A perpetual calendar in platinum makes its debut in the Portugieser collection. Also making its first appearance is a stainless steel version of the Automatic with a silver-plated dial.

The Portugieser Perpetual Calendar (ref. IW503406) is the first watch in the current Portugieser Collection to have a perpetual calendar and a platinum case. Platinum is inherently a particularly corrosion-resistant and hypoallergenic material. Thanks to its high density, it is extremely robust and durable. The gleaming whitegrey platinum case perfectly matches the silver-plated dial, as well as the rhodium-plated hands and appliques. The case houses the IWC 52615 manufacture calibre. The Pellaton winding is fitted with ceramic components that are practically wear-free, and builds up a power reserve of seven days with its oscillating weight made from solid 18 carat red gold. The highly embellished movement is visible through a see-through sapphire glass back.

The main feature on the dial of this watch is the perpetual calendar. Developed by Kurt Klaus in the 1980s, the mechanism consists of around 80 parts and displays the date, day, month and moon phase, as well as the year in four digits. It can be easily adjusted using the crown. The mechanism identifies different month lengths and leap years automatically and will work until 2100 without needing any correction. This version of the calendar comes with a double moon display that gives an inverted view of the moon phases for both the northern and southern hemispheres. Thanks to a special reduction gear, the display is so accurate that it will only deviate from the actual orbit of the earth’s satellite after 577.5 years, and then only by one day.

In addition, IWC is pleased to present a Portugieser Automatic (ref. IW500712) in a stainless steel case with a silver-plated dial and rhodium-plated hands. This variant most particularly showcases the appliqued Arabic numerals, the railway track chapter ring and the slim feuillehands. The IWC 52010 manufacture calibre has a Pellaton winding with ceramic components. The oscillating weight is fitted with an 18 carat gold medallion and builds up a power reserve of seven days. The watch is worn on a black alligator leather strap.
