The Cartier Santos de Cartier watch can be considered the world's first true wristwatch, boasting a history of over a century. In 1904, Cartier introduced a watch that could be worn on the wrist, naming it after his close friend, Alberto Santos-Dumont. This marked the origin of the Santos watch. At that time, what were referred to as wristwatches were merely makeshift timepieces, essentially pocket watches strapped to the wrist, with the crown still positioned at 12 o'clock! Santos pioneered a design that placed the crown at the 3 o'clock position, featuring a natural blue spinel on the winding crown, whose enchanting blue glow has captivated countless consumers to this day.Today, we present the latest upgraded version of the Santos from 2018, featuring a brand-new quick-release mechanism that requires no tools. With just a gentle press by hand, you can easily detach the strap. This patented technology is unique, with a 40mm case diameter, equipped with an imported movement, a sapphire crystal, and water resistance up to 100 meters. The images shown are of a top-tier replica!
