Master Collection 30 Stainless Steel / MOP - Diamond / Bracelet

Ref. L2.449.4.87.6

The Longines Master Collection L2.449.4.87.6, introduced in 2026, belongs to an updated generation of the Master Collection. The watches retain the familiar design codes associated with the line while introducing refined case proportions and updated dial executions, giving the collection a sharper and more contemporary appearance. The round case is crafted from stainless steel and fitted with a scratch-resistant sapphire crystal featuring multiple layers of anti-reflective coating on both sides. Water resistance is rated at 30 metres. This reference is paired with a stainless steel bracelet secured by a triple safety folding clasp with push-piece opening mechanism and fine adjustment system. The dial is executed in white mother-of-pearl and set with diamond hour markers. In total, 11 Top Wesselton VS-SI diamonds are used, with a combined weight of 0.047 carats. Blued steel hands indicate the hours, minutes, and seconds, while a date display is positioned at 3 o’clock. Powering the watch is the Longines calibre L592, a self-winding mechanical movement beating at 28,800 vibrations per hour. The movement incorporates a monocrystalline silicon balance spring and provides a power reserve of approximately 45 hours.
