Awesome watch brought for the wife to add to my watch collection

The watch colour is copper/bronze rather than rose gold, giving it a stunning visual pleasure on how the light plays with the indices, hands, sub-dial and bracelet. This is a welcome edition to the metal range with all the regular G-Shock goodies: Bluetooth, touch solar, 20 bar water resistant, etc. Quality Casio fit and finish, bring on the titanium range.

Have recently purchased 2 g shocks as an impulse buy, for the money I feel like itâs so worth it as they are pleasant looking watches and stylish fashion accessories that are also very tough and durable, and I could buy 80 of these for the price of a big name brand similar looking! Really puts things in perspective and Iâm not scared to getting mugged or attacked. Quality wise and functions I really canât fair either but the all metal g shock is better and solid. I have a collection of 12 watches ranging from 100 to 6000 pounds and enjoy wearing these more as everyday watches.
Lovely looking watch, though it does look like a tarnished copper colour, when it could be more of a rose gold, to make it appear more âexpensiveâ.The functionality it great, and having the link to your smart phone makes setting the time very easy.I received my purchase within 3 days of ordering online. Great, smooth service from Casio.
Mineral glass? no multiband 6? No thanks. Make the price ÂŁ199.99 and maybe. And Steven Bartlett? never heard of him or his company, hardly makes this a collecticable in any way.
An easy buy. Delivers exactly what it promises, collectorâs joy: great looks, all the necessary features (tough solar, bluetooth), okay price. It might be a Casioakâs âfinal formâ, well â sapphire glass wouldnât hurt. The bracelet looks great, but of course fits the price â a bit lightweight.However, again â an excellent balanced package. Only the MTG or MRG lines will beat it.
Great watch, will purchase another
So far I like it . Itâs good quality.
Absolutely stunning colour I love it, definitely more of a coppery bronze but it compliments my beloved gold B5000D perfectly. It looks so good under different lighting conditions and really pops in sunlight.The build quality is excellent and it has such a nice weight and feel to it, same as my gold B5000 which i've worn daily for almost 4 years and is admittedly still my favourite, but only by a fraction.I'm a huge fan of these full metals.
