Why Choose the Casio G-Shock GST-S310D-1A?

Shock Resistance with Style

True to its G-Shock legacy, this model incorporates the iconic shock-resistant structure that has made the line world-famous. The hybrid stainless steel and resin construction not only absorbs impacts but also gives the watch a sleek metallic edge, striking a balance between ruggedness and elegance.

Tough Solar Charging for Everyday Power

Forget about changing batteries. The GST-S310D-1A is powered by Casio’s Tough Solar technology, efficiently converting both natural and artificial light into energy. Once fully charged, it can run for months without additional exposure, thanks to its energy-saving features.

Layered Guard Structure for Superior Durability

The inner workings of the watch are shielded by a dual-layer structure that reduces shock from external forces. This layered design enhances protection for the module while also contributing to the watch’s bold, modern look.

Stainless Steel Band for a Premium Feel

The metal band provides a sturdy yet comfortable fit, suitable for both professional and casual wear. Its brushed silver finish adds refinement, while the fold-over clasp with double push-button safety ensures a secure grip all day long.

LED Light with Full Auto Function

Time doesn’t stop when the sun goes down. The GST-S310D-1A is equipped with a Super Illuminator LED backlight that offers high-brightness illumination at the press of a button—or automatically with a flick of the wrist when in low-light conditions.
