Vacheron Constantin Malte manual-winding

Vacheron Constantin's Malte manual-winding, reference 81515/000R-9892, comes in an 18K rose gold tonneau case measuring 28.4 mm across and 7.72 mm thick. A sapphire crystal covers the silver dial, and a matching crystal caseback on the reverse shows the movement. The manual-winding calibre 1400 AS carries the Hallmark of Geneva certification and delivers 38 hours of power reserve. Small seconds sit on the dial, and the watch is set with diamonds. It is fitted on an alligator leather strap closed with a pin buckle in rose gold. Water resistance reaches 30 metres, adequate given the dress nature of the piece.
