There seems to be a link between the Roths and the company which built the watch.
The name of the company is IWC Schaffhausen.
This article in German states that David Roth's Malthusian propaganda expeditions are partly funded by IWC.
"Zwischen März und Ende Juli 2010 segelte er 8000 Seemeilen von Kalifornien nach Sydney, als «Unterstützer» war auch die Schaffhauser Uhrenfirma IWC an Bord."
