Tough, innovative, functional beauty — reimagined in sharp, minimalist style.

The GST-B1000D carries on the G-SHOCK heritage of tough construction and design rooted in functional beauty, reconstructing this legacy to achieve a polished, sleek expression.

The bezel goes logo-free for a clean, modern look, while three separate finishes — vertical hairline, circular hairline, and mirror polishing — create a rich and sophisticated textural appeal that changes as light is reflected at different angles. The mirror- and hairline-finished solid stainless-steel band is paired with a tri-fold clasp also crafted from solid stainless steel. This sharp, flat design takes you from business meetings to casual settings to outdoor activities with ease.

We’ve incorporated details from the DW-5000C, the very first G-SHOCK, adding sporty touches like the original’s signature bezel shape and brick pattern. The GST-B1000D-1AJF features accent colours inspired by the first G-SHOCK: red symbolizing the passion to take on challenges, blue representing water resistance, and yellow signifying outstanding shock resistance.

This is a timepiece built to be tough. A metal bezel guards against impact, while the carbon-reinforced resin case protects the module. Urethane buffering components where the metal band meets the case absorb shock and reduce stress on the joints — enhancing durability and ensuring a more secure connection. Adhesive glass bonding and a compact module design make for a slimmer, lighter watch, without compromising shock resistance. All of this comes together in an exacting combination of comfort, toughness, and everyday usability.

Compact form, minimalist design, and rugged performance — this timepiece is an all-around companion, ready for whatever comes your way.

Reconstructing the original

The first-ever G-SHOCK, the DW-5000C, came out I 1983, giving the world the concept of a tough timepiece by rewriting the rules of watchmaking. Inheriting this philosophy and design, the G-STEEL GST-B1000 reconstructs the G-SHOCK as a metal timepiece imbued with a contemporary sensibility. Accents in red, blue, and yellow nod to the original G-SHOCK, representing the passion to take on challenges, water resistance, and shock resistance, respectively. The brick pattern and octagonal bezel stay true to the original, while quietly reminding you to live in the here and now.

Minimalist, metal, balance

Balancing feel and function — Our constant questioning of what is truly necessary led us to embrace a subtractive aesthetic. The result is a design of pared-down beauty, reflected in a case measuring less than 44.2 mm in diameter with an 11.6 mm profile, and a total weight of 118 grams, for a minimalist metal watch that blends seamlessly with any style.

Single hairline finishes trace the contours

Single hairline finishes on the surface exude precision and brilliance, while the bezel goes logo-less, evoking a minimalist aesthetic. A combination of straight and circular hairline finishes, along with mirror polishing, creates a look that shifts with the light, subtly highlighting the metal’s textural appeal.

The stainless-steel bracelet, which was developed for the GST-B1000, is treated with a hairline finish and mirror polish. The newly developed tri-fold clasp provides an elegant form and a secure fit. Its understated presence enhances the overall look with a sense of quiet sophistication.

Elegant and strong, with a solid core

Strength is not simply something shown on the outside. The G-SHOCK philosophy — the reverse, internal protection from external impact — informs every aspect of the internal structure of this timepiece. The case is made of carbon fibre-reinforced resin, and urethane buffering components are installed to help absorb impact to where the band and case connect, as well as to increase the strength of the metal band connections. In addition, the use of adhesive glass attachment and a compact module allow for the flexible absorption of external impact and create a form that is strong, lightweight, and slim.
