Longines Conquest Sunray Blue Dial Men 41mm L38304929

Combining high-performance sports engineering with modern Swiss design, the Longines Conquest Automatic 41mm L38304929 delivers a dynamic, contemporary statement in everyday luxury wristwear. Sculpted in a tailored 41.00 mm surgical-grade 316L stainless steel case measuring an ultra-sleek 10.90 mm in profile, this versatile timepiece features a smooth fixed polished steel bezel that frames an evocative sunray blue dial. The dial face is detailed with a circular-grained snailed chapter ring, applied silver-polished baton indices, faceted hands inlaid 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 driven 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 blue textured rubber strap secured by a double-safety folding clasp with push-piece micro-adjustment, it is water-resistant 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 unveiled in 1954 as Longines' first officially registered collection protected by the Swiss Federal Intellectual Property Office, the Conquest line embodies endurance, performance, and everyday elegance. Reference L3.830.4.92.9 represents the modern evolution of this sporting icon, pairing a refined 41.00 mm diameter with a slim 10.90 mm case height and a compact 49.10 mm lug-to-lug profile. The case architecture combines vertical satin-brushed case flanks with high-polished chamfers along the bezel and lugs, creating fluid visual continuity that transitions directly into the integrated strap.

Sunray Blue Depth & Concentric Dial Architecture

The dial balances understated luxury with functional instrument clarity. The central disc features a radial sunburst finish that reflects changing light across bright ocean-blue and deep navy shades. Framing the center is a finely grooved, snailed circular track that anchors the applied polished baton indices, adding architectural depth and clear visual hierarchy. Silver-polished baton hands and faceted indices are generously treated with Swiss Super-LumiNova for intuitive time-telling day or night, while the date aperture at 6 o'clock preserves the dial's vertical symmetry.

Calibre L888.5 Silicon Precision & Ergonomic Rubber Strap Engineering

Operating at the heart of the timepiece is the Longines Calibre L888.5 automatic mechanical movement. Beating 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. The movement incorporates an anti-magnetic monocrystalline silicon balance spring, rendering it impervious to magnetic disturbances from mobile devices, laptops, and travel gear. Paired with a high-grade textured blue rubber strap, the watch features a double-safety folding clasp with an integrated micro-adjustment slider, allowing effortless fine-tuning of strap tension to accommodate natural wrist expansion in warmer climates.
