The Longines HydroConquest L3.788.4.06.6 combines the unmistakable character of a professional diving watch with the refined aesthetics of Swiss watchmaking. Its 42 mm stainless steel case and green ceramic unidirectional rotating bezel create a bold, contemporary appearance, while the polished green lacquered dial adds depth and elegance. Designed for those who appreciate both performance and sophisticated style, this model is a distinctive member of the HydroConquest collection.

At its heart is a self-winding mechanical movement with a monocrystalline silicon balance spring, beating at 25,200 vibrations per hour and offering an impressive power reserve of up to 72 hours. The practical date display complements the precise mechanical engineering, delivering reliability and convenience for everyday wear.

Built to perform underwater, the watch features a screw-in crown, a screw-down caseback and impressive 300-metre water resistance (30 bar). The scratch-resistant sapphire crystal, enhanced with several layers of anti-reflective coating on both sides, ensures excellent visibility and protection. Swiss Super-LumiNova on the hands and indices supports readability in low-light conditions.

The stainless steel bracelet completes the design, featuring a double-security folding clasp with a micro-adjustment system for a secure and comfortable fit. The Longines HydroConquest L3.788.4.06.6 is an ideal choice for those seeking a premium Swiss automatic diving watch that combines technical capability, distinctive green styling and timeless versatility.
