Casio Pro Trek PRW-6900YB-3 Climber Line Radio Tough Solar Men's Watch

The Casio Pro Trek PRW-6900YB-3 Climber Line Radio Tough Solar Men's Watch is a rugged timepiece designed for both the outdoors and urban exploration. Built with durability in mind, its 44.8mm bio-based resin and stainless steel case features a striking octagonal design, with a black ion-plated bezel that gives it a bold, robust look. The textured black dial, inspired by classic campfire cookware like the Dutch oven, is enhanced by an orange seconds hand, reminiscent of glowing campfire embers, adding a touch of adventure to its aesthetic. The watch is equipped with a CORDURA® re/cor™ textile cloth band in khaki green, treated with flame-retardant properties to resist burn marks, making it ideal for camping and outdoor activities. At 67g, the PRW-6900YB-3 remains lightweight, while its durable construction ensures it can handle tough conditions, including temperatures as low as -10°C and up to 100 meters of water resistance. This timepiece offers advanced functionality with a Multi Band 6 radio-controlled time adjustment for precise accuracy and solar-powered Tough Solar technology for reliable performance. The inset dial indicator, shaped like a camping knife blade, adds a unique touch to its rugged design. Whether by the fire or in the city, this versatile watch combines outdoor spirit with modern style, backed by a 2-year Watch Zone warranty.
