Since its introduction in 1932, the watch belonging to the Patek Philippe logo collection has never been outdated. The watch has real-time recognizability: round, ultra-classic, with Arabic numerals only minimalist style dial, slender hands and will not be confused "Paris studs" bezel. Decades of years, of course, brought small changes and new details, but the nature of the watch has never changed. Although Patek Philippe's more sophisticated features are more prestigious, the name of the watch is still a symbol of classics and taste that Patek Philippe involuntarily associates with. Calle Zhuohua the name is also reminiscent of Karel Zhuohua cross and its four stylized iris pattern: once Calle Zhuo Hua Knight emblem, the medieval class once unique in the Holy Spain period, is now Patek Philippe's coat of arms. Another reason the watch occupies such a special place in the history of Patek Philippe is that it appears right at the moment of the brand's "rebirth." The company struggled for a time in times of trouble, but after it was acquired by the Stern family in 1932, it went all the way to success.
