Longines Conquest Blue Sandblasted Dial Men 41mm L38604926

Combining robust sports-luxe engineering with timeless Swiss sophistication, the Longines Conquest Automatic 41mm L38604926 represents the modern evolution of Longines' legendary everyday sports watch. Sculpted in a refined 41.00 mm surgical-grade 316L stainless steel case measuring a slender 10.90 mm in profile, this versatile timepiece features a smooth fixed polished steel bezel that frames an evocative sunray blue dial. The dial surface is accented by a circular-grained snailed hour track, applied silver-polished baton indices, faceted hands treated with Swiss Super-LumiNova, and a balanced date aperture positioned at 6 o'clock. Protected by a scratch-resistant sapphire crystal with multi-layered anti-reflective coating on both sides, it is powered by the in-house Longines Calibre L888.5 self-winding mechanical movement. Fitted 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 integrated 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

Introduced originally in 1954, the Conquest line stands as Longines’ defining sports-elegance platform. The redesigned 41.00 mm reference L3.860.4.92.6 updates the classic tool watch into a sleek, go-anywhere dress-sports timepiece. With a case thickness of just 10.90 mm and a compact lug-to-lug span under 49.00 mm, the watch rests low and flush against the wrist. The case geometry features fluid polished bevels along the flanks that contrast against vertical satin-brushed surfaces, flowing seamlessly into the solid end-links of the bracelet.

Sunray Blue Depth & Concentric Dial Architecture

The dial balances understated luxury with functional instrument clarity. The central disc is treated with a radial sunburst finish that reflects changing light across vibrant ocean-blue and deep navy shades. Surrounding the center is a finely grooved, snailed circular track that anchors the applied polished baton indices, creating visual depth and architectural hierarchy. The silver-polished baton hands and faceted markers are filled with Swiss Super-LumiNova for intuitive time-telling day or night, while the date window at 6 o'clock preserves the dial'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), it delivers an impressive 72-hour power reserve—allowing the watch to be set down over a weekend and picked up on Monday morning without missing a beat. The movement incorporates an anti-magnetic monocrystalline silicon balance spring, rendering it resistant to magnetic fields from mobile phones, laptops, and travel accessories. Through the screw-down exhibition case back, collectors can view the Côtes de Genève finishing, perlage, and skeletonized winding rotor bearing the Longines winged hourglass.
