A great and versatile everyday watch
2 March 2023Jair

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

A great looker

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!

Awesome watch

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!!

Beautiful metal covered G-shock
5 February 2023

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

Classy & Sporty - Best of Both Worlds
8 January 2022

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!

GM-2100-1AER silver

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.

Looks amazing but almost illegible
5 January 2022

Casio need to really do something with the legibility of these. You are half guessing the time with the hands and the LCD display is useless. This is not just this one but pretty much all of the Casioak range. Disappointed coming from the 5600 squares. May have similar functionality to the squares but almost no use whatsoever. The design is classic, sizing is good and cosmetically everything works on this watch you just can't read it! It needs to have some more contrast on the dial eg the hour markers and hands. And especially on the LCD display.

Perfect Light Travel Companion
12 November 2022

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!

20 December 2022

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.
