Every brand needs a reliable dive watch.
For Longines, the Hydroconquest has been this model since 2007. With a stainless steel case, water resistance up to 300 meters, a legible dial, and a unidirectional bezel, these are the basic characteristics of this line. In 2026, the brand introduced an updated version of the Hydroconquest with a new design, sizes, and an elegant bracelet, making the watch more modern and comfortable.
Longines is known for its elegance at a reasonable price, and the new changes to the Hydroconquest highlight just that. Despite retaining all technical and durability characteristics, the watch now boasts a more refined style and appeal.
Case: New Sizes and Thoughtful Design
What's new in the case? The line retains the proven 42 mm size, which is still in demand, but now includes a 39 mm option - more versatile and comfortable for those with smaller wrists. The case thickness for both versions is the same - 11.7 mm, which visually makes the larger model more graceful.
The case is fully matte with a satin finish - an optimal solution for tool watches, reducing glare and emphasizing functionality. The lugs are thin and smoothly curve to the wrist, being an integral part of the design. The screw-down case back is adorned with an engraving of a planisphere and the trademark Longines winged logo. Water resistance of 300 meters is ensured by this case back fixing and the screw-down crown.
Five bezel color options are available: blue, black, green, gray, and bright blue. The bezel is made of ceramic, which guarantees wear resistance. The font of the numbers on the bezel has become thinner and more readable - the trend for minimalism is evident in all details.
Dial: Simplified yet Functional Design
Depending on the case size, four dial options are available:
- Lacquered blue
- Lacquered black
- Lacquered green
- Light blue with a matte sunray effect
The light blue shade is likely achieved through galvanization, giving it depth and a slight metallic sheen. The lacquered dials retain color richness.
The dial design reflects a simplification similar to the Hydroconquest GMT: large Arabic numerals are replaced by 11 applied rhodium hour markers filled with Super-LumiNova for excellent visibility in the dark. Reducing the number of elements and text enhances readability and functionality, and the diamond-shaped hour hand and sword-shaped minute hand glide smoothly over the dial.
The date window is located at the 3 o'clock position. In this case, it is harmoniously integrated into the design and does not disrupt the dial's integrity, adding a useful function.
Bracelets: Classic and Novelty
The new collection features two bracelet options:
- H-Link stainless steel bracelet, already familiar from the Hydroconquest GMT 2023 model. A reliable and familiar solution for dive watches with 300 m water protection.
- New Milanese mesh stainless steel bracelet, adding extra elegance to the watch. This woven bracelet is challenging to reproduce with such quality, making it a premium element of the collection.
Switching to the Milanese bracelet costs an additional 200 USD, justified by the improved look and comfort. Despite its elegance, the bracelet remains quite sturdy and strong, maintaining the model's sporty character. Both bracelets feature micro-adjustment in the clasp for comfortable wear throughout the year.
Movement: Updated Caliber L888.5
Inside the watch is the updated caliber L888.5, which Longines has been using for several years. It has a power reserve of 72 hours and enhanced anti-magnetic protection thanks to a silicon balance spring and other innovative components. The new version of the movement withstands magnetic fields 10 times stronger than ISO 764 standards require.
The self-winding movement is exclusive to Longines, based on the ETA caliber developed by a group subsidiary.
Conclusion: Evolution Without Compromise
The Hydroconquest update exemplifies how small changes elevate the model's status and versatility. The addition of a smaller 39 mm case broadens the audience, while the Milanese bracelet attracts those who prefer elegance and comfort for everyday wear. Meanwhile, all the key characteristics of a reliable diving tool are preserved.
These watches are suitable for both active leisure and office environments, making them a versatile choice in the modern world.
