Our take on the Longines HydroConquest Negro y Azul 42 mm L3.788.4.90.6

The Longines HydroConquest is a steel dive watch with a black sunray dial, a blue ceramic unidirectional bezel and 300 m water resistance. Its L888 automatic movement uses a silicon hairspring for magnetic resistance and runs up to 72 hours on a full wind. It sits above entry divers like the Seiko Prospex and below the Omega Seamaster, and owners rate the finish and legibility highly for the money. The main trade-offs are its size on smaller wrists and the lack of a quick-release bracelet.

Questions and answers

Is the Longines HydroConquest a true dive watch?
Yes. It is rated to 300 m, has a screw-down crown and a unidirectional rotating bezel, so it meets the requirements for recreational diving.
How does the L888 movement compare with the previous caliber?
The L888 replaced the older L619/888 family with a longer power reserve of up to 72 hours and a silicon hairspring for better magnetic resistance.
Does the 42 mm case fit small wrists?
It is on the large side for wrists under about 6.5 inches. Try it on if you can, or look at the 39 mm version.
Is the bracelet easy to swap?
No. It uses standard spring bars without quick-release pins, so you need a tool to change straps.
What is in the box?
The watch on its steel bracelet, a Longines presentation box and warranty card. No extra strap is included.
