Enjoy our ProTrek PRT-B50 Watch Review

A good start, gentlemen. I’m delighted with this “smart” approach: when we can enjoy traditional analog beauty and still match the 21st-century technologies. Yes, there are still many smartphone connections, no “low-energy” GPS, but I am sure a new ProTrek generation will soon attract other people’s eyes. Read Full Review →

Official Marketing Focus from Casio

PRO TREK’s ability to combine the best that technology has to offer and innovative designs has made it the timepiece of choice for climbers, hikers, campers, and other outdoor enthusiasts. Now the PRT-B50 Series adds Bluetooth® capabilities that enable data communication with a smartphone running the PRO TREK Connected app, for the ultimate in ease of use.
The Quad Sensor system uses compact sensors that make it possible to pack compass, altitude/barometer, and temperature measurements, along with an accelerometer that keeps track of your step count, into a compact configuration. Calorie calculations use both step count and altitude information to take upgrades and downgrades into consideration, and calories burned values are recorded by the app. The app automatically records altitude data measured by the watch and route information acquired by a smartphone’s GPS, and you can manually plot altitude points along your route using a Route Log feature.
