The Longines PrimaLuna Moonphase (Ref. L8.126.4.97.6) debuted in 2025 as a radiant interpretation of the PrimaLuna collection, uniting its signature rounded silhouette with the romance of a moon phase display. This model epitomizes Longines’ dedication to timeless design, refined proportions, and precise Swiss craftsmanship. The 34 mm stainless-steel case, measuring 11.60 mm in thickness and 41.00 mm lug to lug, showcases polished finishing for a fluid, luminous appearance. A scratch-resistant sapphire crystal with multi-layer anti-reflective coating on both sides ensures excellent legibility, while a transparent sapphire-crystal case back reveals the automatic movement within. The watch is water-resistant to 3 bar (30 meters) and weighs approximately 110 grams. The blue mother-of-pearl dial, shimmering with natural iridescence, is adorned with diamond-set hour markers and features a moon phase aperture at 6 o’clock framed by an integrated pointer date scale. The rhodium-plated leaf-shaped hands add a subtle metallic contrast against the dial’s depth and color. At its core, the Longines Caliber L899 - based on the ETA A31.L91 - operates at 25,200 vibrations per hour (3.5 Hz) with a 72-hour power reserve. It powers hours, minutes, seconds, date, and moon phase functions with refined precision. The stainless-steel bracelet with a triple-safety folding clasp and push-piece opening mechanism completes the design, making the PrimaLuna Moonphase L8.126.4.97.6 a brilliant embodiment of celestial beauty and mechanical artistry.
