That's not even the same reference. The one in your C24 link is a 6145 with date only. The one highlighted in this article is a 6146 with day and date. Also, the brushed finishing on the top surfaces of the case in the C24 listing is a huge contrast to the polished top surfaces of the one highlighted in this article. They are two different watches.
Looks like winner of the 6146-8020 read your piece after and is trying to get rid of it immediately ðŸ¤
