The Casio Protrek Duo Rotary Bezel PRJB001B-2D is the lightest PRO TREK watch to date, designed for long trails and ultralight hikes.
Features the first rotary guard bezel in the PRO TREK line.
Rotating bezel allows switching between two styles: an angular design covering buttons for everyday wear, and a rounder look uncovering buttons for easy access during outdoor activities.
Bezel protects buttons from accidental presses when in the angular position.
