GA100BNR-1A Watch by G-Shock.
Make a bold, powerful statement with the Ignite Red line in the iconic black and fiery red that embody the ultimate toughness of the G-SHOCK brand.
We have injected a few of our flagship models — the octagonal GAB2100 with Bluetooth and solar power; the GA100, GA2200, and GA700 with signature oversized case — with the strength and passion of the black and red G-SHOCK brand colors.
Deep, blazing red accents against striking, dark black give these watches, and the wrist that wears them, a kick of cool confidence.
