Before a mechanical watch movement can start moving, it needs an energy source to drive it. That energy source is the mainspring. And while there are some who enjoy engaging with the machine, lovingly winding it by hand, others take pleasure in the automatic mechanism, which will keep the watch running indefinitely, simply from the movements of the wearer's arm.

IWC Oils
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.

Grande Complication Dial Explained
Small World

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.

89800 Calibre Movement
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.

Experience - 51011 Calibre - Hero

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.
