Audemars Piguet Royal Oak Golden Age.

Returning to Audemars Piguet's line-up in spectacular fashion is yellow gold.  The Royal Oak debuted in stainless steel, and was the first luxury sports watch ever to be made in steel.  Indeed Audemars did not produce the Royal Oak in any precious metals at all until 1977.

After an absence of some 5 years, yellow gold is back in the form of the Royal Oak Golden Age.  A perpetual calendar in the grandest style.

A cool blue dial bearing the manufacture’s signature Grande Tapisserie guilloché balances the warmth of the case and bracelet. Upon it, three sub-dials present the information from the perpetual calendar, while the fourth at six o’clock bears an astronomical moon phase display, which requires a correction just once every 125 years and 317 days. The week is indicated by a centrally mounted white hand, which points to the markings on the flange.

Powering the watch is Audemars Piguet’s Calibre 5134, a slightly larger version of the ultra-thin 2120 calibre aimed at providing a better fit for the 41mm case. At just 4.31mm thick, however, the new movement manages to keep the watch case’s height to a reasonable 9.5mm.

The watch will be available from the end of November for £65,500.
