IWC – PORTOFINO Hand-Wound Tourbillon Retrograde Gold 45

IWC Schaffhausen – PORTOFINO Hand-Wound Tourbillon Rétrograde Gold 45mm

In 2017, for the first time in more than 30 years, the moon phase complication makes a reappearance in the larger Portofino models. At 45 millimetres in diameter and with a classic design, the Portofino Hand-Wound Moon Phase is unmatched for sheer elegance. And with the Portofino Hand-Wound Tourbillon Rétrograde, IWC celebrates a premiere: for this is the first time a model in the Portofino family has featured a tourbillon.

The name of the Portofino Hand-Wound Tourbillon Rétrograde contains three wonderful complications: the hand-wound movement with an 8-day power reserve, the flying tourbillon at “6 o’clock” and the retrograde date display that stretches from “8” to “10 o’clock”. The hand-wound 59900 calibre allows the integration of a hacking tourbillon, which makes it possible to set the time precisely to the second.

The retrograde date display shows the date in analogue form with a date hand that moves in an arc from the 1st to the 31st of the month. The hand jumps back automatically to “one” after the last day of months with 31 days.

In months with fewer than 31 days or when the watch has not been used for a while, the date display can be advanced rapidly and jumps back to the first of the month. The silver-plated dial shimmers brightly inside the 18-carat red gold case.
