Portugieser Yacht Club Chronograph Steel (IW390503)
The IWC Portugieser Yacht Club Chronograph (ref. IW390503) features the IWC-manufactured Caliber 89361 mechanical automatic movement with an approximate 68-hour power reserve when fully wound; slate gray dial; flyback chronograph function with hour and minute counters combined in a totaliser at 12 o'clock; date aperture at 3 o'clock; small seconds subdial at 6 o'clock; sapphire-crystal, transparent case back; and 43.5mm, stainless steel case on a black rubber strap with a stainless steel deployant clasp.
The Sportiest Member of the Iconic Portugieser Family
Powered by the in-house 89361-caliber movement and water-resistant to 6 bar, the chronograph demonstrates its sporting qualities with a flyback function and an additional flange with quarter-second calibration for short stop times. Stop times longer than a minute are shown like the time of day on a separate analogue subdial. In response to the requests of many watch aficionados, the case diameter on the new IWC Yacht Club Chronograph has been reduced from 45.4 millimetres to 43.5 millimetres relative to its predecessor.
