Elegance meets dependability and sport performance in Automatic Watch #9110 from the Invicta Men's Pro Diver Collection. This timepiece features a black dial with a combination of dot, stick, and triangular indices, a convenient date display at three o'clock, and a trio of luminous hands, along with small stick indices marking each minute on an outer dial. Also showcasing a stainless steel unidirectional bezel with a black finish and bold indicators, including Arabic numerals at the 20, 30, 40, and 50 minute marks, this watch employs an antireflective mineral crystal to protect its face, and it utilizes Japanese automatic movement for extreme precision. It is held in place by a sleek, black rubber band with a buckle clasp, and it is water resistant to 660 feet for true dive functionality.

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.

Automatic Watches

Automatic watches donot 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).
