The short answer

The closest alternative to the Omega Seamaster 300 Co Axial Master Chronometer 41mm is the Omega Seamaster 300 Co Axial Master Chronometer 41mm ($15,700) — shared caliber (Omega 8912) and Same family (Seamaster). If price is the constraint, the Longines HYDROCONQUEST GMT at $3,350 (vs $8,000 for the Seamaster 300 Co Axial Master Chronometer 41mm) covers most of the same brief. From the independents, the MMI Watches Turret 300M - Model: TR1-WL (STEEL BLACK) (NO DATE) is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Blancpain Bathyscaphe ($17,100) is where the same idea goes with a bigger budget.
