This year, Longines expanded the HydroConquest GMT line with new models featuring 43mm diameter cases. Inspired by the water sports world, they boast water resistance up to 300 metres, robust construction, a unidirectional notched rotating ceramic bezel, a screw-in crown, and a screw-down case back. Like their 41mm counterparts introduced in 2023, the new HydroConquest GMTs are powered by an exclusive Longines movement with multiple time zones and offer a variety of colours and materials.
Designed for those who embrace both performance and style, HydroConquest watches cater to individuals pushing boundaries and seeking new horizons. Initially launched in 2007, the collection expanded last year with a range of 41mm diameter GMT models featuring a fresh design.
Now, the HydroConquest family welcomes new 43mm diameter models in a choice of black, blue, or green dials. Each is equipped with a sapphire crystal featuring a multilayer anti-reflective coating. The arrow-shaped GMT indicator matches the dial decals’ colour. The bezel showcases a 24-hour scale in two tones to denote the transition between night and day. Super-LumiNova-coated indexes ensure easy readability in all conditions, with round indexes at 6 and 9 o’clock and triangular indexes at 12 o’clock. The date is clearly displayed at 3 o’clock.
These stainless-steel cases house the exclusive Longines GMT calibre L844.5, equipped with a silicon balance spring and innovative non-magnetic components featuring alternating polished and satin-brushed surfaces. This movement’s resistance to magnetic fields is ten times more than the ISO 764 reference standard, ensuring extreme precision and a power reserve of up to 72 hours.
The GMT function holds a profound historical significance for Longines, dating back to the brand’s early innovations in timekeeping. In 1908, a model designed for the Ottoman Empire (Turkey) could convert Turkish time into Western time. Three years later, Longines filed a patent for the first pocket watch displaying two time zones.
In 1925, the brand produced its first series of wristwatches displaying a second time zone. Today, flagship models like the Longines Spirit Zulu Time, Longines Master Collection GMT, and the HydroConquest GMT continue this legacy, offering both functionality and elegance to discerning watch enthusiasts. This rich heritage is a testament to Longines’ commitment to innovation and precision, a legacy the watch fans become a part of with the new HydroConquest GMT models.
Available with stainless steel bracelets featuring H-shaped links or blue and black rubber straps, the new HydroConquest GMT models prioritise comfort, with all bracelets featuring a double safety folding clasp with micro-adjustment.
