G-Shock 2100 Series Analog/Digital Watch. GA2100BM-7A2 - The "Cool Blue" CasiOak

The GA-2100BM-7A2 is a masterclass in Crisp Contrast. It features the same world-famous octagonal "CasiOak" silhouette but replaces the warm tones with deep blues on the dial and the day-of-the-week indicator. The result is a watch that feels significantly "colder" and more professional than its multi-colored siblings, while still retaining that laid-back summer energy.

Built with the Carbon Core Guard structure, it is incredibly lightweight (51g) and sits only 11.8mm off the wrist. This makes it the ideal "all-day" watch for someone who wants the protection of a G-Shock but the sleekness of a modern dress-casual timepiece.

Key Performance Features
