Like many F1 drivers Schumacher got his
link start in karting but that's not what the "CART" logo on the six o'clock sundial is referencing. It's the Championship Auto Racing Teams' logo a race series that ran from 1979-2003. The dial is the showstopper here in a brilliant shade of blue. The reference also comes without the CART logo at six o'clock
link but
link I think it adds a lot of character to the watch.
