Pro Trek Watch PRT-B50-1ER

The Watch
Technology meets practicality in this connected Pro Trek watch. On top of its many built-in features, it comes equipped with Bluetooth connectivity to seamlessly pair with your smartphone. Built tough, the watch features a 50.8mm resin case - wide and comfortable for optimal dial visibility. The multifunction dial combines both analog and digital displays, protected by scratch-resistant mineral glass. Multiple pushers on either side of the case let you navigate and adjust all functions with ease. On the back, a 4-screw caseback ensures a solid water resistance of 10 ATM.

The Dial
Casio's top priority with this model is functionality, and it shows. The dial features both analog and digital displays working in harmony. The hour indices are rendered as large, luminous Arabic numerals for effortless readability, complemented by a precise minute track around the perimeter. All functions are clearly labeled around the dial, including the full 360° compass scale. At the center, three hands command attention: the hour and minute hands are bold and arrow-shaped with luminescent tips for easy time-reading in any light, while the slim seconds hand adds a touch of refinement with its red-tipped point. In the lower portion of the dial, a large digital window displays the day, date, and additional function data. The Casio Pro Trek signature sits just below the 12 o'clock index.

The Movement
Inside this Pro Trek watch beats a quartz movement. Like the case, the caliber powering this watch is Japanese-made - a hallmark of reliability and quality - driving every function on this feature-packed dial.

The Strap
Built to handle anything, this Pro Trek watch sports an ultra-rugged resin strap to match its equally tough case. Black in color and virtually indestructible, it's the perfect companion for every adventure. The clasp is a silver-tone stainless steel pin buckle.

Water Resistance
This model offers water resistance of 10 atmospheres, or 100 meters - it's a genuinely water-resistant watch. With its sporty character, it's ready to follow you into any aquatic adventure. From puddles to the pool, this timepiece handles swims without complaint. Showering, bathing, and lap swimming are no problem at all. That said, our Ocarat watch experts want you to know that while this model is water-resistant, it is not designed for diving (professional or otherwise) and should be kept away from high-pressure cleaning equipment. We also recommend avoiding use of the crown or pushers while the watch is submerged.
