IWC IW390507 Portugieser Yacht Club Flyback SS Blue Dial

The IWC Portugieser Yacht Club Flyback reference IW390507, introduced in 2018 as part of IWC’s Summer Editions, is a compelling blend of nautical sportiness and horological refinement. Housed in a robust 43.5 mm stainless steel case with integrated crown guard and sapphire crystal caseback, it delivers a 60 meter (6 bar) water resistance—ideal for maritime pursuits. Powered by the in‑house automatic Caliber 89361 with flyback chronograph and 68‑hour power reserve, the movement displays elapsed hours and minutes on a single subdial at 12 o’clock and benefits from a quarter‑second scale for precision timing. The vibrant blue dial, accented by white chronograph counters and a red central seconds hand, evokes the spirit of the open sea, while luminescent hands and markers ensure legibility. This model’s sporty rubber strap in matching blue reinforces its summer‑ready character. As a limited Summer Edition, it stands out in the Portugieser lineup for its seasonal exclusivity and collector appeal. The IW390507 is a refined expression of IWC’s maritime heritage, offering technical sophistication, manufacture movement, and a distinctive aesthetic for discerning enthusiasts.
