Rated 4 out of 5 by from Seems Like It'll be a Great Watch! So first things first. I purchased this watch in black the first day it was available from REI. For some reason, it stopped taking a charge. I reached out to Casio Support a number of times, but they could not help fix the problem. So, as I bought it from REI online, I took it back to my local store. As always, REI took it back without any problem at all AND was able to order me an orange watch from the store. An orange watch came to my door a few days later as promised. I don't see the orange watch offered on the REI Website so I can't explain why I was able to order it at the store! Nonetheless, I like the orange look better. I've never owned a smart watch before and wanted this one for outdoor activities. I've owned lots of Casio watches and like them a lot. This is a nice looking watch. The tools are all pre-loaded and seem to work well. There are some pre-loaded apps, but many more offered through Android Wear. Here's the rub though, in order to maximize the use of the apps from Android Wear, you have to have your watch connected to your phone. So for example, I need my phone with me when I mountain bike to use the mountain bike app I downloaded. I need the phone with me to use my weather app, etc. I think this is common to all smart watches, but I wasn't totally prepared for this and I'm removing one star from my rating as a result. Otherwise, great looking watch. You can really customize easily using your phone etc. As others have mentioned, you need an Android phone to make maximum use of the watch and its capabilities (i.e it is Android Wear and not Apple!). I have a Samsung s6 and everything works smoothly. One thing that is neat is that watch will alert me when phone rings or I get a text etc. You can respond to texts with your voice and the microphone on the watch. This watch is big! It is lightweight and reasonably comfortable. But, you get a very easy to read face with a nice touch screen. Dual layer is a clever function. It dramatically improves battery life. I can't tell you how long battery will last, but I bet you'll get about a day if you keep in full color mode.

Rated 3 out of 5 by from Want to love it I really want to love this watch. I've always been a fan of Casio Pathfinder watches due to their functionality and their ruggedness. With that being said, I received this as a gift from my wife. She did not read the details. The watch gets a good feed of information from the phone it is paired to. If you have an Iphone, you are out of luck for full functionality. You can't do much more than use the native apps and change watch faces. The watch is android based and you need an android phone to really utilize it. Pros - seems very well built. also seems to be fairly accurate on the readings, compared to a buddy's Garmin watch. Easy to set up. I didn't even have to open the directions to get it working. Pretty easy to use with the functions it has. You get notifications from your phone, but can't respond to them on the watch. Cons - Need to have an android phone. Seems to have some pairing issues. Has to be plugged in to a power source to pair to a new device. Battery does not last long if you are actually out hiking with it. No internal GPS. Has to be paired to the phone to make it work. Why have a lightweight watch that requires a heavy phone to work if you are a backpacker? REI only carries this in black. All in all, I do like this watch, but will probably return it for a better device that has better functionality for my lifestyle. I've actually considered giving up my Iphone for an android, but I have 8 months left on my contract.

So if this watch gets its GPS signal via your android phone, doesn't that mean it's useless in an area where there's no cell service?

Asked by: campchick
No. It's possible to be in an area that gets GPS without cell service. All will depend upon the phone one has. Accuracy will most likely be affected as phones often use more than just GPS signals (eg wifi, cell tower location) to improve their ability to determine location.
