The Casio G-SHOCK GA-2100LXB-1ADR is the purest expression of the LUXE BLACK concept — a fully blacked-out 2100 with no metal bezel, just matte black resin from end to end. At just 51g with Carbon Core Guard construction, it's significantly lighter than the G-STEEL version, making it the LUXE BLACK you'll forget you're wearing until someone asks about it.
Silver vapor-deposited hour markers create a delicate metallic shimmer against the matte black dial, while the redesigned slim hands and textured surface suppress reflections for a quiet, controlled aesthetic. Underneath, it's full G-SHOCK: shock-resistant construction, 200m water resistance, world time, stopwatch, countdown timer, five alarms and dual LED illumination.

Frequently Asked Questions
What is Carbon Core Guard?
Carbon Core Guard is G-SHOCK's carbon-fibre reinforced case structure. It uses a carbon-fibre insert within the resin case to improve shock resistance and rigidity while keeping the watch lighter than a metal-bezeled model. It's the reason the GA-2100 weighs just 51g despite its robust construction.
What is the LUXE BLACK series?
LUXE BLACK is a sub-collection within the G-SHOCK 2100 (CasiOak) line. It reinterprets the iconic 2100 design through a minimalist lens — matte black finishes, redesigned slim hands, vapor-deposited markers and subtle accents. It's designed for people who want G-SHOCK toughness with a more refined, understated aesthetic.
Is this watch suitable for swimming?
Yes. With 200m (20 bar) water resistance and shock-resistant construction, the GA-2100LXB is suitable for swimming, surfing and recreational water sports. It's not designed for scuba diving with helium.
What is bio-based resin?
Bio-based resin is a material partially derived from renewable organic sources such as castor seeds or corn, reducing reliance on petroleum-based plastics. It performs identically to standard resin in terms of durability and comfort, with a smaller environmental footprint.
How long does the battery last?
Approximately 3 years with normal use (SR726W × 2).
Is this a good gift?
Absolutely. At 51g it's the most wearable G-SHOCK in the LUXE BLACK range — perfect for men who appreciate minimalist design, lightweight comfort and everyday toughness. A great gift for birthdays, Father's Day, graduations and milestones.
