Longines Conquest Automatic Sunray Black Dial with Swiss Super-LumiNova® Black Rubber Strap 38 mm [L3.720.4.52.9]

The Longines Conquest [L3.720.4.52.9] Automatic is a compelling expression of sport-elegance and Swiss mechanical craftsmanship. Encased in a distinctive 38 mm stainless steel case, this model features a sunray black dial enhanced with Swiss Super-LumiNova® on its hands and applied indices for excellent legibility — maintaining a sleek and refined profile with practical functionality. 

Powered by a self-winding mechanical movement, this timepiece beats at 25,200 vibrations per hour and incorporates a monocrystalline silicon balance-spring, delivering a power reserve of up to 72 hours — a benchmark of Longines’ mechanical reliability. 

The dial is protected by a scratch-resistant sapphire crystal with multiple layers of anti-reflective coating, providing clarity in diverse lighting conditions. Designed for active wear, the watch includes a date display and a screw-in crown, with water resistance to 10 bar (100 m). 

Completing this sporty and versatile aesthetic is a black rubber strap, secured by a double security folding clasp with micro adjustment system, offering both comfort and confidence on the wrist.
