Casio G-shock "CasiOak"

With a bold, unmistakable profile, the G-SHOCK GA-2100 is a watch that combines design and durability in a perfect synthesis of style and functionality. Its distinctively shaped octagonal case measures 48.5 × 45.4 × 11.8 mm, combining compactness and solidity. Made of carbon fiber-reinforced resin — thanks to Carbon Core Guard technology — it offers superior protection against shocks and stress, while weighing just 51 grams for optimal comfort. The resin strap ensures a stable, comfortable fit, accommodating wrists between 145 and 215 mm. The model's ruggedness is reinforced by its shock resistance and water resistance up to 20 bar (200 meters), making it ideal for water sports and outdoor activities without compromise. Behind its modern design lies an advanced technological heart: the GA-2100 features an analog-digital movement with world time display across 31 time zones (48 cities + UTC), daylight saving time on/off function, and the ability to quickly switch between time zones. Timekeeping performance is managed with precision: a 1/100-second stopwatch, measuring up to 59 minutes 59.99 seconds before switching to measurement in seconds up to 23 hours, 59 minutes, and 59 seconds; a countdown timer adjustable up to 24 hours, in increments of 1 second, 1 minute, and 1 hour. The GA-2100 doesn't overlook everyday practicality, with 5 daily alarms, hourly time signal, and a mute function for personalized management of audible notifications. Lighting is provided by the dual Super Illuminator LED light, which illuminates both the analog dial and the digital display, with a selectable duration of 1.5 or 3 seconds, ensuring maximum visibility in any light condition. Neobrite on the hands ensures readability even in the dark. The dial is protected by scratch-resistant mineral glass, while the hand-shift function allows the digital information to be viewed without obstruction. The watch's reliability is ensured by a system powered by two SR726W batteries, with an estimated lifespan of about 3 years. The G-SHOCK GA-2100 is not just an accessory, but an icon of durability and performance, designed for those seeking a watch that combines aesthetics, technology, and ruggedness without compromise.
