    In the Portuguese Tourbillon Hand-Wound, the “whirlwind” – as the word tourbillon translates – revolves on its axis at “9 o’clock” on the dial; or, in nautical terms, at 270 degrees west. The sight of the mechanical, cantilever-mounted minute tourbillon invariably attracts rapt attention from watch lovers. 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 more classical and balanced appearance and optically reduces its height. The dial was chosen to match the case: slate-coloured for the white gold version and silver-plated for the model in 18-carat red gold. The IWC-manufactured 98900-calibre movement with its intricately decorated nickel-silver three-quarter bridge can be admired through the transparent sapphire-glass back. It belongs in the long tradition of the 98 calibre, which was first designed for hunter pocket watches in the 1930s and has since been continuously improved. For this model, IWC’s engineers increased the balance frequency to 28,800 beats per hour, which guarantees excellent precision. The Portuguese Tourbillon Hand-Wound comes with a dark brown Santoni alligator leather strap.
