Harry Winston Histoire de Tourbillon 10 Watch
Created to celebrate the 10th anniversary of the collection, Harry Winston's Histoire de Tourbillon 10 once again pushes the boundaries of mechanical watchmaking. It's the first watch to pair four tourbillons with four balances, all visible under the synthetic sapphire dial. The tourbillons rotate once every 36 seconds, with a trio of differentials used to average out their slightly different rates and pass them on to the hour and minute hands. Its rectangular case measures 53.30mm wide, 39.10mm tall, and 17.60mm thick, and will be available in ten platinum examples, ten white gold examples, and a one-off model made from the company's proprietary "Winstonium" platinum alloy.
