Historic Building Survey plaque: "The Watts-Robinson Building 1913. One of San Diego's earliest skyscrapers, this building is an excellent example of the Chicago School of Architecture. The marble wainscoting, tile floors, and brass ornamentation are complemented by the original, ornate lobby ceiling. Replacing the old Watts Building at the same location, the structure was first known as the New Watts Building and later the Robinson Building. The building was long a favorite of jewelers; at one time 70 occupied offices in the building."
