In 2015, the Year of the Portugieser (Portuguese), IWC’s newly developed annual calendar is another attractive complication. Located at “12 o’clock” on the dial, the annual calendar shows the month, date and day in three separate, semicircular windows. The switching mechanism automatically takes into account the differing lengths of individual months. Unlike a perpetual calendar, however, the annual calendar is unable to factor in the differing length of the month of February or the leap years. Once a year, then, at the end of February, it requires manual correction. The necessary correction is made as simply and conveniently as possible via the crown. In order to free up as much space as possible for the date display, the designers replaced the indices from “11 o’clock” to “1 o’clock” with the three display discs. The rare combination of an annual calendar and 7-day calibre should make this latest complication from the House of IWC even more fascinating for watch connoisseurs. The timepiece is available in an 18-carat red gold case with a silver-plated dial or in stainless steel with a silver-plated or midnight blue dial. The arched-edge sapphire glass makes the case look slimmer and underscores the watch’s classic elegance. The curved strap horns ensure greater comfort even on a slimmer wrist. On the reverse side, the see-through sapphire-glass back provides an unimpeded view of the exquisite new IWC-manufactured 52850 calibre.
