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.

From Atomic Physics
to Quality Management

A doctor with a degree in atomic and molecular physics plays a surprising and important role at IWC.

Flying high with big date and month displays

A fabulous combination of sportiness and elegance, the Spitfire Perpetual Calendar Digital Date-Month is the high-flyer of the IWC Pilot's Watch collection. The date and month could not be easier to read and the mechanics inside the case are an endless source of fascination.

Experience - 51011 Calibre - Hero
—In 2000, after five years of development, IWC unveiled the Portuguese Automatic with the 5000 calibre, a movement that had been designed and produced in its own workshops
Portuguese Automatic

—The IWC manufactured 51011 calibre integrates the finest features ever to grace an automatic movement

It’s no accident that this calibre has a gold medal

—Kurt Klaus, the legendary watchmaker who further improved this movement

Also rightly called the big IWC calibre. Manufactured in-house at the factory in Schaffhausen, it resulted from the first movement in the 5000-calibre family for a limited series of Portuguese watches in 2000. It also marked the revival of the Pellaton pawl-winding system at IWC. The version of the 51011 illustrated here, featuring circular graining, nickel plating and Geneva stripes decoration, is the driving force behind the Portuguese Automatic with small seconds, date and power reserve display.
