The Casio G-SHOCK GA-2100LXB-1A9DR is the gold-accented version of the all-resin LUXE BLACK. It shares the same ultra-light 51g Carbon Core Guard construction and fully blacked-out matte finish as its silver sibling — but swaps in warm gold vapor-deposited hour markers that add a subtle, luxurious shimmer against the stealth black dial.
At just 51g with no metal bezel, it's the lightest way to wear LUXE BLACK with a touch of warmth. 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's the difference between the 1ADR (silver) and 1A9DR (gold)?
The two GA-2100 LUXE BLACK models are identical in every way except the accent colour. The 1ADR has silver vapor-deposited markers for a cooler, more understated shimmer. The 1A9DR uses gold vapor-deposited markers for a warmer, slightly more luxurious feel. Same case, same weight, same functions, same band.
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 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. The black-and-gold combination gives this LUXE BLACK a warmer, more luxurious feel compared to the silver version — and at 51g it's the most comfortable to wear all day. A great gift for birthdays, Father's Day, graduations and milestones.
