Deep, blazing red accents against striking, dark black give these watches, and the wrist that wears them, a kick of cool confidence.

Not my style, but a very good watch

Everything you can expect of a g-shock: sturdy and tough.

Pros:

- The red accents look great

- Tough

- Solar powered

Cons:

- It's actually pretty difficult to see the dial in dark environments (but it does have an LED)

- Sure it's tough, but the lens is a mineral crystal which is a scratch magnet

- This could be my individual experience, but it took a very long time to charge to "H" level. I'm talking about 10 hours in direct sunlight.

Really, in the end, watches are a subjective preference, and this one wasn't for me. However, if g-shock is your style, this watch is pretty good at the price point.

Unique dark tone design

Great watch, very light and fits smaller wrist well. Like the bluetooth feature as it makes adjusting the settings so much easier. But I wish the two watch hands are a little bit lighter in colour so as to be easier to read the time in a dark setting.

Simple layout is a winner

This is my second casioak but the one I'm wearing almost every day. Fast shipping was a big plus and I've had to email the team previously and they are great to work with.

What more could want.

Bluetooth technology.

Keeps your watch accurate.

I also like the time and place feature, that can keep track of places you’ve visited and time anywhere in the world.

It shows up on a map on your smartphone.
