The short answer

The closest alternative to the Casio GMA-S2100 is the Timex Expedition Ridge Chronograph 42mm Silicone Strap Watch ($145) — common cross-shop and Looks nearly identical. If price is the constraint, the Casio AE-1000W at $40 (vs $110 for the GMA-S2100) covers most of the same brief. From the independents, the Elliot Brown SCOTS DG Limited Edition Canford 2024 is the standout microbrand take — visually similar and Quartz. Stepping up, the Citizen Promaster Skyhawk A-T ($596) is where the same idea goes with a bigger budget.
