## Description

Product Description

Review: Great watch for the price. - I adore this watch, feels lightweight, love the alarm and stopwatch feature and looks awesome. The watch hands have lume and it looks very nice and bright in the dark, the light on the watch is helpful for the dark evenings. I am looking to modify this watch and change a few things as my first custom watch, but just the green and black itself as standard looks really cool. Great value for money; I can highly recommend.
Review: A great looking slim G-Shock watch - I was looking for a casual watch to wear at the weekend. My current G-Shock and Pro-Trek watches are a bit too chunky to fit under a shirt sleeve easily. This one however with its "Carbon Core Guard" is slimmer and much more wearable. I love the looks of this watch. The contrast of the matt black face with the green hands and markers not only looks striking, but make it very readable. Low light visibility is also fine - the hands glow a vivid green in the dark and the LED light illuminates the face sufficiently and even the LCD display to some degree. It has the usual standard Casio features, including world time, alarms and stopwatch. Being shock proof and water resistant to 20 Bar, wearing the watch in less than ideal conditions is not a worry. The only minor criticism is that the buttons are a little hard to push, although these might free up with use. Overall a great looking and very usable Casio G-Shock. For me, it's a great balance of style and substance.

### ⭐⭐⭐⭐ Great watch
*by T***M on 6 February 2024*

Great watch, especially on offer Light Easy to read Had to have a look on line to set up but it was easy enough to find. Looks good, especially for a ‘beater’ watch. My only complaint was the delivery, I ordered from this seller as it was going to be delivered in time, but it just changed the delivery date when I checked the day before it was supposed to be delivered. So it should have been a week later but I’d did show up one day before the week was up. Shouldn’t be allowed to post a date and then just change it.
