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 →

The most distinctive specs of PRT-B50 *Editorial
— 100-meter water resistance (good for swimming but not for deep diving)
— ProTrek Connected App (you may manage all watch settings through your phone)
— Mobile link (Wireless linking using Bluetooth(R)) (for time sync with your phone data)
— Digital compass (measures and displays direction as one of 16 points)
— Step count (A built-in 3-axis acceleration sensor begins counting steps the moment you start to walk.)
— Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
— Barometer (measures the air pressures and displays tendencies in the weather)
— Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
— Low temperature resistant (stable operation of the watch is guaranteed even at a temperature of -20°C)
— Sunrise, sunset time display (Sunrise time and sunset time for specific date)

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.
