Bio-Based Resin Construction

The Casio G-SHOCK GMD-S5600NC-2 is a square digital quartz watch built with a bio-based resin case and strap. Its 40.50 mm case houses a green dial protected by mineral crystal. Designed for women seeking a sports watch, it delivers 200m water resistance and shock resistance for daily durability.

Upgrade From Basic Digital Watches

This model replaces simple time-only digital watches by adding a 1/100 second stopwatch, countdown timer, and multi-function alarm. The jump is worth it when you need precise interval timing, recurring reminders, or a flash alert with LED backlight and afterglow for low-light visibility. A full auto calendar handles month, day, and date automatically.

Fits Active Daily Routines

The resin band fastens with a buckle clasp for a secure fit during movement. Quartz movement keeps time without winding, while 12/24-hour display options suit personal preference. It frees you from frequent battery changes and fragile construction, standing up to swimming, training, and everyday knocks with its 200m rating and shock-resistant build.

Questions about this item

What strap width does the 40.50 mm resin case accept?

The lug width matches the 40.50 mm case size, so a 20 mm replacement strap will fit the bio-based resin band supplied.

How do I set the 12/24-hour display without losing the auto calendar?

Hold the adjust button until the time zone flashes, press mode once to reach the 12/24 setting, toggle with the forward button, then press adjust again to exit — the calendar stays intact.

When should the mineral crystal be replaced?

Replace the mineral crystal only if a deep scratch or crack impairs the digital display readability; the 200m water resistance seal must then be pressure-tested.
