IWC unveiled the watch, called DaVinci (a tribute to Leonardo), at the Basel Fair in 1985, with a whopping $25,000 price tag. The watch, if kept wound, would keep track of the day, date, month, year and phase of the moon accurately and without adjustment for the next 214 years. IWC employees took bets on how many DaVincis would sell at the Basel Fair. Many figured 10 to 15, given its price and the weak market for mechanicals. The most optimistic was 30. But IWC took orders for more than 100. The DaVinci convinced Blümlein that the tide was turning, that the classical mechanical watch would not drown in the flood of cheap quartz watches after all. Buoyed by its success, IWC decided to storm the horological Mount Everest. The company assembled a team to go where no watch producer had ever gone before: create a Grand Complication watch for the wrist.
