CASIO G-SHOCK G-STEEL GST-B1000BD-2ADR SOLAR MEN WATCH

The GST-B1000BD-2ADR is the all-black ion-plated G-Steel — G-Shock's refined metal-body line, redesigned for June 2026 with a logo-less bezel, bio-based carbon resin inner case, and a borderless minimalism that strips back everything except the structural essentials. Black ion plating covers the stainless steel bezel, the solid stainless steel band, the case back, the side buttons, the screw-lock crown, the tri-fold clasp, and even the individual screws — every metallic surface is coated. The combination of hairline and mirror finishes across the bracelet links creates a shifting depth as light moves across the surface, and the logo-less bezel takes on a lustrous quality that only black ion plating can achieve.

Module 5748 powers the G-Steel platform with Tough Solar charging and Bluetooth smartphone link via the CASIO WATCHES app for automatic time correction. Carbon Core Guard structure — a carbon-reinforced resin inner case protected by the stainless steel outer bezel — delivers shock resistance without the bulk of a full-resin build. The result is a 200-metre water resistant G-Shock at 46.9 × 44.2 × 11.6 mm and 118 grams that wears slimmer and lighter than its dimensions suggest. Analog display with three hands (hour, minute, second) and two sub-dials (24-hour and day indicator), LED Super Illuminator, Neobrite lume, 1-second stopwatch, countdown timer, and daily alarm. Solar powered — no battery changes required.

Why You'll Love It

• The all-black ion plating is applied to every metallic surface — bezel, band, case back, buttons, crown, clasp, screws. There are no silver or exposed steel elements breaking the finish. The result is a monolithic dark metal watch that changes character as light shifts across the hairline and mirror-polished bracelet links — reflective and lustrous under direct light, near-invisible matte black in shadow.
• The logo-less bezel is a deliberate design choice for the 2026 GST-B1000BD. Removing the G-Shock branding from the bezel surface gives the watch a cleaner, more architectural look — the focus shifts entirely to the structural form. The brick pattern inherited from the original 1983 G-Shock is still present in the case design, but the bezel itself is uninterrupted black ion-plated steel.
• Carbon Core Guard structure uses a bio-based carbon-reinforced resin inner case protected by the stainless steel outer bezel. The carbon core absorbs shocks while the metal bezel guards against direct impacts — you get G-Shock toughness in a slimmer, lighter package than a full-metal build. At 11.6 mm thick, this is noticeably slimmer than most metal G-Shocks.
• Tough Solar means you never change a battery. The solar cell charges from any light source — sunlight, office fluorescent, even indoor LED. Five months of operation on a full charge with no light exposure, and the power saving function extends that to eighteen months by stopping the hands when the watch is left in the dark.
• Bluetooth auto time correction keeps the watch accurate without any manual setting. Every time the watch connects to your phone via the CASIO WATCHES app, it adjusts itself. Accurate to ±15 seconds per month even without the connection — and effectively perfect with it.
• The solid stainless steel bracelet with one-touch tri-fold clasp is engineered specifically for the GST-B1000 — not a generic Casio bracelet adapted to fit. The combination of hairline and mirror finishes across the link surfaces gives the band a quiet but solid sense of presence that matches the weight and intent of the watch head.
