The Casio G-SHOCK G-STEEL GM-2100LXB-1A9DR is the gold-accented variant of the LUXE BLACK series. It shares the same blacked-out, minimalist foundation as its silver sibling — matte black dial, black ion-plated metal bezel, redesigned slim hands and bio-based resin band — but swaps in warm gold accents on the inset dials and vapor deposition ring, adding a subtle warmth that catches the light without breaking the stealth aesthetic.
Underneath the premium finish, it's still a G-SHOCK through and through: shock-resistant construction, 200m water resistance, world time, stopwatch, countdown timer, five alarms and dual LED illumination. For those who want the refinement of LUXE BLACK with a touch more presence.

Frequently Asked Questions
What's the difference between the 1ADR (silver) and 1A9DR (gold)?
The two LUXE BLACK models are identical in every way except the accent colour. The 1ADR has silver accents on the inset dials and vapor deposition ring for a cooler, more understated look. The 1A9DR uses gold accents for a warmer, slightly more luxurious feel. Same case, same bezel, same functions, same band.
What is the LUXE BLACK series?
LUXE BLACK is a premium sub-collection within the G-SHOCK GM-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.
What does "CasiOak" mean?
CasiOak is the nickname given to the GA-2100 / GM-2100 series by the watch community because of its octagonal bezel shape. It's become one of the most popular G-SHOCK designs due to its slim profile and versatile styling.
Is this watch suitable for swimming?
Yes. With 200m (20 bar) water resistance and shock-resistant construction, the GM-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.
What is the hand shift feature?
When you switch to a digital-display mode (stopwatch, timer, world time), the analog hands automatically move out of the way so they don't block the digital readout. They return to the correct time when you switch back.
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 the LUXE BLACK a more premium, luxurious feel compared to the silver version — making it especially fitting as a birthday, Father's Day, graduation or milestone gift for men who appreciate refined aesthetics.
