Amazon.com Product Description
This Casio Sea analog illuminator watch offers all the convenience and durability of a sports watch, with an adaptable style well suited for a work day. The large round dial is black with white and luminous indexes, two luminous hands, and a red arrow-tipped seconds hand. The black stainless steel bezel offers additional Arabic numeral and dot indexes and a one-way rotation to make timing easy. The bezel's distinctive cog-like edge also gives the watch a stylishly industrial edge. The date displays subtly at four o'clock, and a super illuminator light makes the watch easy to read at any time. The band is made out of rugged black resin with a buckle clasp. This analog quartz powered timepiece is water resistant up to 660 feet (200 meters) and offers a battery life of approximately three years. It is backed by a 1-year limited manufacturer's warranty.

Development of the Timepiece Business
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.

Customer Reviews

Very nice 200m water resist watch!
This is a great looking sports watch, and the light is really bright - it's a white LED both at 12 o'clock and 6 o'clock, so it allows for nice visibility in low light. The stainless steel case is nicely polished and looks very sharp. This watch really looks more expensive than it is, and I've had people ask about it when wearing it. It's an eye catching watch.

The MDV102-1AV is 200m water resistant, which means it can handle you going swimming, snorkeling, even some diving without much problem. This watch has a screw-down crown too, which makes it even more water resistant. The only thing to watch out for is washing the dishes, hot tubbing, or showering with it - warm/hot water isn't great for watertight seals on watches. I've heard it can weaken the seals and cause a leak.

The little marlin on the watch is a great touch, and the face is very easy to read. The white markers contrast really well with the black dial, and even have a mirror-like edge to them, which makes the markers stand out even more. The offset date at 4 o'clock makes it look interesting, too.

My only disappointment was the band - it's a hard rubbery band and not very comfortable. That's why I took off one star from my rating. Aside from the band this watch really rocks! To solve that, I bought a Timex Expedition Adjustable 16-20mm watch strap TX977761L, Timex watchband, Fast - Wrap Expedition, 16-20mm, Black, Adjustable, Long. It's for a Timex Expedition, so it says Timex on it, but it's a great velcro strap that's really easy to adjust and install on the Casio.

If you decide you want to change straps like me, just pop out the strap that comes with the Casio, pull out and save the little springs, then attach the Casio (using it's springs) to the Timex strap. Took 3 minutes and I love the adjustable Timex strap, it's very comfortable and dries out easily when it's gotten wet.

I definitely recommend this watch. It's well worth the money for the water resistance, and looks really nice!

Excellent Quality Diver's watch.
I had my eyes on this Casio Diver's watch for the last few months, but Amazon.com wasn't carrying it yet. I was so glad when I saw that Amazon started selling this watch. I just got this watch a few days ago and I have not taken it off of my wrist yet. I LOVE IT!! It's very accurate and it looks just like the James Bond watch.
The watch is very well built with high quality workmanship. It's also water resistant up to 200 meters. You can swim, shower and dive with this watch without worrying about water getting into it. The crown on the watch is a screw-in crown, so no water, dirt or dust can get into the watch. I also love the "Super Illuminator" light that this watch has. When you press the button that's located at the 2 o'clock position, the entire face of the watch lights up and stays lit for 3 seconds. The light is very bright and as bright as a flashlight. You can also let the light to stay on just by keeping the button depressed for however long that you like. The watch is not heavy on the wrist and it's very comfortable to wear. The watchband on this watch is also very comfortable and very durable.
I highly recommend this watch to anybody who is looking for a durable, accurate and nice looking diver's watch.

Best all-around
Pros:
Rotating top-ring, 200m water resistent, LED lighting. luminescent paint is two colors: green for hands, blue for hour markers. Screw-down crown, screw-down caseback (usually found on higher end diver's watches).

Cons:
Crystal "bulges" outward (prone to scratching), the inset luminescent marker on the topring does not glow very brightly/hard to see in dim lighting. Dial is not completely black, but more of a dark gray (Topring is completely black). Uncomfortable strap. Topring is hard to turn with fingerpads - I have to use my nail, especially underwater.

I've been windsurfing and sailing with this watch and it's been great. If you want a basic, durable diver's watch, look no further. At this price, this is the one to beat.
