    • Feature rich. Easy to use. Dead on accurate.
If the features of this watch are what you are looking for, this is your watch. I am happier with it than I thought I’d be.

    • Love this watch, I have two
This watch does everything that it’s showing to do, I have the pink version that came from Japan that was $700 it’s the same watch as this one and I got this one for work, this watch I believe I paid $320 for plus tax and it works flawlessly It has a barometer, compass, altimeter, it has everything and everything works plus the nice part is it is solar powered and you don’t need to replace batteries they’ll last for probably 10 years if you take care of it and then those batteries at that point can still be replaced but after 10 years you might want another one I know $300 for a watch sounds like a lot of money but it’s so much more than just a time piece and they’re rugged as hell I’ve used these watches from G-Shock for decades and they just keep getting better and better, the reason the pink one was so expensive is because it was a limited edition from Japan and they offered those in a couple of rare colors and I just liked the dark pink and so my wife bought it for my birthday and surprised me but for work I prefer black The case and the band are black but it’s not a shiny black it’s a flat black, the face is black behind the crystal and the numbers are dark in the data but you can still read them easily, I like the automatic light where you just hold the light button down for three seconds and then it puts it in auto mode and hold it another three seconds and it turns it back to manual mode sometimes at night it’s nice to have it on automatic because when you rotate your wrist forward and then rotate it back where you can read the time the light comes on for one second or three seconds which you can adjust as well this watch is amazing nobody makes a heavy duty watch better than Casio ... show more

    • Excellent watch. Hard to update with Atomic Time server.
Watch arrived Feb 2024 1.5 minutes fast. It showed it last synced with Atomic Server June 2023 so that's expected as it comes in a metal box. It's supposed to update nightly and sync with the server but it requires a strong signal. Leaving it in a window overnight didn't work. I physically had to go outside and face Denver and do a manual sync. 5 minutes with a steady strong signal (L3) did the trick. It's a little hard to read since it's blacked out, but I love the look and size of the watch since I have large wrists/hands. I especially like this because my work doesn't allow bluetooth devices and this is better than a simple Timex. Extremely high quality. I'd say keep an eye on it before buying. I got it for $240 and a week later it's selling for $217. ... show more

    • True Survivor
Got this as a gift for our son, who was in ROTC and is now active duty. It has survived unknown trauma in both, but guaranteed he doesn't baby it. A couple of years later, he still loves it and is still wearing it daily. He says the functions are pretty overwhelming, but likely they will come in handy the more he gets into his duties. It has thrived living in diverse climates, from hot and humid to freezing cold and dry, mud, swimming, and dust. One thing we did learn, trekking through FL swamps- remove it before using bug spray. The band got slightly pitted from that, being plastic, but according to the wearer it just adds to the "lived-in" look, and its functioning was not a bit affected. It sometimes didn't immediately update the time as it should (tested by crossing many time zones), but apparently it's simple to update manually. Would definitely recommend as gift for anyone with military inclinations, or anyone who loves a watch that does a lot of stuff and is tough. ... show more
