John F. Kennedy’s nephew Anthony Shriver, the son of John F. Kennedy’s sister, Eunice, and her husband, Sargent Shriver, had family on his mind at an intimate party celebrating the partnership between his nonprofit, Best Buddies, and Hublot watches on Sept. 6 in Woodside, California.

The event was celebrating a new, limited edition Hublot watch that highlights the continuing partnership between the two organizations. A percentage of each watch sold will benefit Best Buddies programs in the U.S. and globally.

Shriver, 53, who founded the nonprofit program Best Buddies, which advocates for individuals with intellectual and developmental disabilities, shared fond memories of his cousin, Christopher Lawford, who died from a heart attack at age 63 on Tuesday, as well as his aunt, Rosemary Kennedy, whose disability spurred the foundation of Best Buddies.
