First released in 2002, reference 25977ST became immediately a grail for Audemars Piguet aficionados as it reunites - from a technical standpoint - the chronograph and the tourbillon, two among the most beloved and sought-after horological complications, and - from an aesthetic standpoint - fits them into an oversized 44mm Royal Oak case, undoubtedly the most iconic design of the band, and one of the most immediately recognisable in the entire field.

Two versions have been made for the model, a more sporty one with blue dial and red accents, and the present monochrome black variation. The masculinity and elegance of the black dial - incidentally, perfectly legible thanks to the large white luminova markers - renders this timepiece a truly “all round” watch, as enjoyable and appropriate during a regatta in Porto Cervo as it would be at the subsequent black tie dinner.

Offered in unpolished condition and complete of all its original accessory, one can’t avoid but notice the value proposition of this lot, considering that its original retail price was circa a quarter of a million USD.
