From G-SHOCK, the watch that is constantly testing new limits in timekeeping toughness, comes a new series with Carbon Core Guard structure, which takes toughness to a new level. The case is made of fine resin that incorporates carbon fiber for light weight along with rigidity that is superior to that of resin. This material protects the internal module from shock-induced damage and deformation. The dual back cover protects the back surface against impact. Button structure shock resistance has been improved, which eliminates the need for external button guards.The face of the watch consists of a disk pointer and raised hour markers for a look of bold toughness. This new standard bearer of the G-SHOCK lineup combines a new shock resistant structure with urban outdoor styling that reflects its toughness.

This is truly a carefree watch. The dial is big and easy to read. The illumination is excellent. It can even be used for a night light for walking around the house after dark. The time is updated every day,so it is very accurate. It's solar cell keeps the battery charged. It is surprisingly light weight. It has all the features I want, plus many that I will seldom use but are nice to have. The only negative is a personal one, I don't like straps on wrist watches, so I replaced this one with an aftermarket bracelet.

I like the fact it not only looks good for casual and going out with its gold face dial, but it grabs the time every day via radio frequency so has great time keeping and the fact I never need worry about battery again. When it arrived it was on medium battery, probably down to being boxed a while, but I put it outside on the patio table in a mug so the face was facing the sun. It wasnt a boiling day and slight cloud cover but within 3 hours it was on high battery level. I took it inside and an hour later back to medium level, so I thought I'd leave it outside a little longer as I wanted a full battery before we go into winter and less sun. A full two weeks later and it's still on high battery and perfect time keeping. My only issue is the thickness of it, as I ride ... MoreI like the fact it not only looks good for casual and going out with its gold face dial, but it grabs the time every day via radio frequency so has great time keeping and the fact I never need worry about battery again.

My only issue is the thickness of it, as I ride a motorcycle and my jacket wont go over the watch, I tend to have to ride without it, which is a shame to be honest. Would I recommend? Yes but remember to take into consideration that a leather motorcycle jacket wont fit over it, and I wont be wearing it over the top of my leathers either. Otherwise, a fantastic worry free watch that should last decades and always have the right time.

The watch keeps perfectr time to the second. Dial is easy to read with analogue hands. Some people may consider the watch to be too big or bulky but it's ideal for me. I got mine second hand at half RRP. This style of G-Shock was first manufactured in 2017. Look at the serial number of the watch found on the back plate and the last character is a letter that indicates the watch's year of manufacture. From the last 4 characters you can calculate the exact date the watch was manufactured. Do your research. There are a multitude of websites pertaining to the G-Shock GAW-100B.

This watch is a great timepiece for the cost, its durable as well as stylish.Im impressed. I own omega,seiko, invictas, timex,Casio,and citizens and Id put this timepiece up against anyone of them as far as precision time keeping.Now its going to seem a little complicated at first reading the instructions, but there are ample utube videos covering every aspect of this watch and others operations.Its not really that hard,trust me if I can do it anyone can. Very comfortable for a larger body watch. Casio definitely hit a homerun with this model. I recommend the watch and my seller. Both superlative.
Works great. Only four stars because it takes too much time to study how to set up and operate the watch's features. Thankfully, it's user-friendly. You can tell time even if other features are not set properly.
I had a casio solar watch, an inexpensive one for many years and loved it but was showing years of abuse so I wanted to purchase another one. Unfortunately this was the only one I could find and so I got it. Received it and could not figure out how to set it so I contacted Casio and low and behold they were able to help me "Set a watch". I will say, I have had this one now for awhile and have fell in love with it. It even reset itself when the time change happened. Not sure what will have happen if Texas no longer is time changing, but we will see. If you like the look of the watch and is looking for one that basically takes care of itself with just a little sunlight I highly recommend this watch. The reason I did not give it 5 star was because the instructions were ... MoreI had a casio solar watch, an inexpensive one for many years and loved it but was showing years of abuse so I wanted to purchase another one.

My 1st g shock watch. Normally only buy manual watches for my collection. Made a exception to my rule and bought this one after seeing it someone. It’s great on my wrist, excellent time keeping as adjusts every day to atomic clock. Easy to set up. Solar battery means I won’t have to replace it. What more could you ask for in a quartz watch.As for the purchase of watch from first class watches. Thank you purchased on the Sunday and delivered on the Tuesday. Very happy
Love this watch! It's looks tough yet stylish. Would go well with casual or smart casual wear. I thought that the digits would be hard to read because of the negative display but was pleasantly surprised to see what it wasn't so: it is quite clear. It has got a batter power indicator, which tells you if the watch has got enough power (L,M,H - low, medium, high). When I got the watch, it had medium power (possibly because of being in a box for months) but after a few hours of being exposed to sunlight, it went up to high and has stayed high ever since. I leave it facing the window when I'm not wearing it (I don't think this is necessary though). Also, it will recharge with any light available, so yo don't have to worry about it not getting any charge. Great watch, ... MoreLove this watch! It's looks tough yet stylish.

I never owned a G-Shock before. Instructions are straightforward and easy to follow. set it up in 15 minutes. I'm on the total end of the east coast ~2500 miles away from Fort Collins where this atomic watch get its signal from, and still get L3 (highest) signal in some spot of my house. Battery left faced the light outside for couple hours (not directly in the sun) and it charged to full and still full, weeks later.
Nice looking analog-digital g-shock w/ tough solar, I ordered this online and pickup at walmart curbside. I was surprised when I got it because it didn't came with the usual box or tin can, it is just in a casio g-shock display stand with the manual and warranty booklet in it. Good thing the watch itself is in perfect brand new condition.
