Cartier Panthere Gold and Silver Watch in size small 23mm

Cartier panthere in size small 23mm in gold and silver. Two rows of gold. Great condition with blue hands and dial. Purchased but don’t use as much as I should. Have extra link available. With box and red box with white inside is the original with the watched but purchased another more modern box to go with it. Unsure on authenticity of the new box. Questions welcome!
