The short answer

The closest alternative to the Casio GST-B100 is the Tissot T-Race ($650) — common cross-shop and Racing chrono. If price is the constraint, the Casio EFV-620D at $120 (vs $385 for the GST-B100) covers most of the same brief. From the independents, the Jorg Gray Watches JG2500 is the standout microbrand take — racing chrono and Looks nearly identical. Stepping up, the Citizen ATTESA ($1,995) is where the same idea goes with a bigger budget.
