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, which is how the Santos watch came to be. At that time, what were referred to as wristwatches were merely makeshift adaptations, essentially pocket watches strapped to the wrist, with the crown still positioned at 12 o'clock! Santos's groundbreaking design moved the crown to the 3 o'clock position and embedded a natural blue spinel in the winding crown, captivating countless consumers with its enchanting blue glow. Today, we present the latest upgraded version of the Santos from 2018, featuring a newly developed quick-release system that requires no tools-simply press gently with your hand to remove the strap. This patented technology is unique, with a 40mm case diameter, equipped with the original SW200 movement, sapphire glass, and 100m water resistance. It comes in the latest black box from the official store-perfect for gifting or personal use!
