Hi, I wonder what's the value of this watch: Longines, year 1911, pocket watch in 18K Gold, equipped with a movement calibre 9.77. Number of watches like this made by Longines: only 1, unique. For other details see image. Thanks.
The watch appears to have been modified by a jeweler. I'd imaging something like this has a value that is highly dependent on the value of the gold & stones.
