Portofino

The white gold version of the Portofino Hand-Wound Monopusher features a slate-coloured dial and a grey alligator leather strap from Santoni. The ingenious single push-button mechanism is integrated in the crown and at first glance barely noticeable. Pressing the multifunctional pusher twice starts, stops and resets the chronograph. The 59360 calibre features an IWC-manufactured chronograph mechanism. With a power reserve of 192 hours when fully wound, it guarantees the wearer 8 days of constant accuracy. The power remaining can be read off on the power reserve display on the dial between “8” and “9 o’clock”. The subdial at “12 o’clock” displays the minutes clocked by the stopwatch while the central hand shows elapsed seconds. In combination with the small seconds display at “6 o’clock” and the date display at “3 o’clock”, this gives the dial a pleasingly balanced appearance.
