Amazon.com Product Description

Understated and classic in design, the Ingenieur line of IWC watches continues the 50-year tradition of simplicity of function and high accuracy in timekeeping. This stainless steel timepiece features an automatic 79350 calibre chronograph movement, small seconds hand with stop function and a chronograph with a central seconds hand and 30-minute counter. And since the 4 Hz movement is able to display times to an accuracy of one-eighth of a second, the dial includes an outer tachymeter scale for measuring time over distance.

Sublimely designed, this watch integrated the chronograph push buttons into the case and offers a raised bezel with polished highlights and screw-down accents. The blue dial offers a patterned center, chrono subdials at the top and bottom, luminous stick markers, small minute indexes, and baton hands (with luminous stripes and seconds hand). Other features include a soft-iron inner case for protection against magnetic fields, anti-reflective sapphire glass crystal, a 31-jewel movement with 28,800 vibrations per hour, 44-hour power reserve, and water resistance to 120 meters (400 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving.

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.
