How this list is built

Candidates are every dive watch in the catalogue with a verified Amazon price band under $1,000. Each is scored against the Longines HydroConquest Automatic on the maker's published figures only: the same movement family (mechanical or quartz) scores highest, then water resistance at or above the HydroConquest Automatic's rating, then a case within two millimetres, then a matching crystal material. We do not test watches, and we do not rate resemblance. Prices are shown as bands, never exact figures, because they change daily.
