The Cartier Santos de Cartier watch can be considered the world's first true wristwatch, with a history spanning 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 the origin of the Santos watch. At that time, what was called a wristwatch was merely a makeshift creation, essentially a pocket watch strapped to the wrist, with the crown still positioned at the 12 o'clock mark! However, Santos pioneered a design that placed the crown at the 3 o'clock position and adorned the winding crown with a natural spinel, whose enchanting blue glow has captivated countless consumers to this day.Today, we present to you the latest upgraded version of the Santos from 2018, featuring a brand new quick-release system that requires no tools. With a gentle press by hand, the strap can be easily detached. This patented technology is unique, with a 40mm case diameter, equipped with an original SW200 movement, sapphire crystal, 100m water resistance, and packaged in the latest black box from the official store! It is a perfect gift for personal use or to give to others.
