The short answer

The closest alternative to the Omega Seamaster Diver 300M Co Axial Master Chronometer 43 5mm is the Omega Seamaster Diver 300M Co Axial Master Chronometer 43 5mm ($10,000) — shared caliber (Omega 8806) and Same family (Seamaster Diver 300M). If price is the constraint, the Sinn U1 S L at $3,532 (vs $10,500 for the Seamaster Diver 300M Co Axial Master Chronometer 43 5mm) covers most of the same brief. From the independents, the Ianos Dytis is the standout microbrand take — pro diver and Visually similar. Stepping up, the Omega Seamaster Diver 300M Co Axial Master Chronometer Chronograph 44mm ($27,300) is where the same idea goes with a bigger budget.
