Audemars Piguet Royal Millenary 4101 15350OR.OO.D093CR.01 Skeleton Dial watch, a fine gold crown, has an unusual architecture under its oval shape (not all oval cases can be loaded with oval movements). First, the main time dial, the time dial, is no longer centered on the dial, but placed on the off-center oval dial, displaying hours and minutes using Roman numerals. On the lower left, a small circular dial and a small seconds dial with track lines are arranged in an overlapping manner. This elaborate design has changed the mediocre layout of the original time and second hand. Now the whole time and minutes tend to the layout on the right side of the dial, and the left side is empty. There must be a finishing touch to balance the whole dial. 4101 here shows the heart of the movement-escapement mechanism, which is basically made of 22K gold, gold escapement splint and gold Gyromax weight balance wheel. Interestingly, the motherboard under the balance wheel is specially hollowed out, which easily gives the impression of tourbillon.

The highlight is the two-way chain 22K gold rotor fixed by ceramic bearings. The movement has 34 drills and the power reserve is 60 hours. The power of the automatic movement is enough for daily use.
