That Esquire article about TAG's return to F1 has a number of minor mistakes in it. Which is why I wonder if they might've confused which of Senna's personal watches is now in the TH Archive.
However, the caption was very specific to his S25.706C which was last auctioned in 2007. If it was never auctioned again, and TH does indeed now own it, it means it likely changed hands via a private sale. Which raises the question of why wasn't it auctioned? Because I would think the watch today would go for a lot more than $69,000 USD.
Whatever the case, I still have doubts. Would be good if someone who visited very recently can confirm, like
