IWC IW5448-05 description
With its narrow Roman numerals and moon phase display, the Portofino Hand-Wound exudes the same timeless elegance as the original 24 years ago, and has made use of its renaissance to correct a “flaw” – albeit a rather becoming one: the choice of the 98800-calibre hunter movement means that the moon phase and seconds displays are now back at their conventional positions of 12 and 6’clock, respectively.
The movement, which is based on the Jones calibre and features a nickel-plated nickel-silver threequarter plate, screw balance, Breguet spring and elongated index, has also undergone a modification: the accuracy of the moon phase display has been improved to the extent that it deviates by just one day in 122 years from the actual progress of the moon. In addition, the moon phase can easily be corrected using just the crown. The imposing 46-millimetre case remains unchanged.
