Best Metal G-Shock yet. The MOD Vanquisher!!
27 March 2024U.Uche

originally posted on g-shock.co.uk

It’s truly amazing. This iteration of the full metal G-Shock truly dazzled, and impressed me to no end.

Better than any MOD.

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.

The gold is GOLD and wonderful with it, the finishing is fantastic and the contrast with the black face makes it easy reading too.. And the all works well as well!

I'm a collector of g shock watches they are everything you could ask for in a watch,style, reliability, and I would recommend GShock watches to everyone.

Lovely watch
2 December 2022

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 ‘expensive’.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.

An easy buy. Delivers exactly what it promises, collector’s joy: great looks, all the necessary features (tough solar, bluetooth), okay price. It might be a Casioak’s ”final form”, well — sapphire glass wouldn’t hurt. The bracelet looks great, but of course fits the price — a bit lightweight.However, again — an excellent balanced package. Only the MTG or MRG lines will beat it.
