Review: G-shock, Ga-2100, great watch, v happy - I got the ga-2100, very happy with it. Nice compact watch, looks great. great quality as expected, was easy to set the time and work out the functions, gshock is a great brand, long lasting and sturdy. I will be using for work purposes and leisure, great for all weathers. Nice light feature, not to flashy. Fits nice on the wrist. And comes at a great price. Speedy delivery.
Review: G Shock watches are great - I bought this watch to replace another G Shock which I’d for well over 20 years, I smashed the casing beyond repair when I caught it on a door frame. Before that I had a G Shock that was stolen when I took it off a laid it beside me in an Alpine mountain hut. Throughout the years I had that 2nd watch it had some serious knocks that would have seen off many other watches. I’m delighted with my new G Shock and trust that it gives me the service of its predecessors. G Shock watches are just great for anyone who leads an active life and are great value for money, why pay our big money for an Omega or Rolex when a G Shock gives you function over fashion.
