The Cartier Santos de Cartier watch can be said to be the world's first true watch. It has a history of a hundred years. In 1904, Cartier launched a watch that could be worn on the wrist and was named after his close friend Santos de Cartier. Named, this is the origin of the Santos watch. The so-called "watches" at that time were just some "expedient" watches, that is, the pocket watch was tied to the wrist, and the crown was still at the 12 o'clock position! Santos' pioneering design places the crown at 3 o'clock and inlays a natural spinel on the head. The blue light has captured the hearts of countless consumers to this day. What I bring to you today is The latest upgraded version of Santos in 2018, a new technology upgraded quick-release device, no tools are needed, the strap can be removed with just a tap of bare hands, unique patented technology, 40mm watch diameter, equipped with original SW movement, sapphire glass, 100m Waterproof, shipped with the latest black box from the counter! Great gift for personal use,
