The PRX-8000T is the new flagship model in the “MANASLU” series of PRO TREK watches developed with the input of professional climber. This watch has a high-contrast design for maximum readability in unforgiving alpine conditions as high as 8,000 meters above sea level. The watch features bold white index marks and large hour and minute hands made from carbon fiber, which make a clear contrast against the black watch face and relatively inconspicuous logos and city codes. The large index mark at 12 o’clock is distinguished by a special shape and further highlighted by an arrow etched into the top of the case.

The PRX-8000T is the first PRO TREK “MANASLU” watch to feature the latest Triple Sensor Ver. 3 technology from Casio, which determines compass bearing, barometric pressure/altitude, and temperature with high precision. It is also equipped with an atmospheric pressure tendency alarm that notifies the wearer of sudden swings in atmospheric pressure, and comes with Multi-Band 6 technology for receiving time-calibration signals transmitted from six stations around the world. The bezel, buttons, and crown have a wear-resistant diamond-like carbon (DLC) coating and the face features scratch-resistant sapphire crystal, for a highly functional and rugged design.
