The short answer

The closest alternative to the Omega Seamaster Planet Ocean 6000M Co Axial Master Chronometer 45 5mm is the Omega Seamaster 300 Co Axial Master Chronometer 41mm ($8,000) — shared caliber (Omega 8912) and Same family (Seamaster). If price is the constraint, the Breitling Superocean Automatic at $5,700 (vs $13,900 for the Seamaster Planet Ocean 6000M Co Axial Master Chronometer 45 5mm) covers most of the same brief. From the independents, the Audaz Ocean Raider is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Blancpain Fifty Fathoms Automatique ($52,600) is where the same idea goes with a bigger budget.
