The Cartier Santos de Cartier Large Model reference WSSA0013 is a contemporary luxury sports watch that honors the historical legacy of the first purpose-built pilot’s watch from 1904. This model features a 39.8mm stainless steel case with a slim profile of approximately 9.1mm to 9.4mm and a lug-to-lug distance of 47.5mm. Its signature aesthetic is defined by a square case with rounded corners, a polished bezel secured by eight exposed screws, and a seven-sided crown set with a blue faceted synthetic spinel. The standout feature is the sunray-brushed, graduated blue dial that darkens toward the edges, accented by mirror-polished Roman numeral hour markers and luminescent sword-shaped steel hands. It is powered by the in-house caliber 1847 MC automatic movement, which operates at 28,800 vibrations per hour and provides a power reserve of roughly 42 to 48 hours.
In terms of complications and functionality, the watch includes hours, minutes, central seconds, and a discreet date window located at the 6 o’clock position with a matching dark background for visual consistency. It is engineered for modern utility with a water resistance rating of 100 meters, making it suitable for light swimming. A key technical highlight is the QuickSwitch interchangeability system, which allows the wearer to swap between the included stainless steel bracelet and the navy blue calfskin strap without tools. The steel bracelet further features the SmartLink adjustment system, enabling the removal or addition of links using only a fingernail to depress release buttons on the underside of each link.
General reviews of the WSSA0013 often praise its refined and versatile design, noting that the blue dial offers a sportier and more casual alternative to the traditional silver Cartier palette. Owners frequently highlight the exceptional comfort of the case shape and the ingenuity of the proprietary bracelet systems. While the watch is widely celebrated for its heritage and build quality, some critics point out that the polished bezel is prone to visible scratches over time. Additionally, some enthusiasts have noted that the legibility of the mirror-finished numerals can be challenging in certain lighting conditions and that the power reserve is relatively modest compared to some modern competitors.
