Longines Conquest Sunray Blue Dial Men 41mm L38304976

Merging high-performance sports-luxe engineering with high-jewelry brilliance, the Longines Conquest Automatic 41mm L38304976 delivers an opulent, versatile statement in contemporary Swiss watchmaking. Sculpted in a tailored 41.00 mm surgical-grade 316L stainless steel case measuring an ultra-sleek 10.90 mm in profile, this refined timepiece is crowned with a smooth fixed polished steel bezel that frames a radiant sunray blue dial. The dial face is illuminated by 15 Top Wesselton VS-SI brilliant-cut diamond hour markers totaling 0.064 carats, complemented by silver-polished baton hands treated with Swiss Super-LumiNova and an unobtrusive date aperture positioned at 6 o'clock. Protected by a scratch-resistant sapphire crystal with multi-layered anti-reflective coating on both faces, it is powered by the in-house Longines Calibre L888.5 automatic mechanical movement. Engineered with an anti-magnetic monocrystalline silicon balance spring, this high-precision calibre provides an extended 72-hour power reserve visible through a transparent exhibition case back. Mounted on an articulated 316L stainless steel bracelet with a triple-safety folding deployant clasp, it is pressure-tested to 100 metres (10 ATM) and backed by Longines’ comprehensive 5-year international manufacturer warranty.

Design & Craftsmanship

Modern Sports-Luxe & The 41mm Conquest Architecture

First registered in 1954, the Conquest line stands as Longines’ defining sports-elegance platform. The modern 41.00 mm reference L3.830.4.97.6 evolves the classic sports watch into an elevated luxury timepiece. With an ultra-slim case thickness of 10.90 mm and a compact 49.10 mm lug-to-lug profile, the watch rests flush and centered across the wrist. The circular 316L stainless steel case features vertical satin brushing along the flanks contrasted by high-polished bevels, transitioning smoothly into the solid end-links of the bracelet. The fluted screw-in crown is flanked by streamlined crown guards, providing robust protection while maintaining an uncluttered dress profile.

Sunray Blue Depth & Diamond Radiance

The dial balances intense chromatic depth with fine-jewelry sparkle. Treated with a fine radial sunburst finish radiating outward from the center, the blue dial surface catches changing light in luminous arcs. It is illuminated by 15 Top Wesselton VS-SI natural diamonds individually mounted in polished chatons, featuring a double-stone setting at 12 o'clock. Polished silver-toned baton hands treated with Swiss Super-LumiNova sweep gracefully across the dial, while a framed date aperture at 6 o'clock preserves the watch's vertical symmetry.

Calibre L888.5 Silicon Precision & 72-Hour Power Reserve

At the heart of the timepiece is the Longines Calibre L888.5 automatic mechanical movement. Operating at an optimized frequency of 25,200 vibrations per hour (3.5 Hz) across 21 synthetic jewels, it generates an autonomous power reserve of up to 72 hours—allowing the watch to be put aside over the weekend and picked up on Monday morning fully wound. The movement is fitted with an anti-magnetic monocrystalline silicon balance spring, rendering the regulating organ immune to magnetic interference from smartphones, laptops, and travel accessories. Through the transparent sapphire exhibition case back, enthusiasts can admire the Côtes de Genève finishing, perlage, and skeletonized oscillating weight.
