Cartier Santos de Cartier Large Steel & Gold Watch W2SA0009

The Cartier Santos de Cartier Large Steel & Gold 39.8mm (Ref. W2SA0009) represents one of watchmaking’s most significant innovations as the first wristwatch designed specifically for aviators in 1904 when Louis Cartier created this timepiece for Brazilian aviator Alberto Santos-Dumont. The stainless steel case with yellow gold 750/1000 bezel combines precious materials with Cartier’s signature design language whilst the iconic squared case, exposed screws, and seamless integration of form and function honour the pioneering spirit that revolutionised personal timekeeping.

At 39.8mm with 9.38mm thickness through distinctive squared case geometry, this provides substantial presence whilst maintaining proportions that suit most wrist sizes through the 47.5mm length that accommodates the Santos architecture. The silvered opaline dial with blued-steel sword-shaped hands creates aesthetic refinement whilst the exposed screws transform functional components into distinctive design elements that challenged traditional watchmaking conventions.

The Manufacture Calibre 1847 MC delivers reliable 40-hour power reserve through Swiss automatic construction with hours, minutes, central seconds, and date display whilst the self-winding operation provides daily convenience. The mechanical movement represents contemporary evolution of the historic design that established wristwatches as essential equipment for modern life.

The innovative QuickSwitch interchangeability system enables seamless bracelet and strap changes without tools whilst the SmartLink bracelet adjustment allows resizing through integrated mechanism. The steel bracelet with second calfskin leather strap provides versatile presentation whilst the 100m water resistance covers practical requirements.

This Santos de Cartier Large Steel & Gold suits collectors seeking authentic aviation heritage with iconic design significance and proven manufacture movement technology. The two-tone precious metal construction and revolutionary 1904 legacy provide distinguished character whilst the QuickSwitch system and contemporary usability ensure practical luxury that honours Cartier’s fundamental contribution to modern timekeeping through perfect balance of historical significance and contemporary refinement.
