David was among nearly 3,000 others who showed up for an "Antiques Roadshow" tour stop in West Fargo with items to be appraised in hopes of striking it rich.
The Rolex watch David had with him was as new as the day he bought it more than 40 years ago. Never once did he put it on his wrist.
The military veteran soon left the Bonanzaville history museum complex under security escort and with a truly staggering estimate of what the Swiss-made watch could bring at auction: Up to $700,000.
Now that rare Rolex, a model made famous a half-century ago by Hollywood legend Paul Newman, is making an internet star out of the man whose identity remains a closely guarded secret.
David's appearance on "Antiques Roadshow" aired Monday, revealing to the world the potential six-figure value of the Rolex Cosmograph he bought for $345.97 in 1974 while serving in the Air Force clearing roadside bombs in Thailand.
Hearing that number sent David — shoulder-length gray hair and long, bushy beard and all — collapsing to the ground as the TV cameras rolled to document the highest-value appraisal made during the public television series' 24th season.
"You OK?" said appraiser Peter Planes, who walked around the high-top table where the watch was displayed and checked on his floored guest.
"Unbelievable," said a smiling and back-on-his-feet David, who also let out a censored expletive for the first time during Planes' breakdown of the watch's special attributes.
