For its seventh edition, the Christie’s-hosted Only Watch charity auction has procured 50 lots of exceptional merit from some of the most important names in watchmaking. All profits from sales, which commence online and in Geneva on Nov. 11, go to Duchenne Muscular Dystrophy research. The auction and 10-city watch tour, currently underway, both receive patronage from H.S.H. Prince Albert II of Monaco, and the globe-traveling event commenced at the Monaco Yacht Club. Estimates for the wristwatches range from $4,600 to more than $1,000,000, with value derived from the timepieces’ sheer rarity and to unique, exciting experiences that are being packaged with some of them. Whether it’s the introduction of a vibrant new material, technical complications, or uncommon variations (such as a left-handed model), these 18 selections are ones for collectors to watch.
