Casio Pro Trek Watch PRW3500SYT-1D

From PRO TREK, the watch whose Triple Sensor capabilities keep you in close touch with the every changing natural world around you, comes a new collection of watches with easy-to-read STN LCDs.
This new model comes in a “blue moment” coloring motif that is designed to capture the mysterious natural blue of the horizon just before sunset. Blue moment coloring is reproduced by the use of basic black for case, band, and other major parts, along with blue accents on the bezel and for the ring around the face.
Black ion-plated (IP) titanium bands ensure both light weight and a great looking finish. The crystal is made of scratch-resistant sapphire glass, which provides plenty of protection during wear in the wild outdoors.
This watch also comes with Triple Sensor Version 3* capabilities, which enable greater measurement accuracy. Other features include MULTIBAND 6 time calibration signal reception, Tough Solar charging, a barometric pressure alarm that alerts you to sudden drops or rises in pressure, and much more.
This new model represents some totally new looks that are packed with popular PRO TREK features and functions.
