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.Pro Diver Collection Plunge into any horizon using the steadfast guidance of the Invicta Pro Diver. Stylishly classic, internal workings are forged with variations of either Swiss chronograph or 21-jewel automatic movements and willingly navigate in depths up to 300 meters. Built with confident prowess, the fortitude with which these timepieces function makes the Pro Diver the quintessential in performance. Screw Down Crowns: Many Invicta watches are equipped with a screw down crown to help prevent water infiltration. This is most common on our Diver models. In order to adjust the date and/or time on such a watch, you must first unscrew the crown before you can gently pull it out to its first or second click stop position. To do this, simply rotate the crown counterclockwise until it springs open. When you have finished setting the watch, the crown must then be pushed in and screwed back in tightly. Not doing so will cancel the water resistance of the watch and will void all warranties from the manufacturer. Overall, this process should not require a lot of effort or force. With its most inspired creations yet, Invicta demonstrates its technical and design prowess, offering timepieces of style for extreme value."We have long held firm to the belief that supremely crafted timepieces can be offered for extremely modest sums. It is the founding principle of our flagship and the radical notion that still drives us today. By being true to our convictions, we will continue to turn the balance of power, and deliver true Swiss luxury to anyone who desires it.
