For over a century, Longines has been a leading manufacturer of luxury watches, with a rich history and a reputation for quality craftsmanship. The company's HydroConquest collection is a testament to this commitment to excellence, offering a range of timepieces that are both stylish and functional. Designed for those who lead active lifestyles, the HydroConquest is a perfect companion for the modern explorer.

The HydroConquest collection takes its inspiration from the world of water sports. The watches in this collection are water-resistant to a depth of 300 meters, making them suitable for swimming, diving, and other water activities. Their robust construction and unidirectional rotating bezels make them ideal for those who need a reliable and functional timepiece.

In 2023, Longines introduced the HydroConquest GMT, a new addition to the collection that features a GMT complication. This complication allows the watch to track two time zones simultaneously, making it a perfect choice for travelers and those who work with people in different parts of the world. The HydroConquest GMT is available in a variety of colors, including green, black, and blue. The 43mm stainless steel case gives the watch a substantial and masculine look, while the polished ceramic bezel adds a touch of sophistication.

The watch in the image appears to be the 43mm HydroConquest GMT with a green sunray dial. The sunray finish catches the light and creates a dynamic effect on the dial, while the green color gives the watch a modern and stylish look. Watch collectors would likely appreciate the use of a ceramic bezel over a traditional aluminum bezel. Ceramic bezels are more scratch-resistant and fade-resistant than aluminum bezels, making them a better choice for those who wear their watches in harsh conditions.

The watch hands and hour markers are coated with Super-LumiNova, a luminescent material that allows the watch to be read in low-light conditions. The screw-down crown and case back help to ensure that the watch is water-resistant to its rated depth. The bracelet is made of stainless steel and features a double security folding clasp with a micro-adjustment system. This clasp ensures that the watch stays on your wrist securely, even during strenuous activity.

Longines takes pride in the exclusive L844 automatic movement that powers the HydroConquest GMT. It's more than just a pretty collection of gears – this movement boasts several noteworthy features that make it a worthy companion for globetrotters and those living life across multiple time zones.

Firstly, the L844 has an impressive power reserve of 72 hours. Picture this: you take off your watch on a Friday evening and put it back on come Monday morning, and it'll still be ticking accurately. This extended power reserve eliminates the hassle of daily winding, especially for those with a busy lifestyle.

Secondly, the GMT complication is a practical tool for many. The watch's additional GMT hand, often in a contrasting color, independently tracks a second time zone. This means you can see both your local time and the time in another location with just a glance. Whether you're a frequent flyer coordinating international meetings or someone who simply loves keeping track of a loved one living abroad, the practicality of the GMT function is a true winner for a modern lifestyle.

Longines' commitment to precision is evident in the movement's use of a silicon balance spring. Silicon is a high-tech material that boasts several advantages. Unlike traditional metal components, silicon is resistant to corrosion, temperature changes, and most importantly, magnetic fields. With the ever-increasing presence of electronics around us, anti-magnetic properties ensure your watch keeps time accurately, no matter where your day takes you.

The L844 movement operates at 25,200 vibrations per hour. It may sound technical, but this high beat rate contributes to the watch's smooth and precise movement of the second hand. Every little detail matters in Longines' pursuit of accuracy.

Of course, Longines has put just as much thought into the watch's practical usability as they have into its inner workings. The screw-down crown ensures a tight seal and contributes to the watch's impressive 300-meter water resistance. Whether you're a casual swimmer or an avid diver, the HydroConquest GMT has the resilience to be your aquatic partner. The unidirectional rotating bezel is marked in clear graduations, making it a valuable tool for tracking elapsed time during underwater sojourns.

For everyday wear, the stainless steel bracelet comes equipped with a double security folding clasp and a micro-adjustment system. This ensures that the watch stays securely on your wrist while allowing precision adjustments for a perfect fit. From rugged expeditions to busy commutes, the Hydroconquest GMT is designed for comfort, just as much as precision and durability.

The addition of Longines' in-house GMT movement to the robust and capable HydroConquest platform is a testament to the brand's versatility. It shows they're not a one-trick pony – rather, they're a team dedicated to making watches that are as functional as they are refined. The HydroConquest GMT isn't just a watch, it's a practical tool made with adventurers in mind, whether they're boardroom jetsetters or weekend wanderers.
