Three small seconds hands and one large seconds hand, all custom-made as single pieces with solid needle sleeves, and the needle caps are in a mushroom-shaped round head design. The ceramic ring has been upgraded with a platinum-coated film to prevent color change, and the font thickness has been updated. Say goodbye to the “dead white” color that turns black in the market. The glass is made of fully transparent sapphire with no edge visual effect.
