Fabulous watch idf you talk about design , material, or built quality. No regret purchasing it. Amazing addition to the collection.
Nice lightweight analogue watch.Sits really well on the wrist and is super comfortable.Doesn't have all the bells and whistles but for me still really nice to look at.
Fantastic watch for the price, have several watches costing much more, but won't be buying any more without checking gshock watches. Looks great on the wrist and can't get over all the functions. Great product casio, if you shop around you can get it 50 quid cheaper.
Ordered this watch as it looked great. I personally found the instructions so poor I couldn’t even set the date.I’m sure it will be great if you can get it set up.
Really nice release - crisp finishing and details for the price, very comfortable on wrist, and wears a little smaller than the size suggests. Works well with the app. Only real gripe is the wheel power meter makes no sense, and it doesn't have hourly beep.
A beautiful G-Shock with supreme Read-ability and useful functions. The Tough Solar sold it for me as I always look out for G-Shocks powered by light. A great watch all in all and looks great. The hands are some of the best looking on an analogue. Love it. Thanks.
Excellent service from this company & over £60 cheaper than other retailers selling the same G shock. Would highly recommend Francis & Gayle. This is the second quality G shock I have purchased from them. 👍
