The Longines Master Collection L2.449.5.87.7, launched in 2026, represents an evolution within the Master Collection series. This version maintains the essential design elements that have characterized the line but brings enhancements in its case proportions and dial details, contributing to a more modern and defined look. It features a round stainless steel case with yellow gold accents, protected by a sapphire crystal treated with multiple layers of anti-reflective coating on both sides, and offers water resistance up to 30 meters.

The watch showcases a white mother-of-pearl dial adorned with diamond hour markers, with a total of 11 Top Wesselton VS-SI diamonds weighing 0.047 carats. Gilt hands display the time, complemented by a date function set at the 3 o'clock position. At the heart of this timepiece lies the Longines calibre L592, a self-winding mechanical movement operating at a frequency of 28,800 vibrations per hour. This movement features a monocrystalline silicon balance spring and delivers an approximate power reserve of 45 hours. The watch is completed with a stainless steel bracelet featuring yellow gold detailing, fastened securely with a triple safety folding clasp that includes a push-piece opening mechanism and a fine adjustment system.
