The short answer

The closest alternative to the Casio GR-B300 is the Tissot Supersport Chrono ($575) — common cross-shop and Racing chrono. If price is the constraint, the Casio EFV-620D at $120 (vs $330 for the GR-B300) 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 Promaster Land U822 ($521) is where the same idea goes with a bigger budget.
