Audemars Piguet continued the expansion of the Royal Oak with the introduction of Reference 25977, a chronograph tourbillon launched in 2003 and produced until 2013 in very small numbers.

The present Royal Oak Tourbillon Chronograph is impressive in absolutely every sense, from its large 44mm case to the complications it houses.

Reference 25977ST became immediately a grail for Audemars Piguet aficionados as it reunites - from a technical standpoint - the chronograph and the tourbillon, two of the most beloved and sought-after horological complications.

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, skiing down the slopes of St Moritz or for a day at the office.
