The Cartier Santos de Cartier WSSA0030 is one of the core modern Santos references, with the model's square sport-watch design in a large stainless steel case. Its blue dial gives it a cooler, more current look, paired with a matching steel bracelet. The automatic movement includes a date, keeping the watch practical without drawing attention to the mechanics. At 39.8mm by 47.5mm and 9.08mm thick, it has broad wrist presence but stays notably slim.
