The short answer

The closest alternative to the Sinn 103 St DIAPAL is the Sinn 144 St DIAPAL ($4,428) — shared caliber (La Joux-Perret 8000) and Racing chrono. If price is the constraint, the Damasko DC66 covers most of the same brief. From the independents, the Kobold Phantom Chronograph is the standout microbrand take — racing chrono and Looks nearly identical. Stepping up, the Omega Seamaster Diver 300M Co Axial Master Chronometer Chronograph 44mm ($9,200) is where the same idea goes with a bigger budget.
