The short answer

The closest alternative to the Casio GM-6900 is the Citizen Promaster Diver — common cross-shop and Visually similar. If price is the constraint, the Swatch Taste at $130 (vs $270 for the GM-6900) covers most of the same brief. From the independents, the Rockwell Time 50mm is the standout microbrand take — visually similar and Quartz. Stepping up, the Citizen Promaster Skyhawk A-T ($671) is where the same idea goes with a bigger budget.
