Cartier Santos WSSA0013 Blue Dial Watch, opens the mold 1:1, truly interchangeable with the original accessories. Waterproof to a depth of 10 bar (about 100 meters) and equipped with Cartier’s two practical inventions, “SmartLink” bracelet adjustment device and “QuickSwitch” strap quick replacement device. The case has been carefully polished and feels smooth. The square sapphire glass in the middle is transparent and flawless, so it is simple and convenient to look at and clear at a glance. The blue dial is very attractive. The radial dial shows a gradual change design with deep center and shallow outer edge, just like from shallow sea to deep sea. The outer ring of the dial is a silver Roman numeral time scale, with clear and bright fonts and slightly raised three-dimensional effect. The middle hand is designed with three hands, the hour hand and minute hand are sword-shaped hands, and are filled with luminous materials, so that the time can be easily checked at night. The calendar window with white characters on black background at 6 o’clock position makes the whole dial more natural and perfect.
