MASTERPIECES OF HAUTE HORLOGERIE

IN THIS LATEST COLLECTION, TWO MODELS DEMONSTRATE IWC’S EXPERTISE IN THE PREMIER LEAGUE OF THE ART OF WATCHMAKING

The tourbillon is one of the most fascinating achievements in the art of watchmaking. The balance in its cage rotates around its own axis once every minute, creating an optical spectacle on the dial. But that is not all: the continuous rotation also reduces the influence of gravity on the oscillating system and thus improves the watch’s precision. We are proud to present these complications in our new timepieces that carry the Calibres 89000 and 51000.

Calibre Family 89000

For the first time ever in the Portugieser family, the Portugieser Tourbillon Rétrograde Chronograph with the IWC-manufactured 89900 calibre brings together a flying tourbillon at “6 o’clock” with a retrograde date display and a chronograph with flyback function. The pallet and escape wheel have a special coating. The latter reduces friction and improves the energy flow in the movement. One model is offered in 18-carat Armor Gold®, a specially hardened version of 5N gold. A second model comes in platinum.

In the two complications that give the watch its name, the Portugieser Perpetual Calendar Tourbillon combines two of watchmaking’s greatest challenges on the dial. The tourbillon comprises 82 individual components and weighs just 0.635 grams. The perpetual calendar’s moon phase display is so precise that it will need to be adjusted by one day only after 577.5 years. The IWC-manufactured 51950 calibre’s self-winding system builds up a power reserve of 7 days. This watch will likewise be available in two limited models in 18-carat Armor Gold® and platinum.
