Invicta Pro Diver. Stylishly classic, internal workings are

meters. Built with confident prowess, the fortitude with which
these timepieces function makes the Pro Diver the quintessential

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).
