Vacheron Constantin Traditionnelle moon phase

Vacheron Constantin's Traditionnelle moon phase, reference 7006T/000G-B913, measures 37.5 mm in white gold. The case stands 10.2 mm thick and carries the Hallmark of Geneva, the mark of Genevian craftsmanship and finishing. Inside is the manual-winding calibre 1410 AS, offering 38 hours of power reserve and visible through a display back. A sapphire crystal covers the gold dial, which is set with diamonds and shows a precision moon phase alongside small seconds and a power reserve indicator. The moon phase itself needs correcting only once every 122 years. A dark blue alligator leather strap closes with a white gold pin buckle. Water resistance is modest, rated to 30 metres, in keeping with a dress watch rarely far from a sleeve.
