Cartier's "Santos" was the world's first watch for aircraft pilots, released in 1904, and is popular for its historical background, unique square case, and design with a bracelet integrated into the lugs. It is also known for being a favorite of many famous people. In recent years, the "Santos de Cartier," a modern take on the classic design, has been gaining popularity and is highly supported by fans.

Cartier watches are highly popular among luxury watches, and are favored by many celebrities. Therefore, the chances of seeing someone wearing the same brand may be high. However, because Cartier has many models, the chances of choosing the exact same watch or model are quite low. The key to choosing a watch that you can enjoy for a long time is to choose a design that suits your taste.
