The Portugieser Hand-Wound Tourbillon Day & Night IW545901 is a striking example of IWC Schaffhausen's commitment to refined watchmaking and durable craftsmanship. The 42.4mm 18k Armor Gold case frames an Obsidian black lacquered dial that plays with light and shadow, creating a deep, compelling presence on the wrist.

  • Case: Crafted from 18kt Armor Gold known for its enhanced hardness and wear resistance compared to traditional 5N gold alloys
  • Dial: Black Obsidian with gold-plated hands and appliques, polished to a high shine for striking contrast
  • Movement: Manual-winding caliber 81925 featuring a flying minute tourbillon visible at 6 o’clock and an innovative day and night indicator at 9 o’clock
  • Strap: Black Santoni alligator leather, 22mm wide at the lugs, secured by an 18kt Armor Gold folding clasp
  • Power Reserve: Extended 84 hours thanks to the combination of Diamond Shell technology and silicone escapement components

This watch balances technical complexity with an aesthetic that invites prolonged inspection. The skeletonized, gold-plated base plate reveals artisanal finishing details, while practical touches like the tourbillon stop seconds allow for precise time setting.
