Celebrate 50 years of Casio watches with a transcendent PRO TREK that symbolizes Casio’s determination to stay true to who we are, while constantly innovating. The PRO TREK PRW-61SS features a special commemorative color scheme and design with Casio colors, materials, and finishes that evoke the omnipresent yet ever-changing nature of the sky, the sea, and the sunlight — shining today and forevermore. The design features a dial ring laser-etched with a fluted pattern. The logo is engraved on the case back, paying homage to the first-ever Casiotron released back in 1974. This very special 50th anniversary-worthy PRO TREK embodies both the origin of Casio watches and the half-century of groundbreaking innovation that followed.

FEATURES

color and design evoking the sky, sea, and sunlight

In homage to the original Casiotron, the blue IP bezel is laser-etched with a fluted pattern. Gold-hued glass vapour deposition is applied to the dial ring, and gold-color accents adorn the inset dial ring and crown as well, creating striking highlights against the key color of blue.

Carefully selected materials: A passion for the natural life

The band is made of flame-retardant cloth that holds up even when hit by sparks from cooking or campfires, resisting burn marks. The cloth material is made of recycled PET material from plastic bottles and other plastics. The case and case back are made with bio-based resin, which is produced using renewable organic resources and is expected to help reduce environmental impact. We think these materials send the right message about our line of premiere outdoor gear, PRO TREK.

The case back is engraved with an original logo crafted in celebration of the 50th anniversary of Casio watches. The engraving pays homage to the logo that was on the case back of the first-ever Casiotron, now specially redesigned to mark this significant milestone.
