The Tech on your Rist

[Interceptor]

At a Glance
Casio Pro Trek watches utilise Casio's unique Triple Sensor system to accurately measure temperature, barometric pressure and direction. This Pro Trek now also includes Wave Ceptor technology to ensure perfect timing to the second.

The PRW-1300T has Wave Ceptor technology which ensures perfect timing by automatically picking up a signal from radio transmitters in locations all over the world. It is multi-regional which allows you to switch between transmitters in UK, USA, Japan and most of mainland Europe to always have split second accuracy. But thats not all, the PRG-1300T is also solar powered, has 5 daily alarms, a countdown timer and much, much more.
