Leather Band

Imitation leather band

100-meter water resistance

The "BAR" value indicates the number of atmospheres to which water resistance is ensured. 10 BAR means water resistance to 10 atmospheres. Watches marked "100m" have the same water resistance as 10 BAR watches.

Smart Access

This ground-breaking CASIO system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown.

Tough Solar

CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power.

Features

This new caving-themed timepiece is the latest models from PRO TREK, the outdoor watch that is constantly incorporating the latest in technology and design innovations.
This model starts with the jet black of underground darkness, which is accented by orange and yellow colors that are often used in caving suit designs. The hour markers and bezel markings are embedded with luminescent material for easy reading in the dark. This same material is used for the luminescent center stripe of the PRG-650YL model’s leather band, which makes it highly visible even under the illumination from a headlight. The stainless steel band ring has an ion-plated (IP) finish that matches the black image of this watch and also provides a higher level of durability.
Advanced functions include Triple Sensor (bearing, altitude/barometric pressure, temperature), hand shift, and more.
