In 2025, the Longines PrimaLuna Moonphase L8.126.4.97.6 joined the PrimaLuna collection, blending the line's characteristic rounded form with a moon phase display. The 34.00 mm stainless-steel case (11.60 mm thick, 41.00 mm lug-to-lug) is fitted with a scratch-resistant sapphire crystal with double-sided multi-layer anti-reflective coating and a sapphire case back, while water resistance stands at 3 bar (30 m). The blue mother-of-pearl dial features diamond hour markers and a moon phase aperture at 6 o'clock with an integrated date pointer, rhodium-plated leaf hands, and is powered by the automatic L899 caliber (25,200 vph, ~72h reserve, based on ETA A31.L91) for hours, minutes, central seconds, pointer date, and moon phase; the watch weighs about 110 grams on a stainless-steel bracelet with a triple-folding safety clasp.
