Launched in 2025, the Longines PrimaLuna L8.124.0.71.6 is a stunning addition to the PrimaLuna series, distinguished by its elegantly rounded case complemented by intricate aesthetic details. The watch boasts a 34.00 mm stainless-steel case embellished with 58 Top Wesselton IF-VVS diamonds, which weigh in total 0.580 carats. It's protected by a scratch-resistant sapphire crystal that has a multi-layer anti-reflective treatment on both surfaces, ensuring clarity and resilience against water up to 3 bar (30 meters). Its total weight is around 101 grams.

The dial, crafted in a sunray silver finish, features painted Roman numerals and exquisite blued-steel hands shaped like leaves. A date display at the 3 o'clock position enhances its functionality. At the heart of the watch lies the Longines caliber L888, a self-winding mechanical movement that operates at 25,200 vibrations per hour (3.5 Hz) and offers a power reserve of roughly 72 hours. This movement incorporates a monocrystalline silicon balance spring and provides comprehensive timing functions, including hours, minutes, seconds, and date. Completing the timepiece is a stainless-steel bracelet secured with a triple-safety folding clasp that has a push-piece opening mechanism.
