I too noticed those Zenith results, being that they were 4 or 5 times available market rate I wouldn’t rule out Zenith being the recipient, because I cannot think of another plausible explanation. Several tropical A384 sit on Chrono24 and remain unsold, and normal market rate (to secure a reasonably swift sale) for that one is probably £7k+ ish. Whilst buying from auction can make certain buyers pay a premium the premium seen makes zero sense, but I bet the seller is happy and unconcerned either way Reminds me of a period when there were some similar unexplainable results on Heuer Rindts, Orvis Mareographes etc etc back in 2015/2016...
