The short answer
The closest alternative to the Casio GA-2100 is the Swatch Big Bold Irony ($205) — looks nearly identical and Quartz. From the independents, the Straton Sportiva and Volante is the standout microbrand take — square case. Stepping up, the Tissot T-Race MotoGP 2026 ($775) is where the same idea goes with a bigger budget.
