The Casio G-SHOCK G-STEEL GM-2100LXB-1ADR is the refined side of G-SHOCK. Part of the LUXE BLACK series within the popular G-STEEL 2100 line, it strips away the usual colour and branding noise in favour of a blacked-out, minimalist aesthetic — matte black dial, black ion-plated metal bezel, black bio-based resin band and subtle silver accents that only reveal themselves up close.
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. The GM-2100LXB proves you don't have to choose between toughness and sophistication.

Frequently Asked Questions
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 silver accents. It's designed for people who want G-SHOCK toughness with a more refined, understated aesthetic.
What's the difference between the GM-2100LXB and the standard GM-2100?
Both share the same CasiOak case shape, shock resistance, 200m water rating and function set. The LXB upgrades the dial with a deeper matte black finish, newly designed slim hands with extended proportions, vapor-deposited hour markers and silver accents on the inset dials. It's the same watch underneath, with a more premium, refined surface treatment.
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 LUXE BLACK's blacked-out minimalist look appeals to a wider audience than typical G-SHOCKs — it works for men who appreciate understated design as much as those who love G-SHOCK toughness. A great gift for birthdays, Father's Day, graduations and milestones.
