AUDEMARS PIGUET Audemars Piguet is one of the brands that have already developed ceramic case. We have seen many ceramic case works in the Royal Oak offshore series in the past, but with the recent years The ceramic ring has gained a lot of popularity, and the all-ceramic shell with a more comprehensive range and a higher fragility risk is not as compact as it was a few years ago. This is evident from the fact that Audemars Piguet has launched fewer ceramic shell works in recent years; however, the brand is not comprehensive The production of ceramic shells is discontinued. For example, in 2019 they launched the new Royal Oak Perpetual Calendar white ceramic shell. This perpetual calendar model has been continuously updated for several years since its introduction in 2015, except for the rose gold and stainless steel versions, A more expensive platinum model is also introduced, or in 2017, the all-black ceramic shell style was also introduced first. This time, Audemars Piguet added a white ceramic shell to make the series more selective.
The inner ring of the case is provided with a 52-week scale display, which is more special in the perpetual calendar watch. The concise black Arabic numerals and slender arrow-shaped hands jointly display the week number of each year.
Feature 1: The case is slightly enlarged, and the week number display of the dial is a major feature
When the Royal Oak Perpetual Calendar was remodeled and re-released at the time, the table diameter was increased from 39mm to 41mm. For complex watches with hours, minutes, seconds, perpetual calendar indication and moon phase profit and loss display, increasing the table diameter The layout of the faceplate can be made more relaxed, and the larger case can also show the atmosphere of a high-end watch. The dial of this watch is no exception and it still uses the ‘Grande Tapisserie’ plaid to enhance the overall beauty and recognition. In addition, the watch’s outer ring displays 52 weeks of the year, and with the central hand, the time display is more hierarchical. It is a little different from AP’s previous perpetual calendar display, because it uses the third central pointer to match the scale on the outer circle of the dial to indicate the week number.
According to AP’s official data, this chain is full ceramic and has no additional metal lining. This will not only make processing more difficult, but also require higher wearing safety (falling off due to chipping).
Feature two: Ceramic chain belt is not easy to make
A unique feature of this ceramic perpetual calendar is that the bracelet is made of ceramic. In the past, the straps used by APs in the offshore or conceptual models were almost always tape. The ceramic bracelet has been used since After the black ceramic version was applied, it slowly began to sprout in the Royal Oak series, and the powerful impression of the Royal Oak’s full circle of metal covering the wrist was originally one of the attractive features of RO. If it was replaced with tape or belt, this This kind of impression will be weakened relatively, so if the ceramic case is matched with a ceramic chain like a metal chain, the rough feeling of the sports watch will also rise.
Caliber 5134 is based on Audemars Piguet calibre 2120, the world’s thinnest perpetual calendar movement created in 1967. The exquisite hollowed-out automatic dial is even more engraved with Tapisseris check pattern, echoing the face plate.
Feature 3: Calibrated 5134 from Calibre 2120
Compared with the old RO perpetual calendar, the watch not only adds a week number display on the edge of the face plate, but also the moon on the moon phase uses a high-resolution printed realistic version, which is more compatible with aventurine discs. A more realistic effect of simulating a starry sky. The internal 5134 movement is modified from the classic 2120. The main modifications include increasing the size of the movement (this is also reflected in the larger case size), and then the perpetual calendar module is also installed on it. However, this modification also has more weekly calendar functions, so Audemars Piguet directly changed the model to 5134, no longer adopting the practice of adding a secondary number after 2120, because the function of the movement has made a deeper evolution.
