FAQs

Q: Does this base include the hardware to bolt it to a flat surface?
A: No. Because these mount to such a wide variety of materials and applications, we don't know which fixings to supply. Your local hardware store, or the manufacturer of whatever you're mounting to, is usually the best guide on the right hardware.

Q: What size screws are needed for the holes on this ball plate?
A: The most common sizes are #8, #10, M4, and M5 screws. If you're pairing this with a RAM® holder, the holder comes with the hardware needed.

Can’t read numbers
Color: Gray/Gray/Digital
Numbers are too small to tread on a 44mm watch

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.

Good budget watch
Color: 2926 Silver Stainless Steel/Black Dial
Good watch for a budget, color is good. The pins holding the link together tend to wear out and fall out. Other than that it worked good.
