The “Histoire de Tourbillon” saga by Harry Winston is coming to an end. This series of watches was the home for some of the most extravagant pieces created by the brand, together with the Opus series. Having previously used tourbillons with single, double or triple axes, combined (or not) with single or double tourbillons or a carousel, Harry Winston’s latest creation is the last page of a book that impressed over the years. But like all good stories, the end is mindblowing. Meet the Harry Winston Histoire de Tourbillon 10, the first watch ever equipped with four tourbillons in a single movement.
