CASIO 50TH ANNIVERSARY
Celebrate 50 years of Casio watches with a commemorative PRO TREK timepiece that sparkles with Casio passion for new value and constant innovation.
The PRW-6900ZE embodies the spirit of craftsmanship inspired by the excitement of “making something from nothing”—the thrill of going from “0” to “1.” This approach, the essence of Casio creativity, requires a dedication to overcoming challenges and boldly breaking free of conventional thinking — no matter how well-established, perfected, and complete it may seem — to present innovative new concepts and ideas.
The black and gold color scheme evokes the first flicker of light, that spark of innovative craftsmanship, where the creation of new value begins.
Equipped with Tough Solar that charges the watch from sunlight or even indoor light, this timepiece also comes in special packaging made with recycled materials for an anniversary design that honors the environment.
Celebrate this special milestone for Casio watches with a stunning anniversary timepiece that brings the commemorative colors and design to life.
