Beauty and brains combine in the classic styling of the 100XL Chronograph, a recent addition to the Santos series. Clean lines on the 38-millimeter stainless steel case are studded with screws on the square bezel, securing the scratch-resistant sapphire window. Roman numerals mark the time on the silvered opaline dial where three inset chronographs display seconds, minutes, and hours with stop/start functions at the flick of a button, and wrist movement powers the watch automatically. A date display window is positioned at four-thirty o'clock. The black alligator-leather band sports Cartier's patented deployment-buckle folding clasp. The timepiece offers a 330-foot water-resistant depth rating.
