The short answer

The closest alternative to the Casio GA-B2100BEG is the Casio EFB-108D ($150) — looks nearly identical and Quartz. If price is the constraint, the Swatch Masa at $80 (vs $165 for the GA-B2100BEG) covers most of the same brief. From the independents, the Filippo Loreti Watches Oscura All Black 45mm Leather is the standout microbrand take — looks nearly identical and Quartz. Stepping up, the Tissot T-Race ($650) is where the same idea goes with a bigger budget.
