I missed it because I was not looking in July of 2020. Yes, whoever bought the watch did get a great deal... no question. But, how much?
If you use Speedmaster101's price chart a 2998-2 head with a base 1000 bezel in fair condition is worth 18k, and in good condition it's worth 25,000K. I don't see the watch as in very good condition, 45K,... maybe others do? Tropical dial... I don't know. IMO you are looking at a watch worth somewhere between 18 and 25K, closer to 18K. Buyer, assuming he/she paid for shipping, sales tax, VAT, customs, probably spent closer to 13K+... still a phenomenal deal...lucky him.
Where were you guys? I mean it's Christies, not some unknown auction house in the middle of nowhere, but Geneva.
