Overview

The Santos de Cartier Large in reference WSSA0018 presents the house's storied square-case silhouette in a 39.8 mm stainless steel case, paired with a silvered opaline dial dressed with Roman numerals. Powered by Cartier's in-house Calibre 1847 MC, it occupies a confident position within the dress-watch segment while retaining the Santos line's unmistakable architectural character.

History

The Santos lineage traces back to Louis Cartier's early-twentieth-century commission for aviator Alberto Santos-Dumont, making it one of the oldest named wristwatch lines in horological history. The large-size WSSA0018 variant entered production in 2021, continuing a modern chapter of the Santos that Cartier relaunched with updated proportions and the QuickSwitch interchangeable-strap system. Collectors regard the current generation as a thoughtful balance between heritage aesthetics and contemporary wearability.

Notable points

  • 39.8 mm stainless steel case preserves the Santos's signature exposed-screw bezel and integrated bracelet design.
  • Silvered opaline dial with Roman numerals reflects Cartier's longstanding preference for legible, jewellery-influenced dial architecture.
  • Calibre 1847 MC is an in-house movement, underscoring Cartier's commitment to manufacture-level production in the modern Santos era.
  • The Santos line is widely recognised as one of the earliest purpose-built wristwatches, lending the reference strong historical resonance.
  • QuickSwitch strap-change system, introduced with the relaunched Santos generation, allows tool-free alternation between bracelet and strap.
