The short answer

The closest alternative to the Casio GST-B400 is the Casio G-SHOCK G-STEEL GST-B500 ($314) — same family (G-Shock) and Looks nearly identical. If price is the constraint, the Casio AQ-S820W at $65 (vs $350 for the GST-B400) covers most of the same brief. From the independents, the Rockwell Time Coliseum Fit (digital) is the standout microbrand take — visually similar and Quartz. Stepping up, the Tissot T-Touch Connect Solar ($1,350) is where the same idea goes with a bigger budget.
