CASIO PROTREK TRIPLE SENSOR Watch Battery replaced, operation confirmed. The backlight also works perfectly. The asymmetrical body with a silver bezel and multi-tiered segments is cool. The sensors are also rugged and look great. The check pattern on the back of the strap is cute. It's rare to find a model with the bezel lettering still intact. This is a high-spec, multi-functional watch equipped with a thermometer, barometer, altimeter, compass, and more. The triple sensor was a top-of-the-line model at the time. There are signs of use, scuffs, and scratches, but the condition is not bad for a vintage item.
