Dressed in a round 42mm stainless steel case measuring 13.6mm thick, the Portofino Chronograph presents a blue dial finished with rose gold-tone leaf-style hands and index hour markers. Roman numerals accent the 12 and 6 o'clock positions, while minute markers trace the outer rim. A day-of-week and date display sits at 3 o'clock, and three sub-dials track elapsed seconds (60), minutes (30), and hours (12) for full chronograph functionality.
Powering the watch is the IWC calibre 75320 automatic movement, based on the Sellita SW500-1, which houses 25 jewels, beats at 28,800 vph, and delivers a power reserve of approximately 44 hours. A scratch-resistant sapphire crystal protects the dial, and the case carries a water resistance rating of 30 meters. The push/pull crown and solid case back complete the specification, with a 20mm black alligator strap secured by a pin buckle.
This example is offered with its original box and papers and carries the Swiss Made designation. Reference IW391036 represents the Portofino collection's characteristic blend of understated elegance and practical timekeeping.
