Casio G-Shock GLX5600KB-1 Black Resin Digital Diver Watch

Surfing Heritage Meets Square Toughness

The Casio G-Shock GLX5600KB-1 is part of the brand’s long-standing G-LIDE surf series, created in collaboration with professional surfer Kanoa Igarashi. It keeps the classic square 5600 case profile—lightweight, slim, and instantly recognizable—while adding functionality tailored for ocean athletes.

Built for the Breaks

This model features tide and moon graph functions, critical tools for surfers planning their next session. The digital display, framed in matte black resin, is optimized for clarity against the motion of sun and surf. Behind the face, the module is housed in the shock-resistant case G-Shock is known for, backed by 200-meter water resistance, making it safe for everything from paddling out to post-surf showers.

Design with Purpose

At just over 12mm thick, the GLX5600KB-1 wears comfortably even under a wetsuit. The strap is resin with a surf-ready buckle closure, built to withstand saltwater and repeated use. Subtle branding ties it to Igarashi’s input while keeping the aesthetic understated, making it equally at home on land.

Daily Utility Beyond the Ocean

In addition to tide graphs, the watch carries world time, stopwatch, countdown timer, multi-function alarms, and a full auto-calendar. An EL backlight ensures legibility in low-light conditions, whether pre-dawn surf checks or late-night beach walks.

A Partner for Surf and Street

The GLX5600KB-1 blends the G-Shock reputation for resilience with surf-specific functionality and athlete collaboration credibility. For fans of the square G-Shock case who want real-world surf functionality, it’s a natural choice.

Ready to ride waves or simply carry surf heritage into everyday wear, the Casio G-Shock GLX5600KB-1 stands as a practical companion with undeniable style.
