Delivery is great. It's a genuine watch. Step tracking is working fine. Users need to install an app to use the feature. The watch box is not good.Overall it's a really good watch and it's not as bulky as other G shock watches. Strap quality is good.

Functional and good looking

Took me some time to figure out how everythings works, big difference from a ”normal” smartwatch to use.But when you learn how it works, it’s just great. Perfect for training sessions and in the everyday life. Maybe not something you wear to a suit, but really good looking.

Great purchase

Great service watch arrived faster than expected and was everything I hoped it would be. I ordered a Mudmaster as I am a landscape gardener and need a watch that can cope with the demands and conditions of my job. So far it is absolutely perfect and the added bonus is that it looks good as well. The Bluetooth functionality meant that the watch was very easy to set up. I think at a later date I may go for a solar powered version as long as it is as rugged as the battery powered version. Full marks G-SHOCK

Not exactly what I expected but nice watch
14 January 2024

I find it a bit big but not too uncomfortable to wear. The light makes it hard to see what the time is. There's not enough contrast between the background and the hands of the watch. Overall, it's a nice piece and the functions work good.

Top quality, rugged and a great look
14 September 2022

I wasn't sure about wearing a "white" watch. Especially afterLabor Day. But the contrasting black watch face and shineynumerals are a great contrast. It's a typical size dive watch,good weight but not over-powering on your wrist. This isdefinitely a top down, wind in your face, summer cruizin stylethat would finish any sporty look.
