Fairly low quality watch. Exterior is not bad, more of a ladies watch....offered it to my gf but the face was a little large. Looked more manly via pictures. Looks unfinished. I'd send it back but it would just cost me moneyCheap-ish type of watch....

This model is a bit different from the conventional Gshocks. It looks apart and feels very nice on the wrist. It has a good readability and the bright green offers a beautiful contrast—only 4 stars because of the metal loops, which are pretty loose.
Lovely lightweight watch. Large face but not bulky. Really nice
I have always had my eye on the G-shock range, but seeing how I belong to the itsy-bitsy wrist society I have always felt the watches were rather big for my small wrist. I was delighted to see this new model, and I have to commend Casio, it's just fabulous. The description says the color of the watch is "pale pink", however, it is actually a very light creamy color with gold colored details on the dial that gives it a beautiful finish. There's no need to worry about pushing any of the buttons by accident, all is very secure. The dial is beautiful, and the indicator that tells you what day of the week it is, is really clear. I have been mostly using the stopwatch and it is really easy to work. Love it, love it, love it!
Stylish, great time keeper. A little fiddly to change time. Apart from that all good
Lovely watch really like it. The strap is the o my problem for me seems cheap and hard not very comfortable
Bought for my sonHe went off to Australia travellingHe loves it
Excellent watch ~ it's not pink, more like a cream warm sunshine shade. Very clear face indeed, nice clean cut and simple. I love the analog day of the week feature. The face has a 3D effect which makes it unique and interesting and the markers are brilliant in low light because they are the only shiny part of the watch and therefore they clearly reflect low light very nicely so the face is clear even then. The hands are luminous and if you charge the watch under a strong light for even 30 seconds they glow brightly. The LED double light [backlit digital light & dial light] are extremely bright. Nowhere in the manual or anywhere else does it mention that actually the light illuminates for a full 5 seconds when you are running stopwatch or countdown mode. Very ...

The first thing that struck me upon opening it is that it seems smaller than the videos I watched about it, which was great. The thickness of 11mm is excellent. I found it pretty straightforward to set up. The hourly signal is subtle and quiet but very useful to me. Good solid build and very light at 41grams. Minute hand moves every 20 seconds. Highly recommend!
