About the Portofino Hand-Wound Day & Date:
In the Portofino Hand-Wound Day & Date IWC’s designers and watchmakers have combined the big date with the day display and created an aesthetic timepiece that is also enormously practical in use. The date is indicated by the large digits at “12 o’clock”, where we see the perfect interplay of two precisely synchronized discs. One of the two discs bears the numerals 0 to 3 and takes care of the tens, while the second, with figures from 0 to 9 displays the single digits. Responsible for the perfect synchronization between the two discs is the IWC-manufactured 59920 caliber.
