NEW YORK (AP) –  A wristwatch that is believed to have been used to declare 
the time of President John F. Kennedy’s death is going on the auction block in 
New York City.

The 18-carat Patek Philippe timepiece is estimated to bring up to $150,000
at Christie’s on Dec. 17. The stopwatch (above) was made in 1948 and was 
purchased for Dr. Kemp Clark by his mother in Switzerland a year later for
$750.

Clark was one of several attending physicians at Parkland Memorial Hospital
in Dallas on Nov. 22, 1963, when president Kennedy entered the ER. He was
pronounced dead at 1 p.m. by referring to the watch, according to his family,
and signed the death certificate.

"There is endless debate among historians on the actual time of death and
there was most likely also a clock in the ER," said John Reardon, Christie’s
international co-head of watches. "However, the family and historians agree
to these facts: the watch was on his wrist that day and he called the time of
death and signed the death certificate."

A portion of the proceeds from the auction will be donated to the Red Cross.
