The IWC Portofino Hand-Wound Tourbillon Retrograde IW516501 is a masterpiece of refined Italian-inspired design combined with haute horlogerie. The 45mm 18K 5N gold case measures 14.1mm thick, with an arched-edge sapphire crystal featuring antireflective coating on both sides and a see-through sapphire glass back.
The silver-plated dial showcases the Calibre 59900 movement with an impressive approximately 192-hour (8-day) power reserve — one of IWC’s longest-running movements. The display features a date, hours, minutes, power reserve indicator, and the mesmerizing tourbillon escapement that continuously rotates to counteract gravitational errors.
Presented on a dark brown alligator leather strap by Santoni, this Portofino Tourbillon Retrograde embodies understated luxury and mechanical excellence. Water resistant to 3 bar.
