Casio G-Shock GBM-2100A-1A2JF Men’s Watch, Black, Metal Cover, Bluetooth, Tough Solar, Biomass Plastic, Authentic Japanese Product

G-SHOCK, the tough watch that has continued to evolve in pursuit of unrelenting strength since its launch in 1983, has released this metal-covered model that maintains the slim design characteristic of the 2100 series while also featuring smartphone linking and Tough Solar technology. While retaining the octagonal form of the 2100 series, the GBM-2100 features a metal bezel, smartphone linking, and Tough Solar technology. Available in three colors: classic black, blue with vapor-deposited coating, and green, the dial is also environmentally friendly, thanks to its biomass plastic band. This model is suitable for a wide range of occasions, from casual to business. The GBM-2100 represents an evolution of the metal-covered 2100 series, combining toughness with stylish design.
