IWC Schaffhausen Portugieser Chronograph

The IWC Schaffhausen Portugieser Chronograph IW371614 is a chronograph with a 41 mm case in 18 ct 5N gold. The case measures 13 mm thick and carries a rating of 3 bar, or 30 metres. A convex sapphire crystal with antireflective coating on both sides covers the blue dial, and a sapphire window on the back exposes the movement. Small seconds sits on the dial alongside the chronograph counters for minutes and seconds. Inside is the self-winding calibre 69355, which runs at 28,800 vibrations per hour and holds a 46-hour power reserve, with 27 jewels among its 205 components. IWC fits this reference with a blue alligator leather strap, 20 mm at the lugs.
