Audemars Piguet continued the expansion of the Royal Oak with the introduction of reference 25977, a tourbillon chronograph 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 stainless steel 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, one with a monochromatic black variant and a much more edgy variant like the present example. Sporting an energetic grand tapisserie dial in blue with red chronograph accents, the super-luminova brings the timepiece alive with its charming baby blue hues. Powered by the manual wound caliber 2889 beating at 21,6000vph, this giant provides up to 72 hours of activities. Highly collectible and a pleasure to admire on the wrist with the beating tourbillon, this present example from 2004 is further preserved in a pristine condition that will charm every collector.
