Longines has announced that they will be releasing an all ceramic timepiece that may well be a viable option for many horologists. At first glance this comes across as a simple offering, but let’s take a closer look at the “Longines HydroConquest Full Ceramic”.


Last year Longines released the “HydroConquest” with a ceramic bezel in several color options in a collection you can check out here. Now they’ve gone all the way by making an all ceramic version. It is the main theme and distinguishing factor in this timepiece, which has even been highlighted on the dial by indicating the chemical composition of this particular case material.

A exact retail price has not yet been set for this watch, but we suspect that it will carry an accessible price-tag. It may well become an excellent entry level-ceramic watch, if priced competitively against the other existing options. Longines has managed to successfully combine their technical excellence, while drawing inspiration from the world of aquatic sports and still providing an appealing sporty look.


The 43mm case is made of black ceramic with a polished finish and solid case back. On the flip-side we encounter a circular and matte finish engraved with some technical details, as well as the image of an “hourglass with wings”. Mounted to the case is a ceramic unidirectional rotating bezel.


It comes equipped with a screw-in crown that is found between robust crown guards. By all means this timepiece has been designed to preserve the traditional style of diving watches, while also being constructed with the essential modern features that consumers would expect from a reputable diver watch. All topped by a sapphire crystal with several layers of anti-reflective coating, which also assists with water-resistance on this watch reaching up to 300 meters (984 feet).


Time is exhibited on a black matte dial with large white round cabochon-style hour index markers, smaller white printed minute markers and the metal applied Arabic numerals 6, 9 and 12. These numerals and markers have been slightly raised to provide a unique subtle visual effect. There is also a white date aperture within a white outlined box at the 3 o’clock position.

On the upper-half of the dial is the “Longines logo”, while on the lower-half we can see them proudly display their ceramics chemical composition “ZrO2”. The central stainless-steel hands, Arabic numerals and hour index markers have all been fitted with a luminescent filling, for an enhanced legibility.
