Elite men with an annual salary of one million generally wear high-end brands of watches, such as Rolex, Omega, Patek Philippe, Cartier, Audemars Piguet and so on. These brands of watches are not only excellent in workmanship and reliable in quality, but also have a high sense of fashion and taste, which can show the status and taste of these elite men. At the same time, these brands of watches often have complex mechanical structures and functions, such as timing, timing, perpetual calendar, flying back and world time, which meet the needs of elite men who need efficient timing and time zone conversion.
