This is just the sort of publicity a watch manufacture needs - legendary.  What if there was the possibility, that aside from the PERFECT EXECUTION and elegant lines of your new Perpetual Calendar, there was a hidden message engraved on the case.  A message that is not visible to the naked eye and requires a keycode and high tech detective work to solve?  What good is this?  How can the owner appreciate it?  How could this possibly benefit the customer, or the manufacture?

Richard Sheridan, an IWC Collector recently presented a convincing idea that the new IWC DaVinci Perpetual Calendar which demonstrates physical proportions of Phi, the ‘Golden Rule’ (also employed by its renaissance namesake)  uses the case itself, like a computer drive, to store digitally-encrypted information.  Information which is unlocked by centuries-old lore and legend to reveal the ‘Mona Lisa’. 

It really is an intriguing notion that plays on the centuries of questions, and recent popularity of DaVinci in print and cinema.  Furthermore, a notion that is fueled by IWC Schaffhausen’s innovative production of “The Interrogation of Leo and Lisa” starring Kevin Spacey which poses questions on the interpretation of ‘The Mona Lisa’.
