Our quick take
Casio Pro Trek WSD-F30 - 3.5 / 5
Chunky, outdoorsy looks
- 5ATM (50 metre) water resistance MIL-STD-810 durability
Two displays is better than one?
- 1.2-inch round dual-layer display 390 x 390 colour OLED panel Monochrome digital LCD
The great outdoors
- Pressure/altitude sensor GPS + GLONASS and QZSS satellite navigation Compass, gyroscope and accelerometer
Battery life
- 1.5 days normal use Multi timepiece mode - up to 30 days
To recap
Casio’s third-gen dual-screen outdoors watch caters for a specific market well, but its dual-screen USP is no longer unique, while strong competition and lack of heart-rate sensor limit its overall appeal.
