IWC Schaffhausen, founded in 1868 by American watchmaker Florentine Ariosto Jones in Schaffhausen, northern Switzerland, is the perfect combination of Swiss watchmaking skills and advanced American production techniques. Jones' vision found the ideal environment and resources in Schaffhausen, making the establishment of IWC a successful example of the integration of high-end Swiss watchmaking with American industrial technology. IWC is known for technological innovation in the field of watches with high complex functions. The brand's Portuguese, Aviator and Marine timepieces all demonstrate a high degree of mechanical complexity and reliability. As early as the early 20th century, IWC developed the unique Pelaton winding system, an automatic winding mechanism that significantly improved the performance and durability of the watch. IWC has also made significant achievements in complex functional areas such as perpetual calendars, tourbillons and chronographs. In terms of design, IWC's style takes simplicity, elegance and functionality as the core, emphasizing the perfect combination of practicality and aesthetics. Its watch design usually features a clear dial, exquisite craftsmanship and a classic look. While the Portuguese series is known for its large dial and precise timing function, the Pilot series is popular for its ruggedness and high readability. The Marine timepiece series combines the technical characteristics of professional diving watches and is suitable for use in extreme environments, demonstrating IWC's relentless pursuit of perfect integration of technology and design.
