IWC Schaffhausen's first secular perpetual calendar automatically takes into account the Gregorian calendar's complex leap year exceptions by skipping three leap years over a 400 year period.

This iconic IWC Schaffhausen timepiece has a 44.4mm Platinum case with a see-through sapphire glass case back, allowing the wearer to catch a glimpse of the movement working inside. This watch is powered by the 52640 calibre IWC-manufactured automatic winding movement. It has an impressive 168 hour power reserve, 396 components and 54 jewels. Not only does this Portugieser watch feature small hacking seconds, Pellaton automatic winding, and power reserve display, it showecases an eternal calendar with displays for the date, day, month, year in four digits and the eternal moon phase. It's finished on a striking black alligator strap by Santoni with a width of 22.0 mm.

This watch is inquiry only, and there is no timeline for delivery on this piece.
