For 25 years Casio G-Shock digital watches are the ultimate tough watch. Providing durable, waterproof mens digital watches for every activity. G-Shock is the ultimate tough watch. It was born from a developer's dream of "creating a watch that never breaks." Guided by a "Triple 10" development concept, the design teams sought a watch with 10-meter free-fall endurance, 10-bar water resistance and a 10-year battery life.
A simple, yet intricate dial set into the strong G-Shock design results in a timepiece with a distinctive personality all its own. The face utilizes metal parts to create a variety of levels that makes information presented easy to read. Features include a large screw lock crown, 1/20-second analog chronograph, date display and more. Black resin band analog watch with black, white and red face.

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.

the gs gac100-1a and its different colored cousins came out early last year . i have always been interested in owning a g-shock to add to my modest collection of about nine or ten watches . all the other watches i own are stainless steel and mostly black and most of them have matching bracelets . i am not really into watches with straps and i am going to replace the resin strap that came on the gs gac100-1a with a 28mm wide black stainless steel bracelet . ( assuming the modification can be accomplished ) . the gac100-1a case is also resin . i wanted a shock resistant and 200 meter water proof watch to wear for outdoor activities and for motorcycle riding and sports . i have some semi pricey accutrons and a steinhart and a couple of seikos but i would never wear those watches doing " shocking " and wet activities . a good watch - even a good dive watch like the steinhart ocean black dlc - will be destroyed if i use it during harsh outdoor sports and sweaty bike riding . the manufacturers of fine sports watches claim that they are water proof for 200 meters and somewhat shock proof but i think they just say that to sell watches . if i wear a decent timepiece during outdoor sports it will either be seriously deteriorated or dead despite what the manufacturers claim . therefore i got a g-shock to wear so it can take the abuse instead of my nicer stainless steel watches . i got the plain black version . when this g-shock was released last year casio had them priced at over $200 . they understandably did not sell very well at that price . g-shock fans enjoy gee wiz features and blinking digital windows and night lights . the gac100-1a has none of those features . there are only two buttons ( on the right side ) and a screw down crown between the buttons . the gac100-1a is all analogue . there is not a single gee wiz digital window on the entire face as you can see in the amazon pic . all my more expensive watches are also all analogue . i could never read a digital watch very easily anyway . ( of course all that is about to change with the imminent arrival of iwatches coming out in the next few years ) . the gs gac100-1a has three essential complications . it tells the time with very clear white hands against a black face . it marks a time interval with an all analogue stopwatch function down to 1/20 second . ( including split time etc ) . and it has an easy to read analogue date window at three o'clock . the gac100-1a does not light up or tell when the moon is full or when the tide is out or where 360 degree north is or how high above sea level or how below sea level i am or what time it is in thailand . i think g-shock fans were underwhelmed by this simple shock proof water proof ( 660 ft ) all analogue watch with absolutely no gimmicks . it doesn't receive time keeping adjustments from denver and it runs for three years on a regular battery . i dislike solar powered watches because they are pointless . i do not want my watch receiving time signals from anywhere . i believe all the advanced technology that g-shock has designed is quite impressive . but i also believe the coming era of smart watches ( which i refuse to ever wear ) will completely obsolete all the clever digital gimmicks that g-shock has implemented over the years --- with the obvious exception that the new iwatch will not be nearly as durable as a g-shock .so i chose the basic all analogue gs gac100-1a ( now on line for less than a hundred bucks ) because it is simple and durable and shock proof . this gs gac100-1a will be a collector's item because everybody will be talking to their wrist five years from now . i love the gac100-1a . it feels great ( even with a resin band ) and it does all i need it to do . it is easy to read and shows me the date and has a stop watch . i personally do not need anything else . i don't care what time it is in berlin .
thanks for listening

Luminous hands present and functional, seem to have no problem glowing for a while. Time will tell if they hold up and be able to be seen late into the night. Date is a continuous wheel 1-31, so just have to be a bit more aware of the days towards the end of the months to set it ahead as needed, not a problem though.
Overall I like the few functions it has, and it is a very nice and sharp-looking watch. I will update as I get more experience and opinions of the GAC100-1A. (~$98)
