Hi, The previous thread on "What Watch" has steered my interest in things that go tick. Now, theoreticaly not only would collecting watches give me a few interesting things to wear but would also be an investment for the future. I think I'll go for 70's - 80's watches manly with a light dusting of other era's ) Can any one suggest any good books on the subject? Can investing in watches be a good investment? Cheers in advance?
