Amazon.com Product Description

The Casio Men's Edifice Stainless Steel Multi-Function Chronograph Watch exists at the crossroads of comfort, style and functionality…which is where you should be. This dynamic timepiece kicks off with a 45.5mm stainless steel case and a stationary bezel with a textured edge. There are also pushers on both sides of the case, along with a protected screw-down crown on the right side. The watch's black dial is a flurry of function with a sliding inner bezel, silver-toned hour markers and hands, which are powered by quartz movement. The dial also features three chronograph sub-dials with 12-hour, 60-minute and 60-second displays, along with a date display window at the 3 'o clock position. The stainless steel three-link bracelet straps this watch to the wrist, while a fold-over push-button clasp with a safety ensures that it stays there. Finally, this watch offers water resistance up to 330 feet (100 meters).

The Casio Story

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.

The watch has an over-all appealing look... However, if you're an aviator and you're buying this watch for the bezel flight calculator - keep looking. The numbers are so small around the bezel you need a magnifying glass to see them. The watch movement itself seems to keep good time but the hands and hour indicators cannot be seen in the dark unless you put your flashlight on them for ten seconds but then why bother with glowing indicators? If you just want the looks of a flight watch with slide rule you'll probably be happy with this watch. Your getting a good stainless steel watch for the money but the probability of using it as a flight calculator are pretty slim.

This watch is a looker. Unfortunately looks aren't everything. After only having the watch for about 20 days the knob that controls the slide rule bezel fell out. While this knob could probably be replaced by taking the back off of the watch and aligning the hole where the shaft of the knob fits, I don't figure 20 days of wear is the proper time frame for this sort of thing to happen. Long story short, I'm returning it. A shame really because I do like the watch. Just wish the construction quality was a little better. I'll consider buying another Casio watch in the future but this purchase seems to be a bust.

Bit big watch though, yet the look is great. The instruction manual could have been more elaborate / detailed - it took me a while to figure out that i have unscrew and pull to set the time.
