The short answer

The closest alternative to the Casio GM-B2100SD is the Tissot T-Race ($650) — common cross-shop and Looks nearly identical. If price is the constraint, the Casio EQS-960PB at $240 (vs $600 for the GM-B2100SD) covers most of the same brief. From the independents, the Elliot Brown CANFORD: 202-004 is the standout microbrand take — looks nearly identical and Quartz. Stepping up, the Citizen ATTESA ($2,250) is where the same idea goes with a bigger budget.
