Boldly modern in style, this Invicta stainless steel men's watch features a precise Japanese automatic timing movement and a look that will complement both contemporary professional and casual wear. The watch case and bracelet band are made from surgical grade 316L stainless steel, and the case is topped by a unidirectional rotating bezel with engraved Arabic numerals at the quarter hours and triangles at the half hours. The black, oil-pressed dial face includes a mix of Tritnite luminous Arabic numeral and stick markers, minute indexes around the exterior, and luminous-tipped baton hands (with seconds hand). Other features include a magnified date window between 4 and 5 o'clock, scratch-resistant mineral crystal, and water resistance to 200 meters)--which will stand up to the rigors of recreational scuba diving.
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).
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.
Tritnite is a luminous material with an extended glow exclusively developed by Invicta in Switzerland and added to their timepiece hands and markers. When exposed to regular daylight, it will hold its glow for about 20 hours.
About Invicta
Latin for "invincible," Invicta was founded in La Chaux-de-fonds, Switzerland in 1837 by Raphael Picard, who believed that fine Swiss timepieces could be offered at modest prices. For more than a century, the company has created distinctive manual and automatic-winding pieces. In 1991, descendants of the Picard family reaffirmed the company's founding principle, and the invigorated Invicta has been growing ever since with one of the most widely diverse collections of precise Swiss timepieces on the market.
