Casio Protrek Triple Sensor PRG-130T-7VDR Tide Graph Tough Solar Titanium WatchFeatures:PRG-130 PROTREK outdoor watches with built-in compass, barometer, altimeter, and thermometer functions, with a tide graph and 200m water resistance added just for ocean lovers.
The PROTREK series of outdoor watches make the most of Casio's cutting-edge sensor technology to measure and display all sorts of natural data. The series is extremely popular not only with people who enjoy serious mountain climbing, but also with leisure-seekers such as those who like trekking and car camping.
In addition to their triple sensors for the measurement of compass bearing, atmospheric pressure/altitude and temperature, the PRG-130 watches introduced today are also equipped with a tide graph function and 200m water resistance, which are very handy for use on any body of water.
The PRG-130 watches come with a wide variety of other functions, as well. The moon data function displays the lunar date and the phase of the moon, and the timer function can be used, for instance, to time yacht race stages. The auto EL light illuminates when you lift your arm to look at the watch. The Tough Solar high-capacity solar-charging system, which generates power even in the low light of a fluorescent lamp, is another outstanding feature.
The watches incorporate a wide-viewing angle LCD, which make sure the data display is highly visible. The large metal function buttons on the side are designed for ease of operation even with gloved fingers. They are also treated with a grey ion plating finish that resists corrosion and abrasion, and a urethane surround helps make sure they do not get pressed accidentally. The register ring used with the compass function is knurled and inscribed with all compass directions, further enhancing functionality.
