Celebrate 50 years of Casio watches with the transcendent PRO TREK PRW-61SS-2DR. This commemorative watch features a special color scheme and design, evoking the ever-changing nature of the sky, sea, and sunlight. Its dial ring is laser-etched with a fluted pattern and the case back pays homage to the first-ever Casiotron released in 1974. Embodying both Casio's origin and innovation, this is a 50th anniversary-worthy timepiece.
