The short answer

The closest alternative to the Omega Seamaster Diver 300M Co Axial Master Chronometer Chronograph 44mm is the Omega Seamaster Diver 300M Co Axial Master Chronometer Chronograph 44mm ($14,000) — shared caliber (Omega 9900) and Same family (Seamaster Diver 300M). If price is the constraint, the Omega Seamaster Diver 300M Co Axial Master Chronometer Chronograph 44mm at $9,200 (vs $27,300 for the Seamaster Diver 300M Co Axial Master Chronometer Chronograph 44mm) covers most of the same brief. From the independents, the Oceaneva WaveRacer 1000m Mechanical Chronograph is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Rolex Deepsea ($68,100) is where the same idea goes with a bigger budget.
