It’s elemental Sherlock. Everyone should be running at least one Casio ProTrek watch in their collection. These ABC, pure digital timepieces are super legible, 200M waterproof, lightweight, accurate, solar powered, self-synching, intuitive, and come in amazing colors (see below). This current Casio ProTrek with its 3rd Generation Sensors is smaller than it’s predecessor the Pathfinder and more preferred. Value is high for the enjoyment and functionality achieved. POUs extend to everywhere.
