Vacheron Constantin Traditionnelle moon phase

Vacheron Constantin's Traditionnelle moon phase, reference 83570/000R-9915, is a 36 mm rose gold watch set with diamonds. The case measures 9.1 mm thick and pairs with a manual-winding calibre 1410 AS, carrying 38 hours of power reserve and bearing the Hallmark of Geneva. A sapphire crystal covers the white dial, and a transparent sapphire caseback shows the movement's finishing. The moon phase sits at the centre of the dial with a starry-sky motif, small seconds and a power reserve display complete the layout. An alligator leather strap closes with a rose gold pin buckle. It stays water resistant to a depth of 30 metres.
