Portugieser Tourbillon Hand-Wound
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.
