Hey guys, I'm looking to buy myself a pre owned/ vintage speed master while I'm on vacation in LA. There's one in particular that has caught my attention http://www.secondtimearoundwatchco.com/watches-for-sale/a/a/10288 it's from 1976 and the store is reputable with a full two year warranty and very good reviews. They also have another speedy but it is a modern one from 1993 http://www.secondtimearoundwatchco.com/watches-for-sale/a/a/10301 and one more http://www.secondtimearoundwatchco.com/watches-for-sale/a/a/10079 from 1998 They all look to be in very good shape. What are you opinions of the asking prices? I like that this shop is very reputable and has the 2 year full warranty. One more question is how much more usable is a newer speed master than one that is 40 years old? Can the newer one take more abuse? More water resistance? I plan on wearing the watch every single day, and the vintage one from the 1970s is mega cool to me. Anyways thanks for your advice!
