Our take on the Longines HydroConquest Stainless Steel Sunray Blue Dial Automatic Diver's L3.780.4.96.6 300M Men's Watch

The HydroConquest 39 is Longines' compact dive watch, with a 300 m rating, a ceramic bezel and a sunray blue dial. Its L888 automatic movement runs about 72 hours on a wind, well beyond the roughly 38 to 40 hours of a standard Sellita or ETA diver. At 39 mm wide and 12.2 mm thick it wears smaller than most 41 to 43 mm divers, which suits wrists that find those too bulky. Against the Tudor Black Bay and Oris Aquis it gives up some finishing and brand cachet but matches them on water resistance and beats most on power reserve.

Best forSmall to medium wrists wanting a real dive watchDaily wear that sees water and saltBuyers who want Swiss automatic with a long weekend-proof reserveFirst serious dive watch
Pros
  • 39 mm case wears comfortably and fits under a cuff
  • 300 m water resistance with screw-down crown and case back
  • Ceramic unidirectional bezel resists scratches and fading
  • L888 movement with about 72 hours of power reserve
  • Sapphire crystal with anti-reflective coating on both sides
  • Sunray blue dial shifts from bright to near-navy in light
Cons
  • Bracelet clasp lacks a quick micro-adjust and on-the-fly extension
  • No helium escape valve, unlike some deeper-rated rivals
  • Date window at 3 cuts into the dial symmetry for some
  • Lume is good but not class-leading next to Seiko divers

Questions and answers

Is the 39 mm HydroConquest too small for a man?
It depends on wrist size. At 39 mm it suits wrists under about 7 inches well and still looks like a dive watch. Larger wrists may prefer the 41 mm version.
How does it compare with the Tudor Black Bay 58?
Both are compact Swiss divers with 300 m and 39 mm cases. The Tudor has a more refined bracelet and movement finishing; the Longines offers a ceramic bezel and a longer power reserve for less outlay.
Can I swim and dive with it?
Yes. It is rated to 300 m with a screw-down crown and case back, which covers swimming, snorkeling and recreational diving. Have it pressure-tested after any service or hard knocks.
How long does it run without wearing it?
The L888 movement has about 72 hours of power reserve, so it keeps time through a weekend off the wrist. Wind it about 30 turns to restart after longer storage.
Does it have a ceramic bezel?
Yes, the unidirectional rotating bezel is ceramic, which resists scratches and fading better than aluminum inserts.
What is in the box?
The watch on its steel bracelet, the Longines presentation box and paperwork. It does not include a spare strap or a travel case.
