Vacheron Constantin Traditionnelle tourbillon chronograph

Vacheron Constantin's Traditionnelle tourbillon chronograph, reference 5100T/000R-B623, measures 42.5 mm in rose gold. The case stands 11.7 mm thick and pairs with a white opaline dial. Inside is the manual-winding calibre 3200, bearing the Hallmark of Geneva, with a power reserve of 65 hours shown at 6 o'clock. A sapphire crystal covers the dial, and a matching sapphire caseback lets the tourbillon and finishing show through. This is a chronograph with a 45-minute counter, and the tourbillon carriage at 12 o'clock also carries the small seconds. The alligator leather strap closes with a folding clasp in rose gold. Water resistance is set at 30 metres.
