Frequently Asked Questions

Find quick answers to the most common questions about our product.

This is a 100% genuine G-Shock GA-2100. We start with the original timepiece and professionally upgrade the exterior. You’ll receive all official documents, guarantees, and even the original strap and dial, ensuring you have the real deal with a premium, custom-engineered metal finish.

Not at all. The legendary internal Carbon Core Guard structure remains fully intact. We have simply swapped the resin exterior for high-grade 316L stainless steel. You get a significantly more premium feel and executive look without sacrificing the world-class durability you expect from this series.

Absolutely. This was designed to be the ultimate one-watch solution. The brushed steel octagon bezel provides a sophisticated, high-end aesthetic that fits perfectly under a suit jacket, while the rugged internals are built to handle high-intensity gym sessions and outdoor adventures without breaking a sweat.

Yes, it maintains its full 200-meter water resistance rating. The modification is purely aesthetic to the outer casing and does not compromise the factory-sealed movement. Whether you are swimming, showering, or diving, your timepiece is engineered to stay bone-dry and functional in any environment.
