The Longines Flagship Heritage Moonphase (Ref. L4.815.4.62.2) is a distinguished timepiece that seamlessly blends classic design with advanced watchmaking craftsmanship. Housed in a 38.5 mm stainless steel case, this watch features a sunray beige dial adorned with applied indexes and silvered polished hands, all treated with Swiss Super-LumiNova® for enhanced legibility. The dial's subtle domed profile adds to its vintage charm.

At the 6 o'clock position, a sub-dial elegantly displays the moon phase and date, powered by the self-winding mechanical calibre L899.5. This movement operates at 25,200 vibrations per hour and boasts a monocrystalline silicon balance-spring, offering a power reserve of up to 72 hours.

A notable feature of this model is its screw-down case back, which showcases an 18-carat gold medallion depicting a caravel—a sailing ship—set against a vivid blue enamel sea. This emblem pays homage to the original Flagship collection launched in 1957, where each model bore this symbol, signifying Longines' enduring maritime heritage and commitment to timeless elegance.

Completing the watch is a brown alligator leather strap with a traditional buckle, ensuring both comfort and style. With water resistance up to 3 bar (30 metres), the Flagship Heritage Moonphase is a testament to Longines' dedication to blending historical significance with modern watchmaking excellence.
