The short answer

The closest alternative to the Longines HydroConquest 43mm is the Bremont Supermarine 500M ($4,700) — common cross-shop and Pro diver. If price is the constraint, the Hamilton Khaki Navy Frogman Auto at $1,395 (vs $4,700 for the HydroConquest 43mm) covers most of the same brief. From the independents, the Audaz Sea Ranger ADZ-2050 is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Jaeger-LeCoultre Polaris Date Stainless Steel ($11,100) is where the same idea goes with a bigger budget.
