Wanguobiao was founded in 1868 with a history of 150 years.
1868, IWC introduced the first pocket watch. Since then, IWC has achieved a special position in many aspects of the Swiss watch industry and played an important role in the world watch manufacturing industry.
Thanks to the efforts of agents all over the world, IWC Worldwide Watch has achieved a 500% performance growth in the past three years, which has made the general factory fully expand the market in the Asia-Pacific region. 1998 in April, the new rice released by Basel made its debut in Asia in March, and it was released by telex, which shows that IWC attaches importance to the Asia-Pacific region.
Since the establishment of 1868, IWC is also the only watchmaker whose craft has not fallen victim to the industrial revolution. IWC never pursues mass production. Even today, it faithfully adheres to IWC's inherent concept of manufacturing a small number of high-quality watches. Therefore, every watch made by IWC is handled perfectly in the smallest place, which can be used for decades under good care and is widely collected by collectors.
1880, Johannes Lausingbach Fogg took over the company and inherited IWC's accurate, reliable and eternal watchmaking culture. After four generations of tradition, it has gradually become a classic model of watch manufacturing in Europe and even the world, and won the love of royalty, politicians, popes and leaders. By the beginning of this century, it was awarded the certification honor of the highest craft reputation by Schaefer Hauser, which symbolizes IWC's highest quality commitment.
