IWC IW544403 Portugieser Regulateur Platinum Silver Dial LIMITED

The IWC Portugieser Regulateur IW544403 is a distinguished limited edition—just 500 pieces in platinum—presenting a regulator-style display that echoes the precision of historic marine chronometers. Housed in a 43.1 mm platinum case with a sapphire display back, it showcases the hand‑wound IWC Caliber 98245, delivering a refined 46‑hour power reserve. The silver dial features separate sub‑dials for hours at 12 o’clock and small seconds at 6 o’clock, while the prominent central minute hand ensures legibility and horological clarity. Launched in the late 2000s, this model honors IWC’s legacy of pocket‑watch movement innovation, with a three‑quarter nickel‑silver plate, Glucydur screw balance, and elongated precision index. Its platinum case is paired with a black alligator strap, offering both luxury and comfort. Water resistant to 30 m, it balances elegance and technical substance, making it a compelling piece for collectors drawn to regulator complications and IWC’s fine movement craftsmanship.
