This late 50's or 60's 18K Gold Watch is really a masterpiece. The band is almost 1 inch wide and 18K. The watch is covered with a jeweled case. There is 8 round single cut Diamonds approx weight .05 and 9 round Blue Sapphires measuring2.5mm, The wearable length of the inside band is a good 6 1/2. I am not sure if it can be made bigger. The case # 803100920 and vines and flowers worked into the case cover. The watch has a 17 jewell movement and attached to the is a 22.5 mm link 18K gold band with a hidden clasp and safety chain. I just recently had the watched clean and checked and the Wind-screw replaced. I was given an unofficial value of 5-10 thousand dollars. This is a lovely and beautiful watch and unlike any you have seen. If you go to beautiful places this is the watch for you. From Kansas to you.
