Selfwinding Perpetual Calendar Ultra-Thin

The Royal Oak Selfwinding Perpetual Calendar Ultra-Thin is the thinnest automatic perpetual calendar timepiece ever made by Audemars Piguet. It comes with a movement that is 2.89mm thick and a casing that is 6.3mm tall. It was first presented as a prototype at the SIHH in 2018 as RD#2, and it has since been combined with titanium and 950 platinum for an elegant design and a reduced weight on the wrist.
