Casio Men's GW9200-1 G-Shock Riseman Alti-Therm Solar Atomic Watch
The Casio Men's G-Shock Riseman Alti-Therm Atomic Solar Watch #GW9200-1 is a technical timepiece with athletic style. Featuring a unique three-layer twin sensor that measures altitude, barometric pressure, and temperature, the ability to track information over time, and Multi-Band Atomic Timekeeping, which lets calibration radio signals keep the time display accurate, this watch is ready to take on big adventures. Add Tough Solar Power, an Auto EL Backlight, a world clock featuring 29 time zones, and five daily alarms into the mix, and it's tough to see how you could be more prepared for whatever lies ahead. Also offering a durable mineral window, resin band with buckle clasp, resin case, and digital-quartz movement, this watch is water resistant to 660 feet

Casio Men's GW9200-1 G-Shock Riseman Alti-Therm Solar Atomic Watchthe 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.

The means by which a watch keeps time, and often includes the power source. For example, a watch with mechanical movement uses a spinning balance wheel powered by a tightly wound spring. A watch with quartz movement measures the vibrations in a piece of quartz and is often powered by a battery. Quartz case diameter:44.8 millimeters dial window material

The covering of the watch dial. Acrylic, mineral, and sapphire are the three types of crystals commonly used in watches. Acrylic crystal is an inexpensive plastic that allows shallow scratches to be buffed out. Mineral crystal is composed of several elements that are heat-treated to create an unusual hardness that helps resist scratches. Sapphire is the most expensive and durable crystal, approximately three times harder than mineral crystals and 20 times harder than acrylic crystals. Mineral water resistance:

Bidirectional: A bezel that rotates both clockwise and counterclockwise. It may have printed or engraved markers, numbers, or directional markers.
Interchangable: A bezel that can be removed and replaced by another bezel. In most cases, a watch with an interchangeable bezel comes as a set.
Slide-Rule: A rotating bezel that is printed or engraved with a logarithmic scale, metric scale, or other scales. It is used with fixed mathematical rules, allowing the wearer to perform directional/navigational or mathematical calculations.
Stationary: A bezel that does not rotate.
Tachymeter (or Tachometer): A bezel that allows the wearer to calculate speed based on travel time over a fixed distance traveled. For this reason, most tachymeter bezels will have markings or scales printed or engraved on the surface.
Unidirectional: A bezel that rotates one way. Most unidirectional bezels rotate counterclockwise. In many dive watches, it is used to measure elapsed time spent underwater.
