It's all good guys- there is a never ending stream of this stuff out there- another just like it (or better) will come along. If this volitle watch market has taught us anything, it's that we can make predictions and speculations on value all we want based on facts and data- but there will always be people who will buy based on emotion and escalate a bidding war. Whoever bought that one got a nice watch and I'm glad they got a prize.
For me, I know what these things are "worth" based on research and experience and will patiently wait for the right one to come along.
On that theme- another watch for which I happily paid $700 for a similar example ended yesterday- I put in a low ball bid and got it for $288. Talk about unpredictable markets!
