I pick up the mens wristwatches only unless its a gold case ladies watch for the right price. I did at a Knights of Columbus sale snatch up a mens 1950's Breitling Chrono for 10 bucks and sold for over 900. The most I gave for a mens watch was a Mens wristwatch late 1930's 18K Audemars Piguet with 14K mesh band. I gave 1200 for it and sold it for over 3400. I've been blown away on some of the amount of money I've got for these 1970's and early 1980's Seiko, Citizen and Casio LCD watches. Two month ago I got a stainless Seiko LCD Silver Wave for 5 bucks and it did 230. The buyer from the UK said he'll buy any others like it I find and gave me a list to look for he even wanted the plastic one from the 70's early 80's era. Stick to Mens wristwatches, most great looking and cool ones will sell, focus on the brand name a Timex not gonna sell well. I collect the old windup's and automatics and wish I hadn't sold some I had in the past. I stated ebay selling of my collection of vintage watches and wish now I'd kept some of the better ones, as they are hard to find at a good price these days. Not that I'll get a fortune out of my Longines, but this broken Longines did okay recently and that helps in keeping the brand name strong

Study the Real vs. Knock Offs. You will see the difference in the quality of construction in every detail. I've seen some very knowledgeable collectors get jipt. Go to a high end jewelry stores and study the real deal in every way. The pins in the bands, the hands, the dials and case will be all made in the geatest detail, If its in a place like I mentioned I look for vintage watches and you find a Rolex, Omega, Tag Heuer or any well known expensive name its 99.9% fake. Pawn Shops are real good at putting those out and many estate sales seed the place with fake crap also.
