative braking and advanced battery designs, to provide a 150-mile (240 km) range on a single charge.
