Material: High-purity ceramic, nano-sintered, high hardness, scratch-resistant, and not easy to discolor. • Engraving: Laser deep engraving, platinum powder filling (non-electroplated), strong texture, does not turn black, and does not fade.
Lugs/Endlinks: The endlinks are molded independently and seamlessly connected to the case; the top is flush with the case, the tail is slightly concave, and the bottom is recessed
Case back: The steel version has a delicate brushed finish; the precious metal version (rose gold/white gold) is engraved with 750/Saint Bernard dog head, with clear and deep engraving; the new 4131 case back has a wider flat surface, making it more comfortable to wear on the wrist
