Longines Conquest Grey Dial Men 42mm L38364529

Exemplifying Swiss precision engineering and contemporary sports-luxe elegance, the Longines Conquest Automatic Chronograph 42mm L38364529 delivers a commanding, versatile statement in high-performance masculine watchmaking. Encased in an assertive 42.00 mm surgical-grade 316L stainless steel case crowned by a fixed ceramic bezel with an engraved tachymeter scale, this timepiece bridges dynamic athleticism with sophisticated tailoring. The dial showcases a radiant sunray anthracite-grey finish accented by three contrasting snailed chronograph subdials, applied silver-polished indices, faceted hands inlaid with Swiss Super-LumiNova, and a scratch-resistant sapphire crystal with multi-layered anti-reflective coating on both sides. Driven by the in-house Longines Calibre L898.5 self-winding mechanical chronograph movement—engineered with an anti-magnetic monocrystalline silicon balance spring and delivering an extended 59-hour power reserve—it is pressure-tested to 100 metres (10 ATM) and mounted on an ergonomic rubber strap secured by a double-safety folding clasp with fine micro-adjustment, backed by Longines’ extended 5-year international manufacturer warranty.

Design & Craftsmanship

Sports-Luxe Heritage & The 42mm Conquest Chronograph Architecture

Originally introduced in 1954 as Longines' first watch line to receive protected naming rights, the Conquest family represents the brand's spirit of performance and endurance. Scaled to a contemporary 42.00 mm diameter with a 14.30 mm case height, reference L3.836.4.52.9 delivers athletic visual impact without sacrificing wearability. The circular case features alternating vertical satin-brushed planes and mirror-polished chamfers, flowing into contoured lugs that integrate seamlessly with the strap. Flanking the screw-down crown are ergonomic pump-style pushers that provide tactile feedback when activating, stopping, and resetting the chronograph mechanism.

Anthracite Sunray Depth & High-Tech Ceramic Bezel

The dial balances high-contrast instrument legibility with understated luxury. Finished in a rich sunray anthracite grey, the dial surface captures ambient light in shifting radial arcs. Three recessed subdials organize timing functions: a small running seconds register at 3 o'clock, a 12-hour counter at 6 o'clock, and a 30-minute counter at 9 o'clock. Applied polished silver-toned hour markers and broad baton hands are generously treated with Swiss Super-LumiNova for swift low-light reading. Framing the crystal is a fixed bezel with a high-gloss ceramic insert, ensuring the tachymeter scale remains scratch-free through years of active wear.

Calibre L898.5 Precision & Silicon Regulating Organ

Beneath the dial beats the Longines Calibre L898.5 automatic mechanical chronograph movement. Operating at 28,800 vibrations per hour (4 Hz) across 37 synthetic rubies, it delivers up to 59 hours of autonomous power reserve. The calibre incorporates a state-of-the-art monocrystalline silicon balance spring, making the regulating organ impervious to everyday magnetic fields (from laptops, mobile devices, and magnetic closures) while enhancing resistance to temperature variations. The finely finished movement—adorned with circular graining and Côtes de Genève stripes—is visible through the sapphire exhibition case back.
