Ordered this a month ago and have work it almost everyday. This is a great everyday watch in my opinion. You can dress it up with a suit, dress it down with some jeans and a t shirt. I've even worn this with joggers and a sweater and it still works. So many ways to style. Highly recommended

I love my Casio Gshock, it’s not heavy had a great sleek design while maintaining a utilitarian and useable look. The size is perfect and is not huge like some others. It is massively adjustable and the finish on all areas is perfect. No problems!It’s an awesome watch especially for the price!!

This is a beautiful watch and I now wear it almost daily. I also have the resin version GA-2100, on the wrist ot feels slightly smaller, its strap is shorter and very slightly narrower than the GM-2100. The stainless steel case does develop tiny scratches from normal wear but you only see them by shining a torch on it up close

I bought this as a birthday gift to myself. I love it! Jared.com came through with great customer service. Shipping was super fast and secure. I mean really fast. The watch is ultra lightweight. I love the classy look from the metal clad case and the sporty look the rubber watch band provides. Feels great on my wrist. If you’re on the fence with this watch, do it. You won’t regret it. Glad I went to Jared!
Love this watch. This G Shock looks awesome with a new and unconventional design. It has all the functionality you need as a daily sports watch without the hassle of Bluetooth. I can keep it on all day at workplace where Smartwatches are not allowed due to security concerns.
In bright sunlight, this watch is stunning. But in less than perfect lighting it looks a lot duller and there can be real issues with legibility. Also the metal case can make the watch feel imbalanced/top heavy - although that’s probably more of a personal concern than an objective issue.In the right conditions, it’s a fine watch - in overcast Britain, we don’t get those conditions often enough.
I already have a few G-Shocks, including the gold version of this one. I must say that these new metal 'Casioaks' are fantastic value - adding such detail to the dial and markers, which really pop in the light. This chrome-effect version in particular looks great in the hand and on the wrist - looking even better in person than in the pics. If you like the look of this watch, just buy it, and see for yourself.
Before buying, had the full resin GA 2100, so knew it was a good watch anyway under the case.Fit & finish is excellent, the watch looks SO much better in person. A lot of reflections and polished steel looks so good. Also brushed steel on the dial is a great look to the opposing high polish.Black strap is very comfortable and hasn’t rubbed or dug in at all.Also still a fairly light watch, with a nice size.For the cost, I honestly haven’t seen anything coming close, even some £200+ don’t compare in my opinion. Great beater/daily, can’t recommend it enough.
I recently purchased a Casio G shock GM2100 aka Casio Oak. What a great buy, the watch is beautiful, slick design and does everything I want a watch to do. The fit is amazing, I have a slim wrist but the shape fits amazingly well around my wrist. Plus I got 10% of the sale price..bargain!Thank you so much FCW
Fantastic service from this company.Great looking watch (several people have mistaken it for an AP ceramic at a glance!) Not as big as on the wrist as the measurements suggest.Good quality and robust as always from G-Shock. Surprisingly comfortable for a rubber strap.If you need a watch for doing activities that would bash it around, this is the obvious choice. You don't mind doing things to it that you would shrink from doing to a more refined automatic.Don't be a snob, get a G-Shock. Every watch has a purpose and this watch fulfils what it was designed to do perfectly.
