I received one as a bonus from my boss many years ago. From what I understand he got it in a Pawn Shop, had it tuned up, added a white Gold Bezel and jubilee band. He paid about $1000 for the whole deal.
The last time I had it in a repair center for a tune up (once every 5 years for me) it was appraised at $2000 after the tune up.
I wear it daily, its understated, its scratched up and its become part of me.
