IWC PORTOFINO MIDSIZE AUTOMATIC DAY & NIGHT

The new Portofino Midsize Automatic Day & Night with a 24-hour day/night display and a second time zone combines discreet luxury with the suave urbanity of a modern, mobile generation. It is not only the diamonds and mother-of-pearl that shine on this watch; the beautiful and practical complication is also a wonder to behold. It is the perfect timepiece for people who do business or travel worldwide,for jet-setters and for night owls.

A SECOND TIME ZONE – AS BEAUTIFUL AS I T IS PRACTICAL

A second time zone is a beautiful and practical complicationthat is enjoying increasing popularity around the globe. While the hour, minute and seconds hands display local time, the blue hand on the inner 24hour ring shows the time at a second location of the wearer’s choice. It could just as easily be the time back home or in a city on the other side of the globe where a business partner resides – after all, the last thing you want to do is call at an inconvenient time. To make reading the time in the second location easier, the lower half of the ring, from “6 a.m.” to “6 p.m.”, is white, while the top half, from “6 p.m.” to “6 a.m.”, is blue, allowing the wearer to easily differentiate between day and night. This dark blue, which is also used for the fourth hand, is wonderfully accentuated against the shimmering white motherofpearl dial. The crown provides a fast, simple means of setting the time separately on the dial and in the inner 24hour ring. Pulling the crown out to a specific position allows the user to set the hour and minute hands after arriving in a new time zone. The small blue hand remains in position and continues to show the time back home. When required, the crown can be pulled out to a second position that allows the hand to be adjusted backwards and forwards in onehour steps.

THE LONG TRADITION OF THE 24-HOUR DISPLAY

The new Portofino Midsize Automatic Day & Night unites three watchmaking inventions from over a century of IWC history on a single dial. When the 24hour day was introduced in the late Middle Ages, people were a little perturbed by the fact that every point on the 12hour dial showed a time that could be either day or night. In the absence of daylight or other natural indicators, it is, for instance, hard to determine whether it is 10 o’clock in the morning or in the evening, a.m. or p.m. The 12hour dial prevailed due to practical considerations. One of the reasons was that a small watch is easier to manufacture and has a longer service life. For the ambitious watchmakers of modernity, it meant a greater incentive to find elegant solutions for a large watch. Dividing the day into 24 hours enjoyed a surge of popularity towards the end of the 19th century after the world was separated into 24 time zones at the 1884 International Meridian Conference in Washington. IWC Schaffhausen latched onto this trend and in 1887 produced a pocket watch with a convertible case and 24hour display: the “Magique”. Although more pocket watches with oversize displays appeared in subsequent years – destined mainly for the Italian market – they remained watchmaking rarities. A century after the Magique,IWC introduced a watch with a 24hour ring in colours that clearly divided it into day and night. In 1998, IWC’s designersspawned the Pilot’s Watch UTC (Universal Time Coordinated) with a separate, second time zone. By then, all the watchmaking features that were needed to provide the face of the new Portofino Midsize Automatic Day & Night already existed.
