Casio ProTrek PRG-270B-1 Watch

Casio Men’s PRG-270B-1 Pro Trek Triple Sensor Multifunction Digital Sport Watch

The PRG270 is smaller than some of the older Protrek models, due to the smaller sensor, and they have moved the sensor location from the 10 o’clock to the 9 o’clock position. The triple sensor makes these watches sometimes called ABC watches as they have Altitude, Barometer & Compass readouts. The smaller design makes it easier to wear everyday, however the face is still relatively busy, with the case having front raised sections (at the 12, 3, 6 & 9) with indents. The sensor at the 9 o’clock position sits higher than the raised section at the 3 o’clock position. The crystal is recessed nicely as usual on Casio G-Shocks and Protreks.
Cons:
The Casio ProTrek PRG-270B-1 has not atomic timekeeping. It keeps accurate time, but you have to manually adjust Daylight Savings Time and changes in time zone.
