Given that we live in an age where time is free and ubiquitous, I absolutely hate spending on a watch unless it holds meaning. And it does not need to cost a lot.But the moment I laid eyes on this it was love at first sight. The watch is a stunner but at the same time has the reassurance that all Gshocks have.It not thick at all and looks just right, even on a tuxedo. This might sound like an oxymoron because I’d hate seeing this on your wrist, but might as well just say it, this watch is a steal!

This watch looks so much better in the metal! This is the smaller version of the casioak and it does not disappoint! Wears very comfortably with its rubber strap and the gold and black tone attracts many compliments! Highly recommended!

GM-2100-1AER in silver. A sophisticated take on cassioak series that looks at home in more places than one.Bought for work to handle accidental scrapes during manual handling and to look good doing so; ended up wearing the watch outside of work as my daily with the exception of dressier occasions.Has a nice weight to it despite having a slightly slimmer build than the resin models so feels good.Looks good in proportion to my 18cm/7inch wrist, with a dial that’s easy to read. The back light feature is quite underwhelming and doesn’t last for very long but I can’t see myself needing that very often.The watch comes well packaged with plenty of padding and the box is aesthetically pleasing.

Yes, I'm a sucka. Like everyone else on hear I have countless G shock's.....but, I swore I'd never do it. Never ever buy a Casiok. Yet.....Here I am, deeply, completely in Love. It's GOLD. And utterly fabulous..
The Black and gold design is just so classy at the same time sporty maintaining the super ruggedness of G shock.The glass doesn't take any smudge. Even the silicon strap doesn't look like it is one. Looks more leathery. Once it goes , I am planning a leather strap.Overall very very happy. It's a G shock and NOT a G shock!!
A simple watch that does perfect what it is made for: showing the correct time.I love the weight of it. It is certainly a pleasure to wear a lighter watch sometimes compared to sportwatch such as Garmin or my exclusive watches which are quite heavy.With this design Casio has created a 2-in-1 watch, a casual watch with a sports look.Great watch!
Good looking watch that wears well on the wrist and while slim retains all of the robust features you'd expect from a G-Shock. Only slight downside is the negative digital display that can be hard to read on some occasions. Otherwise much to recommend this model.
Watch ordered and received in a matter of days. Great service......it even came with some added extras that I was not expecting.......HAIRS. It looks like the watch had been worn previously and the wearer had lost some of their wrist hair in the straps and bezel, at a guess it was a returned item re-shipped as the instruction manual was loose etc. Customer service when questioned were clueless to say the least. Aside from the hair the watch looks and feels fantastic.
I was happy with the watch once it was configured. Unfortunately there wasn’t an instructions manual included so I had to use the internet to figure out how to use it. Apart from that its a good watch.
it's a graduation gift, but I took it out of box and tried it on. it's really nice. and the finial isn't too flashy. if you're into gshocks it's definitely a winner.
