I don’t have a watch that is the most sentimental to me that has the highest value among the watches I own. The watch with the highest value (that I owned, but now gone), was a Rolex Oyster Daytona Cosmograph from the mid 1980s. There was little sentiment involved with that one. None of the watches I have that might be up there in value at present, am I particularly attached to. I do have favourites to which I am attached, but these are not particularly valuable.
