L3.788.4.09.9Ref

The Longines HydroConquest L3.788.4.09.9, introduced in 2026 in conjunction with the 2026 Commonwealth Games, follows the dial design established by the 2024 HydroConquest GMT. Its round 42mm stainless steel case includes a screw-in crown, unidirectional rotating ceramic bezel, 30 bar water resistance, and a scratch-resistant sapphire crystal with several layers of anti-reflective coating on both sides; the teal polished lacquered gradient dial has applied indexes rather than Arabic numerals, silvered polished hands, and a date. Power comes from the self-winding L888 calibre with monocrystalline silicon balance spring, beating at 25,200 vibrations per hour and offering 72 hours of reserve, driving the central hours, minutes, seconds, and date; it is fitted with a black rubber strap with a double security folding clasp and micro-adjustment.
