Our take on the Longines HydroConQuest (L3.742.4.56.6)

The Longines HydroConquest L3.742.4.56.6 is a 41mm stainless steel dive watch with a black dial, sapphire crystal, date window and a 300m water rating. It runs on an automatic movement and comes on a steel bracelet with a folding clasp. It sits at the entry point of Swiss dive watches, undercutting the Omega Seamaster and Tudor Black Bay on features-per-dollar while matching them on water resistance. Reviewers rate it as a solid everyday diver, though some find the bracelet and clasp a step behind pricier rivals.

Questions and answers

Is the Longines HydroConquest good for swimming?
Yes. It is rated to 300m with a screw-down crown, so swimming and snorkeling are well within its limits. Rinse it with fresh water after saltwater use.
Does it have a sapphire crystal?
Yes. The crystal is sapphire, which resists everyday scratches far better than mineral glass.
Is the movement automatic?
Yes. It uses a Swiss automatic movement, so it winds itself as you wear it and has a date function. It stops after roughly a day or two off the wrist and needs resetting.
How does it compare with the Tudor Black Bay or Omega Seamaster?
It offers the same 300m rating and sapphire crystal for less, but the bracelet, clasp and bezel finishing are a step below those watches. It is the value pick of the three.
What size is the case?
The case is 41mm across, a mid-size diver that suits most wrists. Try it on if you have a wrist under about 6.5 inches, since the case is fairly thick.
What is in the box?
The watch on its stainless steel bracelet, plus the Longines warranty card and instruction manual. A presentation box is included.
Where is the Longines HydroConQuest (L3.742.4.56.6) cheapest?
At Jomashop, for $1,184.00, 26% under what the other stores charge, as of our latest check.
Where can I buy the Longines HydroConQuest (L3.742.4.56.6)?
