Time That Runs Like Clockwork

Depending on the stresses and strains to which they are exposed, around 50 points in the movement are treated with oils and greases developed especially for use in wristwatches.

Test Lab

At IWC Schaffhausen, new watch models are put through a gruelling test program involving up to 50 separate stages that include long-term immersion in warm salt water and being locked away in an environmental chamber. All this guarantees that they will be equipped for everyday use – and much more – when they finally reach their future owners.

For the MERCEDES AMG PETRONAS Formula One™ Team, following the Grand Prix circus means transporting 30 tons of material in 10,000 individual parts and at least 60 employees to venues on five continents. Of course, they have to ensure that everything arrives there on time what calls for a system and improvisation in equal measure.

Eternity in Digits

The IWC-manufactured 89800 caliber, which made its debut in 2009, redefined the digital date display. The triple-disc mechanism in the perpetual calendar features large-format displays for the date and month and, slightly more discreetly, the leap year cycle. All are ingeniously synchronized.

Top Secret

In a small town in central England, over 500 specialists spend their time developing and building silver arrows for the MERCEDES AMG PETRONAS Formula One™ Team. Almost every one of the 3,200 parts in each car is custom-made.

Ingenieur: the story of a legend

When the Ingenieur from Schaffhausen was launched in 1955 it created a storm. But its actual history goes back much further: to 1888.

Movements Come to Life

All mechanical watches can be fascinating because of their intricate movements. Even simple watches, ones that only tell time, are extraordinarily complex mechanisms that have hundreds of miniscule parts that work harmoniously together. A complicated watch, one that performs additional functions, is by definition even more complicated.

Time moves the world. The IWC Portuguese Grande Complication is an understated, beautifully designed way of summarizing time as the motor of all change: a time machine that shows a tilted globe on the dial. The depiction also references the historic background of the Portuguese, a nation of fearless seafarers who gave their name to the watch family.

The Arabic numeral appliqués and the railway-track-style chapter ring are signature elements of the Portuguese watch family. The dial features elegant, feuille-style hands that show the hours and minutes, together with a slim chronograph hand that shows stop times in seconds.

In this tiny window, two discs and a century slide show the correct year in four digits without any help from the user until 2299 – even until 2499 after exchanging the century slide. The day of the week and the seconds are displayed in a subdial at 9 o’clock.

Small, but no less important: the blued hand at 3 o’clock shows the date correctly even in months with fewer than 31 days and in leap years – until the year 2100. The months and stop times in hours recorded by the chronograph are shown in a combined totalizer at 6 o’clock.

When it comes to the moon, the Grande Complication is no less accurate: the display deviates from the actual progress of the moon by just one day in over 500 years. The disc completes one rotation in two full lunar periods. The same display shows stop times up to 30 minutes.

Portuguese Grande Complication, Ref. 3774, in a platinum or red-gold case, limited to 100 watches per year. Self-winding, perpetual calendar showing the date, day, month, and the four-digit year. Perpetual moon phase display. Stopwatch function with aggregate timing up to 12 hours. Minute repeater for the time in hours, quarters and minutes. It only takes a 45 mm diameter and a 16.5 mm height to house such a complicated world.
