Review: A quality watch - Bought as present...quality watches
Review: Casio made very good quality watches - Casio made very good quality watches. I have purchased the red colour version and have been very pleased with it since day one. The watch is very accurate and it also comes with a small amber LED light to see the time at night (I know some reviews said the LED is poor but my honest opinion is it does the job and you can see the time in darkness). The watch is totally water proof and cold weather proof. I have done a weather test myself by leaving it in a bucket overnight as well as leaving it inside my freezer for 24hr. The watch survive in both tests and I have attached photos for your reference. Very happy with the product and I would definitely recommend it to anyone who is looking for a sporty looking, strong and reliable watch.

### ⭐⭐⭐⭐⭐ An excellent G-Shock!
*by L***X on 23 October 2015*

Excellent G-Shock! The appearance is incredibly good, it screams "sporty" and "stylish" the dial looks like the speedometer on a Ferrari, if it didn't say "Casio" and "G-Shock" on it I would think it was a Ferrari brand watch. It is incredibly accurate and comfortable it gets a lot of attention and looks fantastic, the negative display can be a tiny bit hard to read at times but it's really not too bad and the light is good enough also to light up the hands. Another thing to note is that you can choose to either display the time or the date on the screens below the hands you cannot display both, this is a small issue as the hands will display the time regardless and if you change the time digitally? the hands will move on their own to adjust (Which looks so cool, trust me!) I could not recommend this watch enough! fantastic release from Casio!
