Fortunately for me, I've never experienced this emotion! I just started collecting last year and have only added to my collection. I have yet to sell any of my pieces. For those of you who have been doing this longer than I have, please share your moments of flipper's regret. What watch did you sell, why did you sell it, and what did you miss about it? Also, did you eventually buy it again? This should be fun! Please include pics!
