## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Watch.
*by K***I on June 24, 2025*

Looks Great, even though the actual silver could be way better if it was actually metal. Not as large as I expected. Great Seller.

### ⭐⭐⭐⭐⭐ Tough watch
*by D***. on May 22, 2025*

This is your classic no real frills, tough watch. It's lightweight and comfortable to wear and even though it's a larger size, you kind of forget that you have it on your wrist. It's definitely what you want if you're rough on watches.

### ⭐⭐⭐⭐⭐ G-Shock quality and ruggedness
*by D***S on April 26, 2025*

I have several G-Shock watches and this is my favorite. I got it a while ago on a deal. It was new, but did not come in a watch box or anything. I frequently get compliments on it and it is rugged like a G-Shock should be.
