April 2026 Longines HydroConquest Automatic 39mm – Full Set

Reference: L3.779.4.06.6

A superb example of the newly updated Longines HydroConquest, featuring a beautifully rich green lacquered dial and matching green ceramic bezel.

At 39mm, this is arguably the sweet spot within the HydroConquest collection—substantial enough to retain the character of a proper sports watch while remaining comfortable and well proportioned on most wrists.

Dating from April 2026, this exceptionally recent example is supplied as a complete set with its original Longines presentation box, warranty card, paperwork and accompanying accessories. The watch benefits from the balance of Longines’ five-year international manufacturer’s warranty, running until April 2031.

Powering the watch is the Longines calibre L888 automatic movement. Featuring a monocrystalline silicon balance spring and an impressive power reserve of up to 72 hours, it offers dependable modern performance alongside traditional Swiss mechanical watchmaking.

The polished green dial is complemented by applied hour markers, bold luminous hands and Swiss Super-LumiNova®, ensuring excellent legibility in both daylight and low-light conditions. A practical date window is positioned at three o’clock.

Its stainless-steel case is fitted with a scratch-resistant sapphire crystal with anti-reflective coating on both sides. A screw-down crown, screw-down case back and 300-metre water resistance make this a genuinely capable sports and diving watch rather than merely a dive-inspired design.

Completing the watch is its original stainless-steel bracelet with a double-security folding clasp and convenient micro-adjustment system.

With a current Longines retail price of £1,595, this nearly new full-set example represents an excellent opportunity to acquire one of the most versatile models in the modern Longines collection.
