Casio ProTrek Tough Solar Triple Sensor PRG-550-1A4DR Watch

The PRO TREK says it all, yet, the one who is uninitiated, must know nothing else can be trusted outdoors as much as this. It’s easy-to-read, has ana-digi interface; is big and bright…but that’s the minimum you need to go through the measurement data easily. With the ‘Tough Solar’ power system, all you can expect is an uninterrupted, flawless operation. Technologically advanced and equipped with a lot of guts so that the wearer never chickens out before reaching a destination.
