Thanks SJX and Rolf for the interview.
The Sonata is also special to Rolf because the funky see-through hands were at his suggestion. At the beginning, they seemed a bit freaky but eventually, people got used to the better visibility.
I remember the first platinum UN GMT +/- Perpetual with Sonata hands came out in 2004 and there was a mini-fight between a couple of PuristS......eventually a fine southern gentleman from USA won it
Regards,
MTF
