The watch looks great, keeps time great and is easy to setup. The reason I didn't give it five stars is the Night Light is useless. It's yellow which makes it difficult to see the hands and the digital read out.

If only you could read it in the dark.....

Reviewed in the United States on February 4, 2018

I would love to have given this watch a five star, but for one glaringly useless function, yep, the light. Why would they even design a light that has no use, it just soils the Casio name and I love me some Casio watches. This light is a side light that neither illuminates the hands or let's you read the digital display, useless unless you just want to flip your wrist and say, look, It has a light.
The remaining functions work as they should and the hands didn't need to be nudged into position, they were spot on.
Overall this is a good looking G-shock, I like the colors a lot and the band, (though it could have been a little longer) is extremely comfortable. I can wear this all day with no irritation, I even fell asleep with it on and that's unusual.
The hands don't have any coating on them to make them viable or glow in the dark and since the light is useless, you will have trouble seeing the time at night.
I had to drop two stars because of the light issue, it's that bad.

I eventually had to get my wife [the smart one in the family] to do all the settings

I started wearing G-SHOCK watches back in '83 or '84, big fan. that being said, it was so different in set up from the others I have owned, I eventually had to get my wife [the smart one in the family] to do all the settings. I still have not got past the learning curve on the stopwatch. i am afraid I will mess up the time and calendar functions that are now set just fine. now that is on me, an analog guy in a digital world. I just have not had any issues with any of the others I have owned.
I really like the looks, the band design is a bit wider and has two tangs on the buckle, with a nice offset in them that actually makes it easer to take off or put on.. the design seems a bit more comfy, prolly the wider band.

Love it! GSW fans will love it. Great watch to keep up with your kid.

Reviewed in the United States on December 19, 2016

My son loved it until he left it at his basketball game in the stands. He was devastated, needless to say no one turned it in... :( He is a huge GSW fan so this colorway was perfect for him. My other son has the same one just a different colorway, Broncos fan! It goes in the pool, shower, waterfall, snow, etc. wherever he goes it goes with him. It's a watch that keeps up with your kids; wouldn't suggest anything else for an active kiddo.
