The short answer

The closest alternative to the Sinn U1 S L is the Fortis Flieger F-41 ($2,530) — common cross-shop and Shared caliber (Sellita SW200-1). If price is the constraint, the Damasko DSub50 covers most of the same brief. From the independents, the CWC Arctic Radar Automatic Diver Watch is the standout microbrand take — common cross-shop and Shared caliber (Sellita SW200-1). Stepping up, the Omega Seamaster Diver 300M Co Axial Master Chronometer 43 5mm ($10,000) is where the same idea goes with a bigger budget.
