Established in Paris, France in 1847, Cartier is a brand held in such high esteem by jewelry and luxury watch connoisseurs. So much so that it was labeled as "the king of jewelers" by King Edward VII of England. The quality of workmanship that goes into each masterpiece is without equal and the launch of the Cartier Tortue in 1912 proved this. Whether with plain or pave diamond bezels, the line offers varying degrees of elegance with its 18k gold or platinum tonneau case and silver or openworked dial. The Cartier Tortue can be a simple classic with black Roman Numerals and blued steel hands indicating the time, or downright stunning with complications like perpetual calendar, multiple timezone, or minute repeater, just to name a few. For some models, the astounding visual of a Cartier Tortue continues all the way to its transparent case back as it gives one a pleasant view of the movement.
