IWC Portuguese Perpetual Calendar and Moonphase Watch

It is the wholesale replica IWC watch Portuguese which one might easily have imagined on the wrist of famous seafarers. Learned individuals with the necessary far-sightedness, spirit of discovery and a concrete vision of the future.

This is an ideal combination for a complicated watch with calendar indications displaying the date, day, month, year in four digits and perpetual moon phase. The watch displays advance completely autonomously, mechanically programmed and synchronized with one another. Save for a leap day correction that becomes necessary in February 2100, this continues uninterrupted and without any intervention on the part of the wearer, who simply needs to input the required kinetic energy via the highly efficient Pellaton winding system of the automatic movement when wearing the watch.

The beguiling new eternity in the form of the Portuguese Perpetual Calendar retains its two familiar faces: one model of this watch is equipped with a quasi-universal hemisphere lunar display (Ref. 5021), in which the miniature model of the Earth’s satellite is pictured twice. Exactly as the phases of the moon appear when viewed from the northern or southern hemisphere – that is to say reversed.

A second version of the Portuguese Perpetual Calendar is available with the classic cut-out moon phase display when observed from the northern hemisphere (Ref. 5023). The Earth’s satellite waxes onto this miniature stage from the left behind the semicircular setting becomes visible in the middle as a full moon and wanes on the right side behind the second semicircle. It is accompanied on the moon disc by small raised stars.

The two new models with the representation of the moon behind a setting are now also housed in the 44.2-millimetre case of their sibling models (Ref. 5021). These are the variant in18carat red gold with a silver-plated dial, solid red gold appliqués and a red gold-plated moon surrounded by small stars, and a highly discreet model in18carat white gold with rhodium-plated appliqués and a slate-coloured dial.
As far as the key astronomical indication of the Portuguese Perpetual Calendar, the moon, is concerned, it is able to match the precision of scientific instruments: in these watch models – and in these alone – the gearing has been modified, thanks to the available space, so as to permit the moon cycle to be displayed with unprecedented accuracy.
