The technical refinements of the
Portuguese Grande Complication
Your IWC watch shows you the time in hours, minutes and seconds, as well
as the moon phase, the date, the day, the month and the year in four digits.
You can use the integrated chronograph to measure any period of time in
seconds, minutes and hours. Stop times can be added together. The strike
train of the Portuguese Grande Complication chimes the time – in hours,
quarters and minutes. The Portuguese Grande Complication from IWC is a
mechanical masterpiece. The mechanical movement with automatic wind-
ing has 75 jewels (synthetic rubies) and a power reserve of approximately
44 hours when fully wound. Your Portuguese Grande Complication is pro-
tected by an arched-edge sapphire glass of hardness grade 9 on Mohs'
scale. Your watch is water-resistant 3 bar. In addition to the uniqueness of
its functions, it is the display's legibility and the ease with which it can be
used that distinguishes this watch from all other complicated timepieces. To
ensure that this extraordinary watch continues to perform faultlessly in the
future, it is essential to observe a few important operating instructions.
