The Big Pilot’s Watch Big Date Edition “Zürich” features a stainless steel case, a blue dial and rhodium-plated hands; it is limited to just 50 pieces. Powered by the IWC-manufactured 59235 calibre with manual winding, it boasts a power reserve of 8 days. The date is presented in large numerals by a double date ring with the first disc showing the tens, and the second disc showing the single digits. The power reserve display has moved to the back of the timepiece to retain the characteristically uncluttered dial design of the Pilot’s Watches. The case back features an engraving of a lion, which also adorns the Zurich coat of arms. This Pilot’s Watch is sold exclusively at IWC’s Zurich boutique.
