CASIO G-SHOCK GA-110RRB-4ADR ICONIC RED 110 ANALOG-DIGITAL WATCH

The GA-110RRB-4ADR is the oversized 110 in G-Shock's Iconic Red — the biggest, boldest canvas in the four-model RRB series, dressed head-to-toe in vivid red with a red vapor deposition dial, inverted LCD, and black accents. The 110's larger case gives the all-red treatment maximum visual impact — more surface area, more red, more presence. Bio-based resin for the bezel and band. The same seamless red-to-red transition from bezel to vapor-deposited dial as the GA-2100RRB, but on a significantly larger and more aggressive form factor.

Module 5146 is different from the GA-2100's 5611 — it's the 110's dedicated platform with its own distinctive capabilities: a 1/1000-second stopwatch (ten times the resolution of the GA-2100's 1/100-second), a speed indicator sub-dial on the analog face with distance input for pace calculations, magnetic resistance, and auto LED light that activates on wrist tilt with an amber glow. World time across 29 time zones (48 cities) with home/world city swapping, 24-hour countdown timer with auto-repeat, five daily alarms with snooze. At 55 × 51.2 × 16.9 mm and 72 grams, the GA-110 is designed to dominate the wrist. Shock resistant, magnetic resistant, 200-metre water resistant. CR1220, approximately two-year battery life.

At a Glance

Why You'll Love It

• The 110 is the oversized silhouette of the Iconic Red series — the one you pick when you want the red to fill the wrist and be impossible to ignore. At 55 × 51.2 mm, it has significantly more surface area than the GA-2100RRB (48.5 × 45.4 mm), and the all-red vapor deposition dial, red bezel, and red band create a monolithic red statement that the smaller silhouettes can't match. If the GA-2100RRB is a red accent, the GA-110RRB is a red announcement.
• The 1/1000-second stopwatch is the GA-110's signature function — ten times the resolution of the GA-2100's 1/100-second stopwatch, with a nearly 100-hour capacity (99:59'59.999"). The speed indicator sub-dial on the analog face lets you input a distance and the watch calculates your speed — a function designed for motorsport, running, and any activity where pace matters. The sub-dial hand sweeps in real time as the stopwatch runs.
• Magnetic resistance — the module is shielded against everyday magnetic fields from phones, tablets, and magnetic accessories. The GA-2100RRB doesn't have this spec. Combined with shock resistance and 200m water resistance, the GA-110RRB is the most robust analog-digital in the Iconic Red series.
• Auto LED light activates on wrist tilt — raise your wrist and the amber LED illuminates the dial without pressing a button. The amber glow against the all-red case creates a warm, atmospheric light effect in the dark. The GA-2100RRB has a white double LED but no auto light function.
• The red vapor deposition dial blends seamlessly into the red bezel and band — the same unified red surface treatment as the GA-2100RRB. The inverted LCD and black accents cut through the red for readability and structural contrast.
• Bio-based resin for the bezel and band. At 72 grams, the GA-110RRB is heavier than the GA-2100RRB (51 g) but lighter than a metal-bezel G-Shock — the oversized presence comes from dimensions, not weight.
