This Protrek watch from Casio offers incredible features for its price. In more detail it is light, good looking and comfortable, offering a plethora of features as compass, barometer, thermometer, altimeter, step counter, bluetooth connectivity, etc. Aa far as I know this is the first Protrek watch able to connect to a smartphone, which greatly facilitates the initial setup and customisation of the watch. It is not solar powered, but for me this is not a problem, since its battery lasts for two years. Overall a great watch for the money! Well done Casio!

This is a great watch. I own a lot of Casio G-Shocks but this is my first Pro Trek. Has loads of features for the price. Compass, barometer, thermometer, altimeter and last but not least, a step counter. Connecting it to your phone is easy and you can configure the watch the way you want. I for one removed the thermometer as you have to take it off your wrist and leave it for 20 minutes to get an accurate reading, which seems a bit pointless. A bit of info on the straps. They are quick release so can buy watch straps and fit what you like, another big plus. I got a Nato strap for mine. Nothing wrong with the strap it came with but I like to change things up. The lug/strap width is 23 mm, not 22 as some reviews report, 22 mm is too short. My Nato strap came with 23 ... MoreThis is a great watch. I own a lot of Casio G-Shocks but this is my first Pro Trek.

4sensor watch with tons of features. Lol price with what seems to be a fine fit and finish.
The watch arrived in perfect condition. Walmart had a great price. In addition to all of that, you can't go wrong with a Casio timepiece.
Was delivered a day earlier than said. Came in a nice wooden box, was packed well. Nice watch with good features, Bluetooth function connects easily and works fairly well.
Really nice, analog style makes it easy to see at a glance. The step feature is nice and it works as well as my pathfinders. The dark blue is very dark, and unobtrusive allowing you to get away with something other than black.
Excellent watch the only problem is the strap a little uncomfortable at the beginning but you get used to it don't forget to download the app for your watch you can don't much with it the watch works very well easy to fonction just connect to the app and it will reglagahe the watch automatically compass works well barometer and altimeter aswell but if you use the app on your telephone it will be more precise witch is normal but the watch does a good job on the whole the watch is very good I would have liked it to be very shock proof but it's not although I have hit it against a tree quite hard and it still works so it does have a ristance against shock but be a bit careful with it
love the blue tooth connect on a trip it ties the phone gps to the watch elavation an pics take. very cool
FITS WELL ON WRIST LIGHT WEIGHT G-SHOCK TOUGH.
