I have been researching a Longines watch given to me by my uncle who was the doc for the jocks. He was given a watch from eddie arcaro. It is round and thin, the face is encircled in 44 diamonds, the second hand is at the bottom of the face. The case is 18k WG. The back is engraved from Eddie Arcaro. The velvet band reads longines on one side and the other side reads?? grand prizes and ?? gold medals. It is in a navy blue box with Gruen the Precision watch on the outside and Princess by Gruen inside. I believe the watch was made in 1930-1950. Any idea of the date or value of this one? Thanks JW1
