Product Description
The G-SHOCK GA-2100GB-1A, often referred to as the “”CasiOak”” due to its octagonal bezel reminiscent of luxury designs, combines durability with a sleek aesthetic. Its slim profile, measuring 48.5mm in length, 45.4mm in width, and a mere 11.8mm in thickness, houses a robust carbon core guard structure that ensures shock resistance.
The watch features a glossy black resin case and band, complemented by a gold-toned dial achieved through vapor deposition, offering a striking contrast. The dial’s circular hairline finish enhances its metallic sheen, while the Neobrite-coated hour and minute hands, along with the Super Illuminator double LED light, ensure readability in low-light conditions.
Functionality includes 200-meter water resistance, world time across 48 cities, a 1/100-second stopwatch, countdown timer, and five daily alarms. Despite its comprehensive features, the GA-2100GB-1A maintains a lightweight design at 51 grams, offering comfort for daily wear.
Introduced in 2019, the GA-2100 series pays homage to the original DW-5000C, G-SHOCK’s first model, by incorporating its iconic octagonal shape into a contemporary analog-digital format. This design choice has resonated with enthusiasts, earning the “”CasiOak”” moniker and solidifying its status as a modern classic within the G-SHOCK lineup.
