CASIO G-SHOCK GM-B2100D-1A

R 16,000.00

The GM-B2100D-1A is what happens when G-Shock grows up… but refuses to behave. Classic “CasiOak” octagonal design, now wrapped in full stainless steel, paired with Bluetooth smarts and solar power. It’s tough, polished, and quietly over-engineered — the kind of watch that survives chaos and still looks sharp at dinner.

Key Features

  • Tough Solar Power — charges from any light source, so battery anxiety is not invited.
  • Bluetooth Connectivity — syncs with your phone for accurate time, world time updates, and easy settings via the G-Shock app.
  • Full Stainless Steel Case & Bracelet — premium weight, solid feel, zero nonsense.
  • Carbon Core Guard Structure — lightweight strength protecting the module inside.
  • Shock Resistant (G-Shock DNA) — built to take hits without flinching.
  • 200 m Water Resistance — swimming, rain, rough days… all fine.
  • Super Illuminator (Double LED) — dial and digital display glow on command.
  • Octagonal “CasiOak” Design — iconic shape, modern execution.
  • World Time (38 Time Zones) — global coverage without mental math.
