Casio Men's G-Shock Classic Ana-Digi Watch #G100-1BV

The simply designed Casio G-Shock Classic analog-digital watch for men offers shock resistance that's great for your most vigorous sporting activities as well as anti-magnetic properties. The durable round black watch case measures 47mm wide (1.85 inches), and it's matched to a comfortable black resin sports strap. Timekeeping features include a 1/100-second stopwatch with a 24-hour capacity and elapsed time mode, dual time for tracking a second time zone, daily alarm, and 12/24-hour formats. Other features include an Auto Calendar (pre-programmed until the year 2039), ±15-second accuracy per month, Afterglow backlighting, and water resistance to 200 meters (660 feet)--which will stand up to the rigors of recreational scuba diving.

Note: Though this watch is designed to withstand exposure to magnetic force, you should still keep it away from machinery and appliances that generate a strong magnetic field.

G-Shock - Absolute Toughness

With the launch of its first watch in 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. Armed with cutting-edge technology developed for pocket calculators, Casio entered the field confident it could develop timepieces that would push watch technology forward.

Casio’s G-Shock line was created on just such a directive: to build a watch that never breaks. And in 1983, this product was developed to shatter the notion that a watch is simply a fragile piece of jewelry that needs to be handled with care.

G-Shock is renowned as the world’s toughest watch and is in the midst of a huge renaissance since its 25th anniversary celebration last year. It is the best trending watch brand in the industry right now and thanks to its toughness and durability as well as it’s cutting-edge technology, it is among the best values in not only timekeeping but all personal accessories.

In addition to toughness, 200 meter resistance and fantastic cutting edge and hip styling some G-shocks also have such technology as Tough Solar Power for battery life of 20-30 years (great for our planet), Atomic timekeeping for the more precise time available on earth as well as unique features like moon phase and tide graphs.

G-Shocks come in a variety of styles including Rubber/Resin bands, Solid Stainless Steel and even Titanium.

Since it’s launch, Casio’s G-Shock continues to evolve and push the envelope. The non-stop, self-adjusting (solar-powered atomic-timekeeping) G-Shocks featured in the Amazon.com assortment are the latest, greatest example of this evolution!

The Casio Story

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.
