Awesome watch, concern over the band.

ByAmazon Customeron October 6, 2016

Size: mens-standardVerified Purchase

Awesome watch! Fits great, looks great. A lot of reviews complain about the LED lighting. Yes, it's a little dim, but the purpose is to view the time, not guide airplanes for landing. Folks need to keep that in perspective.

There is one potential flaw I see with the design (hence the 4/5 stars). The piece of silicon that holds down the extra length of the band seems loose and will likely stretch out over time. I've already had to readjust the piece several times as it comes loose during the day. It would have been better if it was designed to latch through the adjusting holes in the band for a more secure fit.

Otherwise, I recommend this product.

A great buy!!!!

ByElizabeth Gallowayon August 29, 2017

Size: mens-standardVerified Purchase

Excellent watch!!!
I bought this watch for my 8th grader. My husband has one similar (which was much more expensive) and my son wanted one. It's an excellent buy. Great quality. Perfect size for a large boy or adult without looking too bulky. The features are everything you could want in a watch and very user friendly. No need for you tube videos to help you set it up or special mini tools to change the time.
My son absolutely loves it. I wish I found this before we spent almost double the price on my husbands watch.
You won't be disappointed with this purchase.

Very Clean and easy to program

ByDanon May 1, 2012

Size: mens-standardVerified Purchase

I do a lot of international travel, and work in a very active atmosphere. I wanted something rugged, simple, and not too flashy. Cue in this bad boy.
+Once you set your home time, crossing time zones has been easier. Just hold down the button and sellect a city in you timezone. Plus i can keep track of my home time zone making it easier to time my calls home. Also if you go back and forth between two timezones often you can just hold the buttons down and the will flip your home timezone automatically adjusting the hands to your current local time.

+Light works well, and you can program that to stay one which is pretty nifty.

-Only Con id say which isnt a big deal for me is the light. It light up the face just fine in a nice amber color but doesnt light the digital display which is slightly more recessed than the rest of the display. Again not a problem for me.

+Very light and comfortable as well. I had a smaller g-shock that I sold off while here and it was far heavier.

+You also get 5 0r 6 alarm clocks, one with a snooze.

+Lap times, Split times, and countdown timers which can chime an alarm at the end and be programmed to start the countdown again automatically. Good for boxing workouts id say.

+ Price: At the current amazon price you wont get much better quality or functionality. Doesnt have too big of a face or come off clunky either. Its right where it should be for an active person.

Hope this helps.

UPDATE******* 1 year

Same battery and still goin strong. The recessed glass in the casing has allowed this watch face to remain unscathed. Unlike my others.

Excellent seller, excellent watch

ByVermon February 23, 2015

Size: mens-standardVerified Purchase

First, the seller had a good price, delivered very quickly, and packaging was good. All original packaging just like you'd get from a Casio retailer. I'd have no problems ordering from this seller again.

The watch itself is Excellent. I've never liked G-Shock watch straps, so I replaced it with a Zulu strap. But that's just me.

Watch looks great. I really like the look of the blacked out face. Only issue is in low light conditions, the digital readouts are hard to see. Even with the light on. The watch light could be much brighter. But the hands show up nice and bright in most any light condition even without the light. So bottom line is you can easily tell time in low light, using any functions that require the digital readouts (setting alarms, checking the date) is not as easy, but doable.

This watch is technically bigger than other G-Shocks. But you'd never know it. Feels the same on my wrist as any other typical G-Shock.

Other than that, it's so far delivered the same quality and reliability that is typical of G-Shock. Which is to say excellent.

Perfect fit

ByStan C.on March 2, 2017

Size: mens-standardVerified Purchase

Fabulous product! This watch was strongly suggested by the military as one thing that recruits bring with them to basic training. The watch is known for being strong, shock absorbent, water resistant, has a back light which is convenient for night use, & a stop watch with speed indicator. The G-Shock watch offers both analog & digital options as well as shows the sate including the day of the week & the day (1st, 8th, 13th, etc...)
The watch band is made of silicon & does not grab or pull arm hairs as other watches tend to do. Setting the time/date is really easy as is running the stop watch. The watch comes in a strong aluminum case & also comes with directions as to how one can get the most out of their watch. I bought it for my son & he is really happy with it. After price checking brick & mortar stores as well as other online sites, this was by far, the best deal I found. There are several colors available but for the military, they specify black as the only option during training.

Perfect outdoorsy watch

ByBrian Hopperon December 31, 2016

Size: mens-standardVerified Purchase

I bought this watch to use for the gym and to bring surfing so I know what time it is when out on the water. I love this thing. It's sporty without being too bulky and goes fine with any casual outfit. I love that it's an affordable watch that's waterproof and practically "life proof". I've smacked it against things on accident and it doesn't even leave a scratch. I've had it for almost a month and it's working perfectly for all things outdoorsy: surfing, hiking, the beach, working out, etc. I'd definitely purchase this watch again if needed since it's such a great price.

My favorite G-Shock

ByJames F. Pelusoon June 10, 2014

Size: mens-standardVerified Purchase

I now own 12 G-Shocks, and this model is my favorite. That's really saying something, because two of my G-Shocks are Frogman models, and I love each and every one of the 12.

On this particular model, what I like the most is the fact that the hour and minute hands stand out so well. You can glance at your watch from even a bad angle, and immediately be able to tell the time. The digital readout is somewhat dim, but this to me is not a big deal.

So all in all, I'm truly delighted with this watch!
