Portugieser Perpetual Calendar

Technically ambitious and of striking beauty, the Portugieser Perpetual Calendar Ref. IW503302 leaves hardly any wish unfulfilled. The elegant dial not only displays the date, day of the week, month, the four-digit year and the leap year to the year 2100 without any intervention, but also a beautifully staged double moon display for the northern and southern hemispheres, which deviates from the actual moon’s orbit by only one day in 577.5 years. This master achievement is ensured by the automatic caliber 52610, which has a power reserve of seven days. It operates in a 44.2 millimeter and 14.9 millimeter high Portugieser case made of 18k rose gold.
