Product description

The Longines HydroConquest L3.742.4.56.6 represents the perfect blend of sporty durability and Swiss elegance. Designed for men who demand both style and high-level functionality, these diving watches are built for everyday adventures and underwater challenges.

The 41 mm round stainless steel case ensures robustness and a bold presence, while the black analog dial with luminescent hands and markers guarantees perfect legibility in low-light conditions. The unidirectional rotating bezel made of aluminum and steel is essential for precise underwater timing.

Powered by a mechanical movement with automatic winding, the watch delivers reliable performance without the need for a battery. Its water resistance of 30 ATM (300 meters) confirms its suitability for professional diving, and the sapphire crystal with anti-reflective coating ensures excellent scratch resistance.

The silver-tone stainless steel bracelet features a folding clasp for secure wrist fit. A date display at 3 o’clock adds daily practicality.

The HydroConquest is the ideal companion for both everyday wear and demanding environments, combining technical precision, sporty energy, and timeless design.
