Master Collection 30 Stainless Steel / Frosted Blue - Diamond / Bracelet

Ref. L2.449.4.97.6

The Longines Master Collection L2.449.4.97.6, introduced in 2026, forms part of a refreshed generation of the Master Collection. The watches retain the familiar design language associated with the line while incorporating refined case proportions and updated dial executions, resulting in a sharper and more contemporary appearance. The round case is crafted from stainless steel and fitted with a scratch-resistant sapphire crystal with 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 finished in frosted blue with a sunray effect and set with diamond hour markers. In total, 11 Top Wesselton VS-SI diamonds are used, with a combined weight of 0.047 carats. Silvered polished 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.
