Lovely watch
I love G Shocks. In this case I love the brilliance of the colour, too. G Shocks are iconic, virtually unbreakable & keep good time. What else could you need?

Quality watch
Nice, good, solid, light watch. As always G-SHOCK is packed with everything you need on daily basis. And the colour, just perfect.

Arrived quickly. Good price.
It is a present and so has not been worn yet.

Great Look, Feel & Quality But Setting the Time Is Frustrating
I really like this watch — and for the most part, it feels like a solid daily companion. From the moment I put it on, the fit and comfort stood out. The strap feels nice on the wrist, the weight is balanced (not too heavy or too light), and it sits well without sliding around. The build quality feels good for the price, and the colour looks stylish and modern — definitely something I enjoy wearing every day. Style & Feel: • 👍 Comfortable fit — easy to wear for long periods • 🪶 Perfect weight — feels substantial but not bulky • 🎨 Nice colour — classy and versatile • 💪 Good build quality — feels sturdy and well-made Visually and physically, it ticks almost all the boxes. The combination of analog and digital displays looks great and gives it a sporty yet elegant edge. However, there’s one area where it’s been a bit of a headache… setting the time. Time Setting — The Frustration: Even after following video guides and instructions carefully, I couldn’t get both the analog and digital times aligned correctly. I would set one, then the other would be off — and no matter what I tried, I couldn’t sync them properly. It was very frustrating, especially since the watch otherwise felt great in every other aspect. I ended up spending more time trying to set the time than actually enjoying the watch — and while many people might get it right, I found the process overly complicated and unclear. Good parts: • 🕰️ Looks great on wrist • 👌 Comfortable all day • 💎 Quality feel for the price • 📏 Perfect weight & fit • 🎨 Stylish, modern colour One real drawback: • ⚠️ Time setting is confusing — analog/digital doesn’t sync easily even with guides Overall: This is a very nice watch with a solid feel, great comfort, and stylish look — but the time setting process was unexpectedly difficult. If you’re comfortable with fiddling and tech-savvy, you might figure it out faster than I did. For everyone else, this part could be a real pain point. I still enjoy wearing it and think it’s worth the buy — just be prepared to spend some time on the setup. Readability is also good.
