1, material: at present, the material of domestic watches can not meet the standard of Swiss high-end watches: for example, 904L for Rolex steel can resist dilute sulfuric acid, which is more corrosion-resistant than the commonly used 3 16L. Swiss watches are excellent in color, elasticity, beauty and luster polishing.
2. Technology: 1994 to 2009, Swiss watches applied for more than 170 patents in China, while domestic watches only applied for 5 patents of Seagull and Fiyta. These patents cover almost all key technologies of watches: hairspring, escapement, calendar, moon phase, perpetual calendar, tourbillon and so on.
3. Technology: The technology of Swiss high-end watches is better than that of fine watches. Swiss high-end watches strive for perfection from design to production.
