The case is white gold marked 14k - D&A. Di Vincenzo & Ariente and the band is marked 1/20 10k G-F or Gold Filled and made by Kreisler. It's a great looking band and highlights the beautiful piece. The dial has a discoloration mark at the 2 and 3 number. The watch winds and runs but not consistently nor keeps accurate time. The wooden Le Coulter box is probably not the original but well made.
