Product Description

The Casio Pro-Trek PRW-51FC-1JF represents a sophisticated evolution within Casio’s high-altitude line, blending the classic, instant readability of analog dials with the technological capabilities of digital displays. Manufactured to the strictest quality standards in Japan and intended exclusively for the Japanese Domestic Market (JDM), this impressive 47.4 mm model is designed for those who demand a tactical exploration tool without sacrificing an elegant, urban aesthetic.

This model stands out for incorporating high-end watchmaking components: a sapphire crystal with an anti-reflective coating that guarantees absolute scratch resistance and a screw-down crown that optimizes the case’s water resistance.

Equipped with the Solar Caliber 5620, this watch is powered cleanly by any light source and provides instant readings of the environment thanks to its Triple Sensor system.
