A rare opportunity; auction 31 October 2020, 10:30 am CET: https://www.monacolegendauctions.com/auction/exclusive-timepieces-22/lot-111 There are some other decent pieces there.
I can only speak for myself but that's far too high a price range for me. The opportunity cost would be far too high. Mrs Junkie would have my balls for earrings if I spent more this year or even that much on a single watch!!
