Description
Since its launch in 2019, few watches have made as big an impact as the Casio G-Shock GA2100, and the GA2100-1A remains one of the most sought-after colourways in the entire lineup. Nicknamed the "CasiOak" for its striking resemblance to the iconic Audemars Piguet Royal Oak, this black with white hands version delivers instant visual appeal alongside the legendary toughness that defines G-Shock.
The GA2100-1A draws design inspiration from the original 1983 DW-5000C — the very first G-Shock — blending that classic octagonal silhouette with a modern analogue-digital display. The Carbon Core Guard construction uses a highly rigid fine resin containing carbon fibre to achieve what was previously considered impossible for a watch of this calibre: a case just 11.8mm thin. At 45.4mm wide and weighing a mere 51 grams, it sits effortlessly on the wrist — far more wearable than the typical G-Shock, making it equally at home in the office as it is outdoors. The stainless steel case back and mineral glass crystal round out a build that feels premium well beyond its price point.
The black dial is brought to life by white sword-shaped analogue hands and light grey indices, ensuring legibility that the all-black 1A1 stealth version sacrifices in favour of aesthetics. The hand shift feature moves the analogue hands clear of the digital display when needed, giving an unobstructed view of the LCD information below. Neobrite luminous coating on the hands provides reliable low-light readability without draining the battery.
Functionality is purposely clean and straightforward. World time across 31 time zones, a 1/100-second stopwatch, countdown timer, five daily alarms, hourly time signal, and a full auto-calendar to 2099 cover every practical need. A double Super Illuminator LED system lights up both the dial and the digital display independently for excellent visibility in any light. Water resistant to 200 metres and shock resistant, the GA2100-1A is a modern G-Shock classic that has firmly earned its iconic status.
