The short answer

The closest alternative to the Seiko Prospex SPEEDTIMER SPEEDTIMER Mechanical Chronograph Limited Edition is the Seiko Prospex SPEEDTIMER ($3,000) — shared caliber (8R46) and Same family (Prospex SPEEDTIMER). If price is the constraint, the Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition at $1,150 (vs $3,000 for the Prospex SPEEDTIMER SPEEDTIMER Mechanical Chronograph Limited Edition) covers most of the same brief. From the independents, the Dan Henry 1972 is the standout microbrand take — common cross-shop and Racing chrono. Stepping up, the Bremont Jaguar Limited Edition ($6,900) is where the same idea goes with a bigger budget.
