The short answer

The closest alternative to the Omega Seamaster Diver 300M Co Axial Master Chronometer 42mm is the Omega Seamaster Diver 300M Co Axial Master Chronometer 42mm ($9,600) — shared caliber (Omega 8800) and Same family (Seamaster Diver 300M). If price is the constraint, the Omega Seamaster Diver 300M Co Axial Master Chronometer 42mm at $6,300 (vs $16,600 for the Seamaster Diver 300M Co Axial Master Chronometer 42mm) covers most of the same brief.
