Description

The IWC Schaffhausen Portugieser Hand-Wound Tourbillon Day & Night features an 18-carat Armor Gold® case, renowned for its durability and elegance. The dial is in Obsidian lacquer with gold-plated hands and appliques, creating a striking visual contrast.

At the heart of the watch lies a flying minute tourbillon, one of the most revered complications in horology. Weighing a mere 0.675 grams and comprising 56 intricate parts, this tourbillon rotates within its cage once every minute, minimizing the disruptive effects of gravity on the watch’s precision. The use of silicon and Diamond Shell® technology further enhances accuracy and ensures optimal energy transmission, resulting in an impressive 84-hour power reserve.

One of the most captivating features of the Portugieser Hand-Wound Tourbillon Day & Night is its innovative day and night display. Inspired by a former watchmaker trainee, the display consists of a small globe rotating around its axis, providing a visual representation of the eternal cycle of day and night.

The hand-wound IWC-manufactured 81925 calibre, finished with circular Geneva stripes, is visible through the sapphire glass case back.
