The short answer
The closest alternative to the Casio GAS-100 is the Casio PRG-601 ($330) — looks nearly identical and Same size. If price is the constraint, the Casio AQ-S820W at $65 (vs $180 for the GAS-100) covers most of the same brief. From the independents, the Jorg Gray Watches JG2500 is the standout microbrand take — looks nearly identical and Same size. Stepping up, the Citizen Promaster Aqualand 200M Depth Meter ($769) is where the same idea goes with a bigger budget.
