Hublot Champion 90 Senna Tourbillon

About this reference

The Hublot MP-06 Senna Act IV Titanium (reference 906.NX.0129.VR.AES13) was released in 2013 as a limited edition of 41 pieces, representing the fourth collaboration between Hublot and the Instituto Ayrton Senna. This reference is no longer in production. Collectors value the model for its manual-wind HUB6300 caliber, a skeletonized tourbillon movement comprising 237 components with a five-day power reserve. The 45mm tonneau-shaped case is constructed from grade 5 titanium, featuring a sapphire dial with the Senna logo at the 9 o’clock position and yellow accents on the hands and markers. On the secondary market, this reference typically commands prices in the mid-to-high five-figure range, often appearing between $60,000 and $90,000 depending on condition and provenance. This specific titanium variant was produced alongside King Gold and black PVD titanium versions, each also limited to 41 pieces to reflect Senna's 41 Grand Prix victories.
