The Longines Master Collection L2.449.4.87.6, launched in 2026, embodies a refreshed version of the Master Collection, showcasing a balance between familiar design elements and enhanced case dimensions along with modernized dials, presenting a more contemporary aesthetic. Its round case is made from stainless steel and topped with a scratch-resistant sapphire crystal, treated with anti-reflective coating on both sides to ensure clarity and durability. This watch offers water resistance up to 30 meters.

Accompanied by a stainless steel bracelet, it features a triple safety folding clasp that includes a push-piece release mechanism and a system for fine adjustments. The dial, crafted from white mother-of-pearl, highlights 11 sparkling diamond hour markers, totaling 0.047 carats, from the Top Wesselton VS-SI grade. The blued steel hands sweep over the face to mark hours, minutes, and seconds, while the date appears at the 3 o'clock position. At its heart lies the Longines calibre L592, a self-winding mechanical movement that operates at a frequency of 28,800 vibrations per hour. This precise movement boasts a monocrystalline silicon balance spring and offers approximately 45 hours of power reserve.
