The short answer

The closest alternative to the Sinn T50 GBDR is the Sinn EZM 3 S ($3,046) — pro diver and Looks nearly identical. If price is the constraint, the Glycine Combat Sub Box Ceramic at $1,800 (vs $4,428 for the T50 GBDR) covers most of the same brief. From the independents, the Serket Watch Co Reef Mariana is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Rolex Submariner Date ($50,900) is where the same idea goes with a bigger budget.
