Our take on the Longines Hydroconquest (L3.781.3.58.7)

The Longines HydroConquest L3.781.3.58.7 is a 41mm stainless steel dive watch with a black dial, sapphire crystal and a 300m water rating. It runs on an automatic movement with a date window and a steel bracelet with a folding clasp. It sits above entry divers like the Seiko Prospex and Tissot Seastar on finishing and brand heritage, but below luxury divers such as the Omega Seamaster. It suits buyers who want a serious Swiss diver without paying luxury-tier money.

Questions and answers

Is the Longines HydroConquest a true dive watch?
Yes. It has 300m water resistance, a screw-down crown and a rotating dive bezel, so it is rated for recreational diving.

Yes, the crystal is sapphire, which resists scratches better than mineral glass.

The case is 41mm in diameter, which suits most wrists but can feel large on slim ones.
