Not sure on the correct forum for this question; my apologies if I guessed wrong.
My father is getting up there in years, and is giving away many of his treasures. Knowing that I appreciate mechanical things, he has given me his collection of fine watches. I’m curious about on-line resources to try to find out more about these ingenious devices; what are they worth, how can they be restored, how best to care for them. (Or, for that matter, resources that are NOT on-line.) I have no intention of selling these items, but I would like to know if they have significant value. They include Bulova, Elgin, Omega, and Waltham timepieces, both wrist and pocket varieties. Most of them date to the seventies or earlier.
If anyone knows of a good on-line or off-line resource for info about such items, I would appreciate a link or referral. My own Googling has turned up very little. Thanks, gang!
