In this way, this watch still inherits the classic, elegant appearance of the Royal Oak series, and has the functionality of diving. This watch is equipped with an Audemars Piguet Cal. 3120 automatic movement. To ensure accuracy, the core components of the movement use an adjustable weight balance that vibrates 21,600 times per hour. Eight small weights make the adjustment of the movement more accurate and stable, and can maintain stability for a long time. In addition, it is also resistant to compression, shock and magnetism, and the iconic hexagonal screws on the surface make you feel as if it is solid.
November 22, 2012, Beijing-Internationally renowned watchmaking brand IWC Schaffhausen in Switzerland unveiled its third flagship store in the world and also the largest flagship store in Asia — — Beijing Fangcao flagship store. To celebrate the establishment of a new home in the Chinese capital, IWC has specially created a unique watch tailored for the ancient capital of Beijing-Portugal Sidérale Scafusia Beijing Imperial Palace Limited Edition Watch, which opened the mystery under the attention of the world when the new store opened . The watch is designed according to the latitude, longitude and geographical location of the Forbidden City of Beijing. The star sky map on the back of the watch is a precise astronomical instrument. The mysterious and beautiful sky and starry sky of the Forbidden City have emerged, which is extremely impressive. This watch, which represents the pinnacle of IWC watchmaking technology, will be settled in the new Beijing Fangcao flagship store, and has an exclusive display space to allow customers to appreciate it at close range.
Georges Kern, Chief Executive Officer of IWC Schaffhausen, said: ‘IWC, which has over 140 years of history, has reached a new benchmark with Portuguese Sidérale Scafusia watches. On the occasion of the opening, we presented this unique timepiece especially for watch lovers in China, and showed Schaffhausen’s precision watchmaking tradition and strength with this unparalleled new watch. ‘ The pinnacle of birth
The Portuguese Sidérale Scafusia watch is a masterpiece created by IWC after ten years of in-depth research. It has successfully equipped the watch with solar day, star day and astronomical display. This watch combines a series of surprisingly complex devices with new technical features to highlight the extraordinary skills of the brand. In addition, the Portuguese Sidérale Scafusia watch is the most complicated watch creation in the history of IWC. This watch was created to precisely combine different astronomical displays. When it comes to the attention of this new sophisticated watch, the constant-power tourbillon is not the dial. In addition, the back of the watch is not inferior, neatly displaying the star map, horizon, geographical coordinates, sun day, stellar day, sunrise and sunset display, and day, night and dawn hours in a small space. Even more impressive is that the perpetual calendar is also displayed on the back of the watch with a circular pattern.
Ten years of research and development, the birth of the pinnacle

The time of the earth is based on the length of the average solar day, and the observation of stars depends on the star days of the constellation (in Latin ‘sidus’). The two dates have different lengths. The average solar day is 24 hours in length and measures the average time that the sun passes through a particular meridian. The stellar day is based on an infinitely distant star, which is perpendicular to the observation points at the beginning and end of the observation period, measuring the time required for the earth to rotate around its axis. On the other hand, because the earth not only rotates around its axis, but also rotates around the arc of the sun, the stellar day is about four minutes shorter than the average solar day. The 24-hour display at the ’12 o’clock’ position of the dial is equipped with hour and minute hands, showing extremely accurate stellar hours. The gears developed by IWC engineers are very precise. The annual error of the stellar time is only 11.5 seconds at most, which confirms another technical achievement of Schaffhausen IWC. Extraordinary Tourbillon With the Portuguese Sidérale Scafusia watch, you can time in two different ways side by side. The average solar time, which is how we measure our daily lives, is displayed by the central hour and minute hands. The second hand is displayed on the spherical tourbillon at ‘9 o’clock’. The tourbillon occupies almost a quarter of the entire chassis. Its impressive size is impressive, and connoisseurs appreciate its distinctive design. This watch is equipped with a constant force device, which can offset the power consumption of the barrel’s continuous operation, and can stably transmit power to the balance wheel, which brings the accuracy of the newly designed 94900 manual movement to a higher level. The two barrels are placed in parallel to ensure that the constant force is maintained for at least two days, while the second hand set on the titanium tourbillon frame advances at one second, and during the remaining four days of power reserve time, the tourbillon follows the balance wheel The rhythm continues to run on average, with a vibration frequency of 2.5 Hz, or 18,000 times per hour.

The Portuguese Sidérale Scafusia watch not only has a striking dial, its bottom engraved with the night sky and perpetual calendar is equally attractive. The perpetual calendar is displayed in a circular pattern, counting from the first day (January 1) to the 365th day (December 31); the leap year displays the letters ‘LY’ and the number ‘366’. The perpetual calendar is also connected to the edge of the case back, displaying the current time of the day, the time of the star, and the time of sunrise and sunset, and is accompanied by a 24-hour arrow mark. Finally, the central night sky design with a yellow engraved horizon shows the location of the night sky chosen by the wearer. IWC’s engineers use the coordinates of individual locations to calculate the angle of the horizon, and then mechanically control the cams displayed at sunrise and sunset. The wearer not only owns an extraordinary watch, but also can choose the stars to show the night sky in a specific geographical location. The background of the night sky is further equipped with polarization filters, which are displayed in gray and blue at day and night time, respectively.
Every watch is unique
The Portuguese Sidérale Scafusia watch is accurate, reliable, and exquisitely designed for everyday wear. It is water-resistant to 3 bar, and the compact device is protected against external impacts. In addition, a winder specially designed for the Portuguese Sidérale Scafusia watch can ensure that the watch can operate accurately even after a long period of inactivity. As expected, this IWC Schaffhausen masterpiece is equipped with a magnifying glass, allowing you to view the night sky and comprehensive astronomical data in more detail. Each Portuguese Sidérale Scafusia watch is unique. In addition to the personalized star map on the case back, buyers can also choose a series of case materials and dial designs, as well as the color and materials of the strap. In view of the time required for personalization, and the complicated design and installation of watches, buyers need to wait about one year after purchasing. Of course, exclusive customization is always worth the wait.
Forbidden City Skyline, perfectly presented
To commemorate the historic event of the grand opening of the Beijing Fangcao flagship store, IWC created a Portuguese Sidérale Scafusia limited edition watch tailor-made for Beijing. Watchmakers perfectly engraved the star map above the Forbidden City. The back is clearly presented, and the precision can be called an astronomical instrument. For example, two cities in New York and Beijing are at almost the same latitude. The starry sky above the head may be almost the same according to visual inspection, but the time when each star appears is Different, this is why every Portuguese Sidérale Scafusia watch needs to be tailored according to the customer’s needs. It not only pursues the highest accuracy in time display, but also strives for excellence in astronomical display.
Swiss watchmaker IWC Schaffhausen is dedicated to technology and research and development, and has continuously produced watches of permanent value since 1868. The company eagerly pursues innovative solutions and original technologies, and has won wide acclaim internationally. As one of the world’s leading brands in the field of professional watches, IWC combines precision and unique design to create a model that reflects the highest state of fine watchmaking art.
