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.


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.

Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

    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.

    As someone else commented, this watch is reminiscent of the Omega "Planet Ocean" watch, as worn by Daniel Craig in the latest James Bond film. I wouldn't call it a knockoff, it just has a similar style to it. For under $50, it's a solid, attractive, and classically masculine watch, and definitely fills the role I purchased it for.

    It even features a Bond style gadget! The illuminator button on the top right activates (2) very bright LED lights behind the 12 and 6 positions... the LED's stay lit for a couple seconds and are very bright white.... you could easily use this watch as a flashlight in a dark room. The watch also features a screw down crown, which I think is a nice high-end feature for such an inexpensive timepiece.

    Unlike almost every other review here, I had no problems at all with the strap... Mine is very soft and comfortable. Not sure if Casio changed it, or if I just have different tastes, but really, I find the watch a pleasure to wear as is.

    Sure, this watch is no Omega or Rolex, but for the money, I think it's a solid, attractive, and functional piece, that packs a hell of a lot of style into an affordable package.


    Just wanted to add, I've had the watch for some time now, and I still have no problems with the strap... again, not sure if Casio changed it out, or if I'm just in the minority, but I think it's quite comfortable.

    Also, another positive feature is the luminosity of the watch... after a normal day's wear, I have no trouble seeing the watch in the dark, and don't even need to use the LED function to tell the time. They used two colors of luminous paint as well... a light blue for the markers, and traditional green for the hands, which is kind of neat. All in all, I still can't believe this is a sub $50 watch. Great deal!

    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).

    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.

    So here's the thing: It is a remarkable watch. Heavily built with seemingly solid construction. Very easy to read, beautiful to look at and the other reviews are right: The two LEDs are stunningly bright. You will NEVER have a problem reading this in the dark. It is an exceptional time piece and a ridiculous value. The ratchet works very well, the screw down crown is as smooth as you would expect from a very high end watch. This could easily be priced for a few hundred and would be worth it except for one massive flaw: The band is beyond BAD. It may be one of the great engineering failures of the modern era. It is unbearably stiff and has been designed to dig into your wrist like some kind of medieval torture device. Do not buy this watch unless you buy a replacement strap right up front. I did as a previous review suggested and got the Modena 22mm rubber strap with deployment clasp. I took it out of the box and inside of ten minutes the soft rubber it is made with had begun to collect dust and debris... Which it hung on to with amazing tenacity! On top of that, the clasp is flimsy and poorly made. I tossed that into the can along with the original band. I next ordered a 22mm Seiko diver's band also from Amzaon. Success at last! A tad stiff but a nice tight fit for the watch. Simple black with a standard buckle. Looks like it was the original strap and is very comfortable.
    Here's the item/part number: 001-seikoOrigRubber22
    Well worth the money.
