In 2015, Cartier released the Calibre de Cartier 38mm, a smaller version of their popular collection. It runs on the same in-house caliber 1904-PS as its larger counterpart. The dial is more traditional, but still stylish. The WF100013 model boasts a pink gold case, a diamond-studded bezel, a silver dial, and a semi-matte brown alligator strap.
