Owners widely consider the Casio GBM-2100A the best in the Casioak line, praising its half-metal construction for a premium feel without excessive weight, its positive display, and Neobrite indexes. The Bluetooth connectivity simplifies setting functions via a smartphone app, and the model is cited as a great example of G-Shock's value, durability, accuracy, and comfort. One owner notes that while the metal case is a strong combination, resin models offer more modding flexibility.
