This is a big one. We've already shown you a beautiful steel, sector dial Laurent Ferrier for Only Watch 2015, and as of late last night, an incredible unique Tudor designed to mimic one the rarest vintage Tudors of all time (also the first officially unique offering from Tudor or Rolex, ever!) but the Only Watch offering from Patek is something special. The reason being that, in year's past, the charitable auction has, at the end of the day, been something of a one trick pony with more than half of the entire sale's proceeds coming from one watch – the Patek Philippe. Today, we see what mega watch will look like, and the wagering begins.
