Presented as nothing less than “Rolex’s magnum opus” (the most important watch ever produced by Rolex), John Goldberger’s “Unicorn” was the star of Phillips’ “Daytona Ultimatum” auction. The rarity, believed to be the only manual-winding Daytona ever made in white gold, was expected to make in excess of 3 million Swiss Francs. In March 2018, when Vacheron Constantin flew me in to visit their manufacture in Geneva, I took the opportunity and dropped-by the Phillips headquarters to see the “Unicorn” and others in the flesh.
