IWC Portugieser Chronograph

This IWC Portugieser Chronograph reference IW371445 is presented in excellent condition and comes complete with its full set of box and papers. A design icon within the IWC collection, this model combines timeless elegance with precise Swiss engineering.

The 40.9 mm stainless-steel case is beautifully proportioned, featuring polished sides and brushed lugs that highlight its classic silhouette. The slim bezel maximises the dial’s visual presence, while the sapphire crystal ensures clarity and protection from scratches.

The silver-plated dial is the centrepiece of this reference, accented by blue feuille-style hands and matching applied Arabic numerals. Twin sub-dials display running seconds at 6 o’clock and a 30-minute counter at 12 o’clock, maintaining the Portugieser’s signature symmetrical balance. A fine minute track along the perimeter pays tribute to IWC’s original marine chronometers.

Inside beats the IWC calibre 79350, a self-winding chronograph movement based on a heavily refined ETA 7750 architecture. It delivers smooth chronograph operation, crisp pusher response, and a 44-hour power reserve, combining reliability with precise performance.

This example is fitted with an alligator leather strap, offering both comfort and understated luxury. It is secured by a polished stainless-steel pin buckle engraved with the IWC logo.

The IWC Portugieser Chronograph IW371445 is one of the most recognisable and enduring designs in modern watchmaking — a harmonious balance of precision and elegance. This full-set example, in excellent condition, perfectly represents IWC’s heritage of craftsmanship and timeless style.
