The short answer

The closest alternative to the Omega Speedmaster X 33 Marstimer Chronograph 45mm is the Bell & Ross BR 126 SPORT HERITAGE & FLYBACK ($6,372) — racing chrono and Looks nearly identical. If price is the constraint, the Hamilton Khaki Aviation X-Wind GMT Chrono Quartz at $1,245 (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 Zenith Defy Skyline Chronograph ($14,500) is where the same idea goes with a bigger budget.
