New Generation Longines HydroConquest - The Icon Revamped

New Generation Longines HydroConquest. For decades, the Longines HydroConquest has been a gold standard in the world of luxury diving watches. It is the consummate 'go-anywhere, do-anything' timepiece—a rugged tool watch possessing enough Swiss elegance to transition seamlessly from a wetsuit to a business suit.

Today, we are thrilled to welcome a significant evolution of this legendary line. Longines has officially released the new 2026 HydroConquest collection, introducing substantial contemporary overhauls that elevate its aesthetics, ergonomics, and movement technology.

Here is why the new HydroConquest is the must-have dive watch of the year.

Refined Aesthetics: A Cleaner, More Modern Look

The first thing you will notice about the new HydroConquest is its streamlined appearance. The signature, oversized Arabic numerals at 12, 6, and 9 o'clock—a staple of the HydroConquest design for years—have been retired.

They are replaced by highly legible applied geometric indexes. This change creates a more sophisticated and balanced dial layout, moving the HydroConquest toward a more modern and premium aesthetic. The only exception remains at 3 o'clock, which is occupied by a refined date window.

The bidirectional bezel has also received an upgrade. It still features a lustrous, scratch-resistant ceramic insert, but it now has a re-engineered design with a new, more legible font.

New Versatility: 39mm Case & Mesh Bracelet

In a move that will delight watch enthusiasts, Longines is now offering the HydroConquest in two case sizes: the standard 42mm and an all-new, highly requested 39mm option.

Both case sizes feature a thinner profile compared to previous generations, enhancing wearability. They arePredominantly brushed with polished accents, retaining the collection’s classic 300-meter water resistance.

Furthermore, Longines has introduced a stunning new tapered Milanese steel mesh bracelet option. This bracelet turns the HydroConquest from a pure tool watch into something exceptionally elegant, perfect for dressing up any occasion. The mesh bracelet joins the updated H-link bracelet, both of which now come equipped with tool-less micro-adjustment clasps for the perfect fit.

The Heart: Silicon Technology and High Antimagnetism

While the aesthetic changes are compelling, the most substantial upgrades lie within the case. The new HydroConquest models are powered by the Calibre L888.5, a movement exclusive to Longines.

This self-winding movement is a powerhouse, offering a respectable 72-hour power reserve (three full days).

Most importantly, the L888.5 is highly resistant to magnetic fields. It achieves this resilience through the use of a silicon balance-spring. Because silicon is insensitive to magnetic forces, this watch is immune to the effects of everyday magnetic sources (like smartphones, tablets, and magnetic handbag clasps) that can cause standard mechanical watches to run inaccurately.

In fact, the new HydroConquest has antimagnetic resistance that far exceeds the ISO 764 standard, making it one of the most resilient luxury dive watches in its class. Because of this durable technology, Longines offers a comprehensive 5-year warranty on all models fitted with a silicon balance-spring.
