Portugieser Perpetual Calendar Tourbillon Edition "150 Years"

IWC 2018

ref. IW504501
Men's

As part of its 150th anniversary celebrations this year, IWC has added five new models to the Portugieser range, including a Perpetual Calendar with flying Tourbillon. This is the first time the Schaffhausen firm has combined these two complications. The calendar displays the date, day, month, four-digit year and moon phases. So that the flying tourbillon, made from 82 components and weighing a scant 0.635 grams, can be visible at 12 o’clock, an opening has been made in the calendar advance ring while moon phases have been incorporated into the month subdial at 6 o'clock. Limited edition of 50 pieces.
