The Casio Men's
Multifunction Analog Watch #EF305-1AV features a dramatic black dial face
that is protected by a durable mineral dial window. Contrasting indexes and
Arabic numerals offer at-a-glance clarity, and three handy sub dials track
the day, date, and 24-hour clock. A black resin band is accompanied by a
sturdy buckle clasp. Other details include a 10-millimeter stainless steel
case and silver-tone stationary stainless steel bezel. Highly affordable,
this sophisticated timepiece sets off your look with a fresh finish. It is
powered by quartz movement and is water resistant to 330 feet.
With the launch of its first watch in November 1974, Casio entered the
wristwatch market at a time when the watch industry had just discovered digital
technology. As a company with cutting-edge electronic technology developed
for pocket calculators, Casio entered this field confident that it could
develop timepieces that would lead the market.
In developing its own wristwatches Casio began with the basic question,
""What is a wristwatch?"" Rather than simply making a
digital version of the conventional mechanical watch, we thought that the
ideal wristwatch should be something that shows all facets of time in a consistent
way. Based on this, Casio was able to create a watch that displayed the
precise time including the second, minute, hour, day, and month — not to
mention a.m. or p.m., and the day of the week. It was the first watch in the
world with a digital automatic calendar function that eliminated the need to
reset the calendar due the variation in month length. Rather than using a
conventional watch face and hands, a digital liquid crystal display was
adopted to better show all the information. This culminated in the 1974
launch of the CASIOTRON, the world’s first digital watch with automatic
calendar. The CASIOTRON won acclaim as a groundbreaking product that
represented a complete departure from the conventional wristwatch.
Casio transformed the concept of the watch — from a mere timepiece to an
information device for the wrist — and undertook product planning based on
this innovative idea. We developed not only time functions such as global
time zone watches, but also other radical new functions using Casio’s own
digital technology, including calculator and dictionary functions, as well as
a phonebook feature based on memory technology, and even a thermometer
function using a built-in sensor. The memory-function watches became our DATA
BANK product series, while the sensor watches developed into two unique Casio
product lines of today: the Pathfinder series displaying altitude,
atmospheric pressure, and compass readings.
In 1983, Casio launched the shock-resistant G-SHOCK watch. This product
shattered the notion that a watch is a fragile piece of jewelry that needs to
be handled with care, and was the result of Casio engineers taking on the
challenge of creating the world’s toughest watch. Using a triple-protection design
for the parts, module, and case, the G-SHOCK offered a radical new type of
watch that was unaffected by strong impacts or shaking. Its practicality was
immediately recognized, and its unique look, which embodied its
functionality, became wildly popular, resulting in explosive sales in the
early 1990s. The G-SHOCK soon adopted various new sensors, solar-powered
radio-controlled technology (described below), and new materials for even
better durability. By always employing the latest technology, and continuing
to transcend conventional thinking about the watch, the G-SHOCK brand has
become Casio’s flagship timepiece product.
Today, Casio is focusing its efforts on solar-powered radio-controlled
watches: the built-in solar battery eliminates the nuisance of replacing
batteries, and the radio-controlled function means users never have to reset
the time. In particular, the radio-controlled function represents a
revolution in time-keeping technology similar to the impact created when mechanical
watches gave way to quartz technology. Through the further development of
high radio-wave sensitivity, miniaturization, and improved energy efficiency,
Casio continues to produce a whole range of radio-controlled models.
