The closest alternative to the Citizen Promaster Professional Diver is the Citizen Brycen ($394) — pro diver and Looks nearly identical. If price is the constraint, the Casio MDV-106 Duro at $85 (vs $296 for the Promaster Professional Diver) covers most of the same brief. From the independents, the CWC (Cabot Watch Company) Automatic Divers Watch Mk.2 Black with Date is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Tissot Seastar 1000 ($515) is where the same idea goes with a bigger budget.
