This November, Sotheby’s will offer a unique example of the Patek Philippe 1518 Reference which broke new horological ground when it was first introduced in 1941. The current example is not only extraordinary in its design elements but also in its exceptional provenance, having been commissioned by Hans Clarin Hovind Mustad (1871-1948), one of the fathers of modern car engineering, to Patek Philippe in spring 1944 and delivered to him in November that same year. This Patek Philippe 1518 reference – estimated to achieve in excess of 2 Million CHF ($2 Million) – is one of the star highlights of Sotheby’s Important Watches: Part I auction taking place in Geneva on 5 November.
