The Cartier Santos de Cartier Large is an automatic mechanical wristwatch powered by the in‑house Cartier calibre 1847 MC, offering standard timekeeping functions of hours, minutes, and central seconds, with a power reserve of approximately 42 hours. The watch features a square case with rounded corners measuring about 39.8 mm in width and approximately 47 mm in length, with a slim profile of around 9 mm, crafted depending on the reference in stainless steel, steel and gold, or titanium. It is fitted with a sapphire crystal, a seven‑sided crown set with a synthetic spinel, and is water‑resistant to 10 bar (100 metres), making it suitable for everyday wear. The dial is typically silvered opaline with Roman numerals, a railway minute track, and sword‑shaped hands, with certain references incorporating luminous material. The Santos Large is supplied with an integrated metal bracelet featuring Cartier’s SmartLink system for tool‑free sizing (steel models) and a secondary strap in leather or rubber, both equipped with the QuickSwitch system that allows easy, tool‑free interchangeability, combining practical functionality with the iconic Santos design heritage.
