The short answer

The closest alternative to the Grand Seiko SLGB023 is the Grand Seiko SLGA015 ($12,600) — same family (Evolution 9) and Pro diver. If price is the constraint, the Seiko Prospex Sea at $1,100 (vs $12,400 for the SLGB023) covers most of the same brief. From the independents, the MMI Watches Turret 300M - Model: TR2-OR (MIDNIGHT BLUE) (NO DATE) (OLD RADIUM) is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Omega Seamaster 300 Co Axial Master Chronometer 41mm ($15,700) is where the same idea goes with a bigger budget.
