Produced from 1950 until 1985, the reference 2499 is recognized as one of the most important wristwatches made by Patek Philippe. Only 349 pieces were made in total, or an average of only nine pieces per year, with the reference undergoing four major evolutions during its 35-year production run. This piece from the fourth series is a highlight of our Important Watches Part I sale in Geneva on 10 November. #SothebysWatches #PatekPhilippe #SothebysLuxury #WatchesofInstagram
