I own more expensive watches… this is my favorite for everyday wear. To say it’s a good watch for the price would be wrong, as it’s simply a good watch that happens to be extremely affordable. It’s not a Rolex or an Omega. It’s not even higher-end Citizen or Seiko, but that’s the point (in my opinion). I wouldn’t drive a Cadillac through the dirt, but I would drive a rugged Jeep, and that’s what you are buying. I love my higher-end watches and smartwatches, but they are not really applicable to my daily lifestyle. That said, I probably wouldn’t wear this watch to an important business meeting or formal event. The light works well in the dark, though it is a little difficult to see the digital elements. Setup was fairly easy. The watch is comfortable and keeps time well. The packaging threw me off at first, as I was expecting the classic packaging and tin box. At first I thought that I had received a replica until I inspected the watch and its functions. From what I understand, Casio changed their packaging to a more eco-friendly design. If such is true, I don’t really care about the box and if Casio wants to create a more eco-friendly brand, that’s fine with me. ... show more

    • Gran reloj todo terreno
Gran reloj, tamaño ideal (se tiende a pensar que estos relojes son muy grandes, cosa que no ocurre con este modelo). Buena combinación de colores

    • Best sport / work watch ever
This is the most durable watch I have found. I spend time on tractors and using all types of equipment and other watches would get scratched and looked like junk. I have another I have had 3 years and it looks great . I decided to get one with both hands white so I bought another. You will not be sorry if you choose this watch. ... show more

    • Don't expect a real alarm! Don't expect a real alarm!
Review Image by Mario D.
It's a good looking watch that keeps great time. The screens on the watch are small and hard to read in low light. The hands are fine but not the screens. It has illumination on the hands but must be charged with a flashlight or strong light source, but don't stay bright very long. The worst part is the alarm. Absolutely worthless. Even in a quiet place you can barely hear it. There is no volume control. Better looking than my Fitbit but not near as functional for most things. This does have stopwatch and world time if you need them. Basically a fashion statement with some functionality. Slightly disappointed overall, but looks cool and will probably keep it. More fun to shop for than use. Updated to 4 stars from 3 originally. This thing grows on you. It's cool 😎 ... show more

Bought this for my son-in-law. It’s awesome, he loves it and if it can last through him, it can last through anything! 🤣
