Cartier Santos starry sky is shocking! It took 2 years to develop the entire watch to the finished product, using the most advanced inlay technology. The strap uses an edge-less inlay process to make the entire watch look stunning. In order to achieve the edge-less effect, we have gone through countless attempts while maintaining the thickness of the original strap. At the same time, the perfect inlay effect must be ensured; 1. 316 stainless steel material, size 40mm, using stable imported West Rail movement, stable running time! 2. Swiss-made fired steel hands, equipped with blue glass anti-reflective white film/anti-glare/anti-handprint 3. Equipped with Cartier’s two practical inventions, the “SmartLink” bracelet adjustment device and the “QuickSwitch” strap quick replacement device, making the watch more comfortable to wear. The strap is very snug and comfortable! Welcome to taste! ,
