StarTribune: Guest in North Dakota on 'Antiques Roadshow' told watch worth up to $700K

David said during the episode that “I knew that the Rolex watch was good for scuba diving” and a favorite among commercial airline pilots, so he spent what for him at the time was about a month’s military salary on the timepiece and stashed it a safe-deposit box.

“I never used it,” he said. “I looked at it and I said, ‘You know, this is really too nice to take down in the salty water.’ ... I only took it out like two or three times to look at it, and that was about the extent of it before I brought it here."
