The shock-resistant design of the Casio Men's G-Shock Atomic Tough Solar Watch makes it a one-of-a-kind timepiece. This tough watch is constructed with a durable black resin case, a stationary stainless steel bezel, and a black resin wristband with an adjustable buckle clasp for a personalized fit. A durable mineral window shields the digital-gray dial face, which features the time display, as well as the day, date, and month. The digital-quartz-powered watch includes adjust, mode, split/reset, and start/stop function buttons to fit your activity, as well as subdials that track battery life. It is water resistant to 660 feet.
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.

I got tired of the dial window on my cheap models scratching because they were made of plastic.
I did some research and learned to avoid the cheap ones made of acrylic (plastic).
I started looking for models made of tougher glass which is easy to do here at amazon.
If you click on a watch for the description and scroll down until you see the blue "Product Description" on the left will be a link that reads "Dial window material type"
if you click on it reads:
The covering of the watch dial. Acrylic, mineral, and sapphire are the three types of crystals commonly used in watches. Acrylic crystal is an inexpensive plastic that allows shallow scratches to be buffed out. Mineral crystal is composed of several elements that are heat-treated to create an unusual hardness that helps resist scratches. Sapphire is the most expensive and durable crystal, approximately three times harder than mineral crystals and 20 times harder than acrylic crystals.
I was unable to find any made of sapphire and figured it very $$$ so I went with one made with a mineral dial window and am very happy. Its recessed and feels like glass and I'm not worried about it scratching.
The band is also made of very durable but comfortable material.
Here is the list of features:
* Quality Japanese-quartz movement
* Tough Solar Power; shock Resistant; auto EL backlight with Afterglow; 4 daily alarms and 1 Snooze Alarm
* Chronograph measures up to 110 seconds
* Time recorder; memory capacity: 30 records (each record contains month, day, hour, minutes, seconds); hourly time signal
* Water-resistant to 660 feet (200 M)
I often use count down timers with my watch but this particular model replaced the count down timer with a time recorder?
I have no use for this but guess it may be useful for some to record the exact moment 30 times?
Also if they deem this odd feature necessary on this model why not leave the much more popular count down timer?
That being said, it still has multiple alarms which I use and also has the optional hourly beep.
I like the look/style, the slight red with the stainless is a nice/unique look and worth the trade of the countdown timer.
Don't forget the solar power, atomic time keeping and the optional (I like it) auto back light which turns the back light on when you turn your wrist to check the time in the dark, nice!
I hope this was helpful (at least you know there is not a countdown timer)
I'm considering buying a 2nd one of these as a backup, I like it so much!
The watch itself has so far exceeded my expectations. I've owned numerous G-shocks before and some dressy-type analogue watches but I've always hated changing batteries and also time accuracy had been a bit of a problem which is the primary reason for getting this watch. It arrived fully charged and even with no further light exposure it's supposed to hold a charge for 11 months which is great. The charge level hasn't moved from the H (high) position since getting the watch, with minimal light exposure. Also, the watch enters Sleep Mode when left in a dark environment for an extended period of time (such as overnight) to conserve energy. It automatically wakes up when it senses enough light, when you lift and angle the watch towards you or if you press any button. The feature worked flawlessly.
The watch is a lot nicer looking than in the pictures. And while it's a little flashier than my other G-shocks, it's still somewhat conservative looking with some nice polished and brushed metal accents. It's also not as big or as thick as I expected it and it fits without any issues under the sleeve of a dress shirt.
One of its main functions that I really wanted was the atomic time sync. I was concerned that being so far away from the station in Fort Collins (well outside the core 600 mile radius) would pose a problem. Well the watch was shipped and sat for at least four days inside a well packaged multi-layered box, and to my surprise the watch arrived and showed that it had synced successfully while in the box on the morning of delivery. I then left the watch sitting on its side overnight in our kitchen, at least 20 ft away from the nearest window, which isn't the recommended place to put it for syncing, and again I was very pleasantly surprised that it had no problem syncing overnight even from that location and position.
The buttons are well recessed so it's almost impossible to accidentally press any, unlike my last G-shock. But at the same time they're very responsive so it didn't take much effort to press them. The mode cycle is typical Casio so if you're familiar with any of them you'll feel right at home with this one. It has 5 alarms, with an hourly beeper and a stop watch. It also has a world clock allowing you to toggle between cities to show their current times. One of the nice features of this watch is that it can automatically set daylight savings time so you never need to remember when to do it. In all honesty I haven't used or tried the Time Record feature so I don't know how well it works but apparently it can record the time (date, hour, minute, seconds) of 30 events and store them. I'm not sure how useful that feature is but it's there.
The right-most of the three round dials at the top of the face provides a quick-glance view of some settings, such as alarms, hourly beeper, DST, Auto Backlight, etc... The middle dial shows battery charge level and the left dial shows the percentage of the hour that has passed (kind of like looking at the minute hand of an analogue watch) which is neat. The main face shows the time in either 12H or 24H as well as date and the day of the week. It also shows the time zone (e.g. M for Mountain Time Zone).
I do want to briefly mention the Auto EL which is a feature that's off by default. When activated, when you twist your wrist (the arm motion when you want to look at your watch), the back-lighting turns on for 1 second. Unlike my previous G-shocks with Auto EL, the nice thing about this feature on this particular model is that it determines how much ambient light there is so that when it's bright enough to see without the backlighting it doesn't turn on, to preserve battery life. I presume this auto-light-detection feature is unique to the Solar powered G-shocks as I'm assuming it's using the solar panel's photo cells to measure ambient light. In practice, the feature worked exactly as advertised in that it never came on when there was enough light but I found the wrist motion wasn't always detected consistently which is both good and bad. Good in that accidental motions never registered, bad in that sometimes it didn't light up when you wanted it to. I found controlled and deliberate twisting of the wrist yielded the most consistent results.
The strap on this watch is great. Its outer surface is textured, not only making it look sharp but also seems as though it would show less scratches and marks. I found the watch on the whole very comfortable, especially after a few days when the strap started to form to my arm.
All in all, the only one negative I can say about this watch is the tiny manual which isn't all that easy to read or follow. Casio, in their wisdom, bundled the same manual for 3 different watches with three different displays, albeit sharing the same features, making it a little tricky to figure out what a specific feature would look like on this watch. Personally I found downloading the manual online from Casio and viewing it on my 24" display a lot easier than the tiny included book. Having said that, if the time-sync feature and solar power continue to work as advertised then this watch is a definite keeper for the long term. It's highly recommended.
