The short answer
The closest alternative to the Omega Speedmaster X 33 Marstimer Chronograph 45mm is the Omega Speedmaster Racing Co Axial Master Chronometer Chronograph 44 25mm ($10,400) — same family (Speedmaster) and Moonwatch lineage. If price is the constraint, the Seiko Astron GPS Solar 2025 Limited Edition at $2,900 (vs $7,000 for the Speedmaster X 33 Marstimer Chronograph 45mm) covers most of the same brief. From the independents, the Astor + Banks Chrono is the standout microbrand take — racing chrono and Looks nearly identical. Stepping up, the Omega Speedmaster Moonphase Co Axial Master Chronometer Moonphase Chronograph 43mm ($19,300) is where the same idea goes with a bigger budget.
