Few complications in Haute Horlogerie fascinate as much as the tourbillon. Thanks to this system, the balance wheel rotates around its axis inside a cage. In addition to offering a striking spectacle on the dial side, this constant rotation reduces the influence of gravity on the oscillation system and improves the precision of the watch. The Portugieser Tourbillon Rétrograde Chronograph has a flying minute tourbillon at 6 o'clock. It is also equipped with a retrograde date display and a chronograph with flyback function. Produced in a limited edition of 50 pieces, this model has a platinum case. The silver dial and the rhodium-plated hands and appliques perfectly complement this rare and precious metal. The self-winding IWC-manufactured calibre 89900 ensures a power reserve of 68 hours. The pallet and escapement wheel benefit from Diamond Shell® technology, which reduces friction and smooths the transfer of energy inside the movement.
