Casio ProTrek PRG-650 Watches

Representative of the latest generation of ProTrek for travel. The external feature of the model can be called a concise and compact design – the case has become much thinner, and the placement of elements on the display has become more rational and convenient. Ana-DJ dial not only adds a bit of “classic” to the watch, but also visually separates the digital functionality from the analogue. The case is resistant to low temperatures – the manufacturer guarantees stable operation of the watch at temperatures up to -20 ° C. The watch has a triple sensor for measuring atmospheric pressure, air temperature and directions relative to magnetic north. Dual illumination Neon Illuminator illuminates not only analog but also digital zones. The strap is made of soft but durable silicone, with a luminescent coating – will glow in the dark. For quick access to watch functions, the Smart Access crown is provided.

Official Marketing Focus from Casio

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.
