Audemars Piguet Equation of Time Platinum Skeleton

This has always been one of my favorite AP’s. Calendar complications are AP at its best, and this is the best of the best.

Featuring a perpetual calendar with equation of time, and sunrise and sundown dials, the complication is actually quite usable (what time is sunset tonight? is one of my most often asked Siri questions). The platinum case is of perfect proportions and the skeleton work is pure craft. Check out the engraving of the back of the movement!
