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. A new feature this year is the arched-edge front glass, which gives the watch a more classical and balanced appearance and optically reduces its height.The ref. IW5463-04 Portugieser Tourbillon Hand-Wound “Metropolitan Boutique Edition” is a limited edition of 50 pieces with red gold case and olive dial created for a select number of IWC boutiques.
