a great watch, takes a bit of getting used to, as the "search" button in the bottom right can be easily tapped, causing brief amounts of panic if misread.a very easy watch to learn and the strap is strong with a much stronger clasp than other models.

Great watch for bigger wrists

Stylish. Comfortable band that accommodates guys like me with larger wrists. Really cool illumination. Only con is you cant see the time even in broad daylight.

Great watch!

I had originally bought another G Shock from a local retailer and then I came across this one on ebay. I'm glad I returned the other one because this one is larger and much cooler looking. This watch has lots of features that I'll never even use, just need time, date and a light to see in the dark. I don't need to know the time in 100 cities around the world.

Great watch! Great look! Great value!

Comfortable, stylish, durable, practical. I needed a durable watch that looks nice and clearly shows me date, time, and utilized a stopwatch function. Great value!

Looks good, keeps time, but hard to see the dial
18 October 2015

I like it, but the dial is seriously difficult to read, even with the light on. Reading the timezones was hardly possible even with a big magnifying glass. Compass works well. Thermometer works if you take the watch off for long enough to cool to room temp. Otherwise you get a temperature that is something between your body heat and room temp. Fit and finish is really good. My bottom line is, buy it if you like the style and don't care too much about the details on the dial. Its a nice watch when you get it at the discounted prices on ebay.

Not very happy!
10 December 2019

I have an older g shock I have been wearing for a long time. It is tan, i referee basketball and umpire baseball, so I wanted one to blend in! The screen is very difficult to see unless you push the button for the light! Not very happy at all !

Overall a decent watch for the price
13 December 2021

I really like this watch but it is definitely on the big side. I knew that going in. Just like the negative display is hard to read in some light but I was aware of that when I purchased it. The light works great though. My biggest complaint is the alarm volume. If there is any noise around me, I can't hear it at all. It's super quiet. But it looks good and I'll just have to wear it when I don't need an alarm. You can see the size of it compared to my DW-6900BB-1DR. Overall, I'm pleased with it. Side note: to turn on the auto light feature, press and hold the light button until the "LT" icon comes up at the bottom of the screen. It's there but the instructions weren't clear on that.

Reason to go with a G Shock
10 November 2021

Awesome watch, comfy and stylish. Looks smart and sporty, good for any event! Great for work, built good and unbreakable and very light. Can not complain when buying a G Shock! & especially from shiels! Only jewellery store I will shop at.

The bigger the better!!
8 November 2021

I was looking for the largest oversized g-shock available. Once I purchased this one I found out there's one larger. That's the only reason why I didn't give 5 stars.
