On December 17th, Christie’s will be auctioning off Patek Philippe reference 1463 in 18-carat gold. The Reference 1463 was Patek Philippe’s first water-resistant chronograph wristwatch. This Patek Philippe is no ordinary Patek Philippe, it was worn by Dr. Kemp Clark. Dr. Clark was one of the doctors at Parkland Memorial Hospital in Dallas on November 22,1963, the day President John F. Kennedy was assassinated. This wristwatch is believed to have been used to declare the time of President John F. Kennedy’s death.

Dr. Kemp Clark received this Patek Philippe in 1949 by his mother. The watch was purchased at that time for $750 in Switzerland. Today, the watch is projected to bring $150,000 at the upcoming auction this December.
