Details: Be prepared for a night out on the town or a day's diving the reefs with Invicta's stylish Ocean Ghost Collection watch, a precise diving watch with an automatic movement, and water resistance up to 660 feet (200 meters). It features a round, shock-resistant silver stainless steel case with embossed unidirectional rotating bezel. The copper dial background is accented by silver triangular dial markers and Tritnite luminous hands (with seconds hand). The silver stainless steel bracelet band mixes brushed and polished pieces. Other features include an antireflective mineral crystal with magnifier, Cabochon crown, see-through caseback, and date function at 3 o'clock.
An automatic watch is a mechanical watch that is self-winding. the movement of your wrist and body causes the rotor--a weight attached to an automatic winding mechanism--to wind up the watch. This automatic watch has 21 jewels, which are ruby stones that the gears turn on to protect the metal parts from grinding together. An automatic watch needs no battery, but it will stop if now worn for over a day or if you have been physically inactive for an extended period of time. If this happens, wind the crown ten times clockwise to start the watch and five it some reserve power.
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.
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).
