Welcome to my Top Swiss Wristwatches Boutique! Founded by Louis-François Cartier in Paris in 1847, this name is icon of haute style forewer. Cartier is regarded as one of most prestigious jewellery manufacturers worldwide. In 2018, it is ranked by Forbes as the world's 59th most valuable brand. Cartier has proud, long history of sales to royalty; the watchmaker has perhaps the most enviable historical claim of any watch brand: purveyor of the first men’s wristwatch, the Cartier Santos, in 1911. Sure, Rolex and others have some notable technological innovations, but Cartier started it all. As the story goes, in 1904, Brazilian aviator Alberto Santos-Dumont complained to friend Louis Cartier about the unreliability and impracticality of using a pocket watch while flying. Cartier designed a flat wristwatch with a square bezel and gave it to Cartier, and the watch eventually caught on with other customers. Thus, the first mass-produced men’s wristwatch (and first pilot’s watch; take that IWC!) was born. While there’s debate about the first humans to take flight — Santos-Dumont or the Wright brothers — there is no debate about the first men’s wristwatch. What also can’t be debated is that Santos-Dumont became the first person to be filmed in an airplane flight in November 1906 when he took flight for 21.5 seconds, with a Cartier watch on his wrist. Ronde Solo de Cartier wristwatch was first created in the late 1930s and has endured several iterations. It's known for its large, circular case, inward-bending lugs and traditional roman numerals, all of which give it a timeless charm that is understated and effortlessly sophisticated. Stemming from the days of Louis Cartier, the Ronde de Cartier is defined by Roman numerals, blue sword-shaped hands, and a sapphire cabochon.
