Amazon.com Product Description
Named after the vaunted British World War II fighter plane, the IWC Spitfire Double Chronograph automatic men's watch is a perfect timepiece for pilots or anyone who enjoys the ultimate in technical sophistication. It includes two separate stopwatch mechanisms in order to estimate two separate events of different durations. It also features two seconds hands, with one superimposed over the other. While one hand moves continuously, the other one can be whether stopped, started or reset to zero. The secondary stopwatch mechanism is controlled via a third button at the 10 o'clock position, while the main chronograph mechanism is operated by the two standard pushers on the right side of the watch. This large, imposing timepiece measures 42mm wide (1.65 inches) and the stainless steel case features a brushed silver finish. The silver dial face includes three chrono wave-patterned subdials, a full Arabic numeral display, small minute/seconds indexes around the exterior of the dial, and a day-and-date window at 3 o'clock. It's matched to a handsome quintuple-link stainless steel bracelet band. Other features include a 23-jewel automatic movement with 28,800 vibrations per hour, a 42-hour power reserve, and water resistance to 60 meters (200 feet)--offering protection from accidental splashes and snow spray as well making it suitable for swimming. An automatic (or self-winding) watch is fitted with a device (rotor) that automatically winds the spring by using the force of gravity. It needs no battery, but it will stop if you have been physically inactive for an extended period of time--as long as you're moving, the watch will stay powered. Swiss watchmaker Abraham-Louis Perrelet invented the self-winding mechanism in 1770. It worked on the same principle as a modern pedometer, and was designed to wind as the owner walked. About IWC
While founded in Schaffhausen, Switzerland in 1868, the International Watch Company (IWC) was created by an American--Florentine Ariosto Jones. The Jones calibre, the very first movement manufactured by IWC contained a wealth of advanced technical features. These included an elongated index to regulate the balance hairspring and a bimetallic cut balance to compensate for fluctuations in temperature. In 2000, IWC introduced the 5000 calibre, a new automatic mechanical movement with a seven-day power reserve and the legendary winding mechanism of the patented Pellaton system. In the aftermath of World War II, IWC became a company of international scope. Exports to the United States increased and the brand became best known for its specialty watches (now highly prized as collectibles), such as the Mark XI and Ingenieur--the first automatic IWC with a soft-iron inner case that protected the movement against magnetic fields.
