Early in their respective careers, Brazilian aviator Alberto Santos & Louis Cartier collaborated on a watch that Alberto could wear while flying. Hence, the Santos wrist watch was born with emphasis on wrist-wearable. It was the first of its kind to be designed specifically for the wrist. The watches to follow in the Santos line carry this heritage with them. The dial is white with blue roman numeral indices & the signature screw down bezel is here as usual with the Santos.
