The Ultimate Guide to All PROTREKs — composed by Experts
Introducing new night safari concept models for the lineup of Triple Sensor Version 3 PRO TREK models.
The colors and designs of these three new models all were specially selected for the night time outdoor scene.
The outside of the bands and the faces of all three models are black. The designs of these models are stylish and subdued, without sacrificing the readability required during night time activities.
The PRG-650/650Y models come with DURA-SOFT bands that incorporate silicon materials that improve durability. The inside of the band is luminescent, so it emits a faint glow during night activities.
Function-wise, all three models are equipped with Neon Illuminator to provide easy reading of the time and function modes, even in the dark. Other basic functions include Triple Sensor (bearing, altitude/barometric pressure, temperature), one-touch measurement button, Tough Solar, and more. Movable lug components add to a better fit and more comfort.
Everything about these models is designed and engineered to create functions and designs for night time outdoor activities.

Year of first release: 2017
Nominations: best design, best functions
The most distinctive specs:
– 100-meter water resistance (good for swimming but not for deep diving)
– Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
– Low temperature resistant (stable operation of the watch is guaranteed even at a temperature of -20°C)
– Digital compass (measures and displays direction as one of 16 points)
– 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)
– Double LED light (LED light for the face and LED backlight for the digital display)
– Smart Access (the system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown)
– Luminescent band and hour markers
