Casio GA-100 Original Black Replacement Band

Restore your watch to its factory-fresh tactical glory with the Casio GA-100 Original Black Replacement Band (Genuine Casio Part No: 10347688 / Strap Code: 776-EJ4-16). Specifically molded to meet Casio's strict armor-grade quality standards, this authentic polyurethane resin watch strap is the definitive solution for replacing a weathered, torn, or aged band.

These curves are engineered to flex dynamically with your wrist movements, ensuring that your watch delivers its legendary "slim and comfortable" fit while keeping its rugged "sporty design" intact.

Key Features

• Original Factory Precision: This is a genuine Casio OEM part, guaranteeing a flawless, zero-gap integration with your existing G-Shock watch case, restoring its structural integrity.
• Heavy-Duty Double-Pin Buckle: Features a high-strength, matte-finished stainless steel double-tang buckle that distributes tension evenly across the strap, preventing accidental opening during high-impact sports.
• Extreme-Durability Resin: Formulated from Casio's signature synthetic polyurethane resin, making the strap completely impervious to rot or cracking caused by heavy exposure to sweat, saltwater, chlorine, or mud.
• Accordion Shock-Absorbent Curves: Designed with integrated flexible waves near the lugs that act as miniature shock absorbers, safely dissipating mechanical impact forces away from the watch case during sudden drops.
• Broad-Shouldered Profile: While anchoring securely into a specialized internal lug system, the outer strap geometry flares out dynamically to a muscular width of 29 mm, providing a cohesive look on robust watch faces.
