Water never sleeps. And neither does the HydroConquest.

Since 2007, this collection has defined what a dive watch can be: precise beneath the surface, elegant above it, reliable for a lifetime. In 2026, Longines took a step that enthusiasts had been waiting three years for — and the result exceeded every expectation.

The third generation of the HydroConquest is not an evolution. It is a rewrite from the very first page.

Form That Respects Substance

There are watches that shout. And then there are watches that speak quietly — and say more. The new Longines HydroConquest belongs to the second category.

It is slimmer, cleaner and more composed than ever before. A profile of just 11 mm places it among the most elegant dive watches in its class. You feel it the moment it sits on your wrist. It disappears beneath a shirt cuff without sacrificing a single millimetre of performance.

The brushed stainless steel case carries all the hallmarks of a serious diving instrument: screw-down crown, sapphire crystal with double-sided anti-reflective coating, 300 metres of water resistance. The crown guards have been reworked — less prominent, more fluid, more natural. The watch feels less militant and more like a part of everyday life.

Exactly as it should be.

A Dial That Finally Breathes

The previous generation of the HydroConquest carried Arabic numerals on its dial — bold, legible, functional. They served their purpose. But the new generation asked for more.

The numerals are gone, and space has taken their place. Applied geometric indices — batons, triangles, circles — filled with Super-LumiNova give the dial a clarity that works equally well forty metres beneath the surface as it does at a business lunch. The Longines logo is now applied rather than printed — a detail that elevates the watch by an entire tier, without anyone being able to say exactly why.

The result is a dial that looks as though it belongs on a watch costing twice as much. And yet it is still the HydroConquest — no show, only substance.

A ceramic bezel in five colours — black, blue, slate grey, deep green and frosted blue — allows every wearer to find their own version of this watch. Every combination of dial and bezel tells a different story. Every story is equally compelling. And behind each one stands what Swiss watchmaking does best: precision that never puts itself on display.

The Collection's New Voice: The Mesh Bracelet

There are new features that please. And then there are new features that change the entire character of something.

For the first time in the history of the HydroConquest, Longines introduces a Milanese mesh bracelet. Not a cheap imitation that stretches and loses its shape within a year. Brushed steel with polished edges, removable links, a double-button folding clasp, a built-in micro-adjustment system. A bracelet that sits on the wrist as though made to measure — because in essence, it is.

Where the steel H-link bracelet emphasises the strength and precision of a diving instrument, the mesh bracelet brings lightness. Airiness. An entirely different story on the wrist.

Morning by the sea — H-link. Evening in the city — mesh. One watch. Two characters. One decision.

A Movement That Works for You

Inside every HydroConquest 2026 beats Calibre L888.5 — an automatic movement produced exclusively for Longines. A silicon balance spring delivers ten times the resistance to magnetic fields required by ISO 764 standard. In a daily life full of phones, computers and magnetic clasps, that is not a luxury — it is a necessity.

A 72-hour power reserve means three days without winding. Take them off on Friday evening, put them back on Monday morning — and they are still running. No worries. No rituals. Only precision, quiet and tireless, hidden behind a dial that deserves it no less than it deserves the dial.

Twelve References. One Philosophy.

The third generation of the HydroConquest arrives in twelve references — six configurations, two sizes. 39 mm for those who prefer a watch that disappears on the wrist. 42 mm for those who want presence.

Both sizes share the same profile, the same movement, the same philosophy. They differ only in how loudly they speak.
