The Portugieser Tourbillon Hand-Wound Story

In the Portugieser Tourbillon Hand-Wound, the “whirlwind” – as the word tourbillon translates – turns at “9 o’clock” on the dial. The tourbillon rotates around its own axis once every 60 seconds to counteract the pull of gravity on any disequilibrium in the balance wheel that would adversely affect the watch’s rate and accuracy. The arched-edge front glass gives the watch a classic, balanced appearance. The horns have also been ergonomically optimized to make the watch more comfortable to wear on a slimmer wrist. The IWC-manufactured 98900-calibre movement with its intricately decorated nickel-silver three-quarter bridge can be admired through the transparent sapphire-glass back. The 18-carat red gold version comes with a dark brown alligator leather strap from the House of Santoni.

Calibre Family 98000

The 98000-calibre family, with design cues taken from the first F. A. Jones movements – for example the “F. A. Jones arrow”, which facilitates quick, easy adjustment of the spring length – is ideally suited for use in large hand-wound Portugieser models.

Tourbillon

The tourbillon, French for “whirlwind”, is considered to be one of the most exclusive complications in the world of haute horlogerie. The complex mechanism is assembled from start to finish by an experienced master watchmaker.
