Audemars Piguet autoscelton watch with original box

The watch in the image is an Audemars Piguet Royal Oak Double Balance Wheel Openworked in Black Ceramic.
Here are some of the key features:
Brand and Model: Audemars Piguet Royal Oak. The Royal Oak is Audemars Piguet's most iconic collection, known for its distinctive octagonal bezel secured by eight visible screws.
Material: The case and integrated bracelet are crafted from black ceramic, which is highly scratch-resistant and lightweight.
Dial/Movement: It features an Openworked (or skeletonized) dial, which allows for a view of the intricate movement inside.
Mechanism: It highlights the Double Balance Wheel mechanism, a patented Audemars Piguet innovation that uses two balance wheels and two hairsprings assembled on the same axis to improve precision and stability. This mechanism is visible through the dial.
Color Scheme: The overall aesthetic is dark and monochromatic (black ceramic case and bracelet), contrasted by the visible movement components, often featuring pink-gold-toned or ruthenium-toned bridges and wheels, and often with pink gold applied hour markers and hands (or black rhodium-toned hands for contrast, depending on the specific reference). The pink-tinged jewels are also visible.
