  • Catalogue Essay

    The IWC Portugieser was first introduced over 80 years ago from the request of two Portuguese businessmen to commission a wristwatch with the precision of a marine chronometer. Since then, the Portugieser has become an important flagship collection of the firm. While the very first examples were chronometer timepieces, the iconic case has housed various complications over the course of its production, including Kurt Klaus’ signature perpetual calendar module.

    The present Portugieser perpetual calender ref. IW503401 was launched with 3 variants in different metals: platinum with silver dial, pink gold with slate dial, and like the present example, white gold with a stunning blue dial. Symmetrically designed with an off-set digital year display, the watch is proportioned in a graceful 44mm diameter case, the radiant blue dial with silver accents gorgeously changes tones under different light. With the hovering double moon display, the moon phases shows the state of the position in both northern and southern hemispheres with a star-studded night sky. Featuring a Pellaton winding system fitted with enhanced wear-free ceramic components introduced in 2015, the IWC-manufactured calibre 52615 movement comprises of 386 components that offers an impressive 7 days of power reserve. Offered in excellent overall condition, the present lot is accompanied by its full set of accessories.
