The short answer
The closest alternative to the Casio GA-2100 is the Casio G-Shock GW-M5610 ($145) — same family (G-Shock) and Square case. If price is the constraint, the Casio W-218H at $30 (vs $110 for the GA-2100) covers most of the same brief. From the independents, the Rockwell Time 747 Chronograph is the standout microbrand take — square case and Visually similar. Stepping up, the Tissot T-Race MotoGP 2026 ($775) is where the same idea goes with a bigger budget.
