The short answer

The closest alternative to the Casio GBM-2100A is the Casio ECB-2300D ($280) — looks nearly identical and Quartz. If price is the constraint, the Swatch Big Bold Jelly at $125 (vs $280 for the GBM-2100A) covers most of the same brief. From the independents, the Jorg Gray Watches JG8400 is the standout microbrand take — visually similar and Quartz. Stepping up, the Tissot T-Race ($650) is where the same idea goes with a bigger budget.
