As the fifty-year anniversary of the untimely assassination of President John F. Kennedy rolls around this week, politicos, historians, and collectors alike will have the chance to bid on a piece of that fateful November 22. The wristwatch used to declare JFK dead at Parkland Hospital in Dallas will be sold at auction on December 17.

According to Christie’s, the timepiece owned and used by Dr. Kemp Clark to declare the president dead at 1:00 p.m. on November 22, 1963 is expected to fetch between $100,000 and $150,000.

The item itself is 18-carat gold and was manufactured by Patek Philippe, the prestigious Swiss watchmaker. And this particular series was the company’s first water resistant chronograph wristwatch.

It was bought in 1949 by Dr. Clark’s mother for 1290 Swiss Francs, the equivalent of $1,416 U.S. dollars then, roughly $10,000 when accounting for inflation. The watch has his name engraved on the back.

Dr. Clark wore the watch throughout much of his career, during which he created the likes of the neurosurgery service at Southwestern Medical School and Parkland Hospital in 1956 and the neurosurgery residency program in 1962, among his many other notable achievements.

According to the Associated Press, “A portion of the proceeds from the auction will be donated to the Red Cross.”

Dr. Clark died in 2007.
