This watch is the Santos de Cartier, specifically the large model with a gradated brown sunray-brushed dial, often referred to as the "Tiger Eye" or "Chocolate" dial.
The Santos de Cartier is a modern iteration of one of the world's first pilot watches. This particular model, released around 2024, is noted for its distinctive warm "Tobacco" or "Tiger Eye" brown dial that transitions from a lighter center to a darker perimeter. It retains classic Cartier design elements, such as the square case with visible screws on the bezel and bracelet, while incorporating modern user-friendly features like the tool-less SmartLink and QuickSwitch systems.
