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.

At that point in time, I've always thought that solar powered watches cost at least $500 or more. Imagine my delight at finding a cheap solar powered watch!
However, my joy was pretty short-lived. A couple of weeks down the road, while wearing it, it switched off right in the middle of the day! Lunchtime in fact, while I was out walking around in bright sunlight! Hands stopped moving, LCD screen blank except for a "LO C" blinking indicator. It was impossible since I have never seen the watch move from the "Hi" battery level indicator before.
An hour later it turned itself back on while I was back in the office. Hands moved to the correct time, LCD screen was back on, and the battery indicator said "Hi".
A few incidents similar to this happened a few times, in the following months. So much so that I decided to junk this watch and threw it inside my drawer, never touching it for about 8 months or so.
Recently, I took it out of the drawer again and the watch turned itself back on when it was exposed to light. Battery Indicator said "MID". So I left it on the window sill for 3 days straight, hoping that it stays at "Hi".
On the 4th day, I wore it out. We went to the movies, and right in the middle of the movie when I wanted to check the time, I pressed the backlight and... nada. No reaction. I tilted the watch to let the light from the movie shine on it and saw the watch had turned itself off AGAIN, about 40 mins ago (checked time with my mobile phone).
Somewhere along the way, still during the same movie, the watch turned itself on again, because suddenly I heard it do the hourly beep thing. Now, I know for sure that the watch was not exposed to light in any way, and even if it did, the light from the movie is nowhere near powerful enough to charge it up to turn it back on.
My take is this - it's too cheap to send it back to Casio for servicing. If it works while you wear it, enjoy it. It will suck when it doesn't.
The other thing about Casio analogue watches which I didn't like much is that the "luminous paint" on the hands is almost useless. It glows for like only 15 mins and then stop glowing. Practically useless. It's not just on this watch - I own a couple of other Casio digi-ana watches from the G-Shock line and every single one of them had the same problem of short-lived glowing luminous hands and markers.
When, last summer, I decided that I needed a new watch, two problems presented themselves. The first is that Casio no longer appears to make the kind of calculator watches I like. The second is that I've reached a point in my life where I need something a little more elegant-looking. Thus, I started to look into hybrid analog-digital watches. Eventually I settled on the AWS90D-2AV model featured on this page.
First, it has very sleek, rounded contours. This is important because a recent Casio Databank, while a very nice watch, had rough edges which shredded my shirt and suit sleeves, causing hundreds of dollars of damage to my wardrobe. (Yes, the Databank too is sitting in the Watch Morgue, still humming away the last time I checked.)
Second, the AWS90D is quite pretty to look at, with an appealing mix of steel and blue as the picture on this page will show you. When exposed to bright sunlight for a few minutes, the fluorescent strips on the dial have almost an iridescent quality to them.
Third, the watch is solar-powered. In theory at least, it should work for about ten years, until the battery no longer accepts a charge. Of course, by then no doubt I'll have gotten a new watch, due to the usual corrosion issues.
Fourth, it comes with a stopwatch and "dual time" mode, two features I've found very useful over the years.
And finally, it's incredibly accurate. It gains only about three seconds a month. The only clock in the house that's more accurate has a radio receiver to keep it in synch with the Atomic Clock in Boulder. I reset the watch at the start of each month, and otherwise just leave it alone. If it's mid-month, I know it's 1.5 seconds off.
One minor issue which I had right away was the size of the band. Too big for my wrist, it tended to slide around uncomfortably. Your best bet, should you encounter this problem, is to go to a jeweler, where they should have a special tool which can remove a link or two from the band, thus shrinking it. With a jeweler's screwdriver, a large paper clip, and a certain amount of dogged tenacity I was able to do the operation myself at home, but I don't recommend this for just anyone.
A second issue, again minor, is that when you need to set the watch back an hour, either for a time zone change or for the end of Daylight Savings Time, the hands have to race forward 11 hours to reposition themselves. It would be nice if they could just run backward for one hour instead. But no big deal.
Alas, the watch does have one major flaw which makes it hard to live with. Because a solar-powered watch obviously depends on getting enough light to function properly, the AWS90D has various power saving modes and power level indicators for those long winter months when the wearer is staying indoors under weak fluorescent lights, and wearing long sleeves to boot. When the batteries get critically drained, the watch basically switches off. The hands stop moving and there is no more digital display. When the charge is restored somewhat, the watch switches back on and the hands catch up to where they should be, the watch having kept track of the time internally.
Alas, this feature has begun to malfunction. Twice in the past week, it has suddenly switched from the "Hi" indicator (full power) to "Low-C", which means deep power-down. Today it was during the lunch hour, when one might expect there to be plenty of light. This effectively left me without a watch; it didn't switch back on again until half an hour later, when I was almost back to the office, walking along in bright sunlight and holding my wrist up awkwardly. This really does defeat the purpose of having a watch.
So, as much as I hate the thought, it looks like I'm going to have to go shopping again. In the meantime, I'm sticking my watch on the windowsill to see if the afternoon sun can fortify it a little.
The worst part is if you look at Casio's warrentee the band and case are not covered.
My watch is now held together with epoxy - very fashionable! Goes good if you have glasses held together with masking tape.
My advise is move on and find a watch with a metal to metal connection from the band to the case. Don't buy this one!
