HISTORY

For everyone who loves mountain-climbing

PRO TREK got its start in 1995 as a brand focused on adapting original sensing technologies from Casio for outdoor use. The first PRO TREK watch, the DPX-500, featured Triple Sensor technology, offering measurements of compass bearing, barometric pressure, altitude, and temperature.

A passion for operability from the user's perspective

In 2000, significant progress was made in establishing PRO TREK watches as an essential and authentic part of users' outdoor gear. Embracing the idea that effective tools must be developed with real-world experience, mountain-climbing experts were invited as brand ambassadors to provide input based on their professional knowledge.

Delivering long-lasting, reliable, advanced performance

While features like Triple Sensor and a large LCD offered excellent functionality, they also consumed significant power, raising concerns about battery replacement and maintenance, such as a need for periodic water-resistance tests. To address this, the PRG-50 introduced the Tough Solar power system, harnessing sunlight for reliable energy during outdoor activities.

Accurate timekeeping with further reliability and convenience

Casio introduced its first radio-controlled watch in 1995, and the integration of this feature into a PRO TREK watch had long been anticipated. By using standard time radio waves for automatic time calibration, this feature ensures precise timekeeping — a key concern in mountain climbing — and eliminates the need for manual adjustments, offering greater convenience for outdoor activities.

Achieving a fit that never impedes wrist movement

A meeting with mountaineer Hirotaka Takeuchi after the development of the PRW-1000 marked a key turning point in the evolution of PRO TREK. Takeuchi reported that, during a field test in the Himalayas, he chose not to wear the watch because it felt too bulky on his wrist.

A line with sights set on the highest pinnacles

In 2009, the flagship MANASLU line of PRO TREK timepieces debuted, named after the 8,000-meter Himalayan peak summited by brand ambassador Hirotaka Takeuchi. Developing the first MANASLU watch brought a new challenge: reintroducing the dual-layer LCD that had been removed to achieve a slimmer design in previous models.

Adding a new watch hand especially for outdoor gear

The analog display in the PRW-5000, released in 2010, allowed users to quickly grasp both elapsed and remaining time through the position of the watch hands. Building on the potential of the analog display, Casio introduced the PRX-7000T, a fully analog display watch that not only showed the time but also indicated sensor data, including compass bearings, making it a versatile tool for outdoor adventurers.

Delivering further improvements to measurement accuracy

Responding to demands from expert mountain climbers like brand ambassador Hirotaka Takeuchi, as well as rescue teams working in harsh mountain environments, the PRO TREK development team focused on delivering even greater measurement accuracy.

In pursuit of the ultimate in functional beauty

Under the supervision of Hirotaka Takeuchi, the first Japanese climber to summit all 14 of the world's mountains over 8,000 meters, a new timepiece with enhanced technical specs and overall quality was introduced to the MANASLU line, now firmly established as the flagship of the PRO TREK brand.

An outdoor brand in step with the times

In 2022, PRO TREK added a focus on promoting a deeper connection with nature. This included developing watches with key resin components made from plant-derived, renewable bio-based materials, and expanding the lineup of models equipped with Tough Solar technology, harnessing natural sunlight for power.

Exploring new sustainable options

The PRG-340SC features a highly comfortable Dura Soft band made with recycled resin. Scraps from resin product manufacturing are crushed into chips, kneaded into a silicone base, and transformed into vibrant, randomly patterned textures that evoke the rugged beauty of stones and sand.

Outdoor gear committed to ongoing evolution

The PRG-340B features bio-based resin in key resin components and CASTLON®, a 100% plant-derived nylon material, for the cloth band. The band is treated with flame retardant, making it resistant to burn marks from campfire sparks.
