The short answer

The closest alternative to the Omega Speedmaster Calibre 321 Chronograph 38 6mm is the Omega Speedmaster Calibre 321 Chronograph 42mm ($77,900) — shared caliber (Omega 321) and Same family (Speedmaster Calibre). If price is the constraint, the Omega Speedmaster Calibre 321 Chronograph 39 7mm at $17,300 (vs $108,900 for the Speedmaster Calibre 321 Chronograph 38 6mm) covers most of the same brief. From the independents, the Baltic Scalegraph Classic is the standout microbrand take — racing chrono and Looks nearly identical. Stepping up, the Hublot Big Bang Tourbillon Chronograph Cathedral Minute Repeater Polished Titanium 45mm ($338,000) is where the same idea goes with a bigger budget.
