Sadly, the GA 100 A1A in black utterly and completely fails at this core task. There is absolutely no way for a typical user with normal vision under normal lighting conditions (both indoors and outdoors) to read this watch. Other reviewers have pointed this out and, to my detriment, I ignored them.
As a long-time G-shock aficionado ( I currently own and regularly wear 6 G-shocks) I am sadly returning this watch to Amazon for a full refund. I am also raising my voice to send a message to the G-shock folks in Japan: it doesn't matter how stylish and rugged and affordable and cool the watch is, if you can't tell what time it is, you're just wearing a big rubber bracelet!
People complain that they cant see the time that's true to a degree, it is very dark but I can read the numbers fine. If you tilt it towards the light you can see them fine but i think it adds to the black look even more so I don't mind it. I think it would be better if the light instead of being on top like that, that the LCD portion would illuminate.
The light is a complaint of a lot of people because it only highlights enough to catch the time on the hands, not enough to see the digital readout, but if you are truly going for a stealth watch (not sure why you would want to unless you are in the military or law enforcement) you would want the light to be minimal, not a blinding beam that highlights the entire face.
I have other atomic solar G shocks that probably function a little better overall, or if you ever needed one watch that never needed batteries would be a better choice, but for everything this watch it, I love it and have been wearing it every day, it is too sharp to keep in the watch case.
1. Unable to read the digital LED information on the watch, except in very strong sunlight, with reading glasses. The LED information is not only small and non-illuminated, but is NOT affected by pushing the LIGHT button on the watch. The ONLY thing you can read on this watch is the analog hands- and they are the ONLY thing the LIGHT button does actually illuminate.
2. I bought this watch because the brand, control and model designations are quite garish on these Casio G-Shock watches. If I actually own the watch, I KNOW which button controls which function- that is what the instruction booklet is for. I do not require high contrast labels to inform me of the brand, model and function. (The pedals on my car are not labeled GAS, BRAKE, or CLUTCH.) This watch had "blacked out" labels- still engraved, but not garish. Well, all the information, except the analog hands, is also "blacked out". Useless.
3. The ALARM function is worthless, since the tones emitted to advise, or wake, you at the set time are not audible. With the watch placed next to my ear, like 1" away, it was so faint I thought I was imagining the beeping.
OK, it's a cheap watch, but supposed to be rugged and functional. It may be rugged, I will never know. To buy a watch that one cannot read is the definition of stupidity.
