Portofino Hand-Wound Big Date
Portofino Hand-Wound Pure Classic
The Portofino Hand-Wound Day & Date combines the big date at "12 o'clock" with the day display at "3 o'clock".
The displays in clockwise direction from "12 o'clock": the big date, day display, seconds and power reserve display.
Responsible for perfect synchronization between the date discs is the IWC-manufactured 59220 calibre.
The left disc features the figures 0 to 3 and shows the tens while the one on the right has the figures 0 to 9 and shows the ones.
The day display at "3 o'clock" is analogue and has a hand that indicates the day.
Available in stainless steel with a silver-plated dial or in 18-carat red gold with a slate-coloured dial.
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 calibre. The additional day display is directly connected to the date advance mechanism. Two elastic advance fingers, superimposed the one on the other, tap off energy from the barrel throughout the day. By midnight they have built up sufficient power, first to advance the date, and, second to move a seven-toothed starwheel that cause the hand to jump to the next day of the week. Fully wound, the eight-day movement will continue running precisely for 192 hours without the need for any intervention. At that point, the owner will have to supply fresh energy by winding the crown. The power reserve display on the dial indicates when this is necessary. The Portofino Hand-Wound Day & Date is available in stainless steel (Ref. IW516201) with a silver-plated dial, rhodium-plated hands and indices, and a black leather strap from Santoni. The red gold version (IW516203) features a slate-coloured dial, gold-plated hands and 18-carat red gold indices together with a brown leather strap from the House of Santoni.
