    Portuguese Perpetual Calendar Iw502305 Introduction

    The IWC watch factory has carefully modified the appearance of the Portuguese Perpetual Calendar watch, and further extended the lineup of this long-time calendar chronograph expert: adding two new models of red gold and two new models of platinum, making the series more rich . Technically, this model has reached the top of the ridge, reaching perfection. This timepiece with a perpetual calendar shows the ultimate perfection.
     If a navigator Fernando Magellan wears a watch, it is easy to associate it with a Portuguese watch. It is an inevitable choice for wise men with a spirit of exploration, forethought, and insights into the future. Because the realm of this timepiece’s specialty is insight into the future, and in addition to its technically stunning, the way the time is displayed is equally interesting. The perpetual calendar of the watch is exactly as it was when it was born 25 years ago. It is sophisticated, intricate and precise, and complements the IWC-manufactured large-scale 5000 movement with a 7-day power reserve display.
     Its calendar functions include date, day of the week, month, four-digit year and perpetual calendar moon phase display, the most ideal combination of functions for complex watches. The display function of this watch is fully autonomous, and the various displays are synchronized by means of a mechanical setting operation procedure. The only exception is the need for the next day’s correction in February 2001. This operation does not interrupt the operation of the watch and does not need to be mediated by the wearer. They only need to wear the watch as usual, and they can provide the required kinetic energy through the high-efficiency Bilerton detent winding system equipped with an automatic movement. The complex Gregorian calendar always strives to keep the length of each year constant, and according to its calendar, there will be no next day at the end of February 2100, which needs to be adjusted by watchmakers. Therefore, it is best to remember to remind the owner’s grandchildren or even great-grandchildren of this situation. In addition, in the distant 2100, the century display slide at the end of the narrow conveyor belt will advance a few millimeters. The number ’20’ currently displayed in the display window will be replaced by ’21’ to completely display the future One hundred years.

    The pleasing new timeless work & mdash; & mdash; The Portuguese perpetual calendar watch uses the classic silhouette moon phase display, showing the changes in the moon phase observed from the northern hemisphere (model: 5023). This earth’s satellite enters this miniature sky stage from below the left semicircle, gradually becoming round and full, reaching a full moon when it reaches the middle position, and then showing the moon loss process under the cover of the second semicircle on the right. The moon phase disc is even more dotted with stars around the moon, forming a realistic night sky scene. A new watch with a classic moon phase display, with a 44.2 mm case. They each use a silver-plated dial and a dark blue background to set off a red-gold-plated moon pattern.
    As far as the moon phase astronomical display function of the Portuguese Perpetual Calendar is concerned, its accuracy is comparable to that of scientific instruments: only in these models with large cases, the moon phase gear has ample internal space improved , So that the display of the moon phase cycle to achieve unprecedented accuracy. Each lunar revolution cycle (29 days, 12 hours, 44 minutes, and 3 seconds) will only produce a trivial 12-second residual error, which will accumulate one day of error every 577.5 years. In other words, according to the current level of human knowledge, only the moon in the sky can be more accurate than it. And the gap is even smaller.
