Cartier classic, Santos series watch! Compared with round watches, square watches are particularly unique because of their angular design. When it comes to classics among square watches, Cartier’s Santos is naturally on the list. Santos watches are not only square. A model among wristwatches, it is also considered to be "the world's first modern watch". The birth of the Santos series of watches is full of legend. At that time, Louis Cartier was working for his friend, the Brazilian pilot Albert Santos. Sir Dumont created a watch that can be worn on the hand to facilitate checking the time during flight. The first modern watch in history came into being. This watch is made of fine steel and has a frosted dial. It is equipped with sword-shaped blue steel hands and classic Roman numeral time scales, which are classic and eye-catching. The outer ring of the Roman numeral time scales is a track scale, which adds some retro features to the dial of the watch. There are 8 screws on the bezel, which is very recognizable. The side is brushed and the bezel is polished, making it suitable for both formal wear and casual style. The case has a slight curvature, which fits the wrist perfectly and is very comfortable to wear. The crown is blue. Natural spinel, paired with an American crocodile leather strap, matches the blue round gemstone inlaid on the crown, showing an elegant and refined gentleman's temperament overall; the bottom cover is engraved with Cartier's logo and Albert Santos Dumont's signature "S=D"; the outline is smooth, simple and elegant, very in line with the trendy taste of contemporary gentlemen.
