I absolutely love these watches! They are built like a tank. They can take a lot of abuse and still keep great time. I originally was going to buy just one to replace my old watch. Ended up buying several of them. Great gifts. The watches are beautiful and elegant, and I feel like a thief when I buy them because the price is so low I think its a typo. I have gotten several compliments on them when I wear them. I have busted up concrete and cleared heavy terrain ,cleaning areas out, wipe then off and they look Like I just took them out of the box. The only thing, and it's not a big deal to me.But the glow in the dark arms don't last long. They even give you the tool to adjust the wristband. Who does that🤣 The Quality of these watches are phenomenal BUY ONE! You won't be disappointed.

Very handsome well-made watch comfortable to wear.

Color: 5885 Siver Stainless Steel/Blue Dial

Very handsome watch. At first glance, it resembles a Rolex. In two days I’ve gotten multiple compliments. Several have asked if it was a Rolex. That’s hardly what I was going for, in fact I had to look up Rolex watches to see what was being referenced. The watch fits very comfortably.
