I guess you all watched the auction for this
"GIRARD PERREGAUX "Casquette" 9931 a Led ANNI 70". Apparently unworn, working, like-new condition, with box and papers and hangtag, nice photos. It sold for "only" 1110€. Why not more? I had expected it to go for 1400€ minimum. Was it the Italian auction text? Wrong time (easter holidays)?
Compare this to
member h00bt's SS GP - quite worn (but still good), no box, no papers, sold for approc 806€.
