Review & Description
Classic dive watch styling with Swiss reliability, the Invicta Men's Subaqua Collection Automatic Chronograph Stainless Steel and Black Watch functions without a battery -- it is powered automatically with the movement of your arm. This impressive timepiece also features a two-tone brushed and polished stainless steel case and a band that closes with a fold-over safety clasp. The stainless steel case provides an ideal foundation for this watch's rotating bezel with minute markers and the attractive dial. The dial has luminous hands and orb hour markers and there are three subdials at the six, nine, and 12 o'clock positions. There is also a date window at the three o'clock position to help you keep tabs on your busy schedule. For added style, Invicta included a large crown and two buttons on the right-hand side of the case. Other features include precise Swiss automatic movement, a durable flame-fusion crystal, and water resistance to 1640 feet (500 meters).
Automatic Watches
Automatic watches do not operate on batteries. Automatic watches are made up of about 130 or more parts that work together to tell time. Automatic movements mark the passage of time by a series of gear mechanisms, and are wound by the movement of your wrist as you wear it. The gear train then transmits the power to the escapement, which distributes the impulses, turning the balance wheel. The balance wheel is the time regulating organ of a mechanical watch, which vibrates on a spiral hairspring. Lengthening or shortening the balance spring makes the balance wheel go faster or slower to advance or retard the watch. The travel of the balance wheel from one extreme to the other and back again is called oscillation. Lastly, automatic movements come in different types, including movements that are Swiss-made, Japanese-made, and more.
Also referred to as self-winding, watches with automatic movements utilize kinetic energy, the swinging of your arm, to provide energy to an oscillating rotor to keep the watch ticking. They're considered more satisfying to watch collectors (horologists) because of the engineering artistry that goes into the hundreds of parts that make up the movement. If you do not wear an automatic watch consistently (for about 8 to 12 hours a day), you can keep the watch powered with a watch winder (a great gift for collectors).
