Is the HydroConquest a true dive watch?

Yes. It is rated to 300 m, has a screw-down crown and a unidirectional timing bezel, so it meets the usual dive-watch standard.

How does it compare with the Oris Aquis?

Both are Swiss automatic divers with 300 m ratings. The HydroConquest offers a longer power reserve and a more classic look; the Aquis has a more distinctive case and bracelet design.

What is the power reserve?

The L888 movement runs about 64 hours on a full wind, so it keeps going through a weekend off the wrist.

Yes, there is a date window at 3 o'clock.

The watch on its steel bracelet, with the Longines presentation box and warranty card.

Our take on the Longines Hydroconquest Automatic Black Dial Men's Watch L37814566

The Longines HydroConquest L3.781.4.56.6 is a 41 mm automatic dive watch with a sunray black dial and a yellow-accented unidirectional bezel. It is rated to 300 m, runs on the Longines L888 movement with about 64 hours of power reserve, and has Super-LumiNova on the hands and markers. It suits buyers who want Swiss dive-watch specs and heritage without paying luxury-tier money, and it competes with the Oris Aquis and TAG Heuer Aquaracer on water resistance and finish. Owners praise its build and legibility; some find the case thick and the bracelet clasp basic for the class.

MovementPraisedThe L888 is reported to keep good time, and the long power reserve means it keeps running after a weekend off.
