Casio G-Shock G-Steel GST-B1000D-3AER – Elegance and durability in one package

The Casio G-Shock G-Steel GST-B1000D-3AER is a high-end wristwatch that combines the renowned durability of the G-SHOCK series with a minimalist and modern design. This watch is designed for those who value a strong structure, technological advancement and refined finishing-

The GST-B1000D-3AER represents G-SHOCK's new design philosophy, combining functional beauty with bold simplicity. The watch body is made of stainless steel and bio-based carbon fiber, making it lightweight but exceptionally durable. The watch's polished and brushed steel bracelet has a triple locking mechanism that ensures a secure fit. The combination of three different surface treatments – vertical and rotary sanding, as well as mirror polishing – creates a refined texture that reflects light beautifully from different angles. The minimalist look is completed by a logo-free bezel and a black, brick-like patterned dial inspired by the original DW-5000C.

This model is built with Carbon Core Guard construction, where carbon fiber-reinforced resin protects the watch’s core components from the effects of shock and vibration. A metal bezel serves as additional protection and emphasizes the watch’s premium finish. Urethane shock-absorbing parts used at the junctions of the watch’s strap and case reduce shock and improve wearing comfort. This makes the watch ideal for an active lifestyle – it can withstand water, shocks and constant use.
