Complying with the Military standard MIL-STD-810G along with its case and strap made of resin; dial window made of mineral crystal; and water resistance of 50 meters, the Casio Pro Trek WSD-F20-RGBAU is a remarkably durable smartwatch that can take tough hunting conditions for sure.

Casio’s noteworthy focus on ergonomics is very welcome when it comes to wearing comfort since the WSD-F20 is by most accounts a large watch. 57.7mm wide, 61.7mm tall, and 15.3mm thick never seemed too wearable – despite these being very hefty dimensions. More so, at just 92 grams the watch is relatively light. Watch Casio PRO TREK SMART WSD-F20 Quick Operation Manual.
