The Popular Fake Royal Oak #RD2, known as the world’s thinnest self-winding perpetual calendar. Impressively complex inside and very familiar outside, we knew this piece was not going to remain a concept for long…
Inside a very familiar Royal Oak case measuring 41mm in diameter but only 6.3mm in height was a newly developed movement based on the old Replica Watches calibre 2120 base with a brand new QP mechanism integrated into the movement in order to gain space.
Its case (still 41mm x 6.30mm) is now an “IP”, meaning a brushed titanium base – for the central case, caseback, crown and most of the bracelet – with some polished platinum accents – bezel and bracelet central links. The RD#2 prototype was fully made of 950 platinum and was very, very heavy on the wrist.
The new Audemars Piguet Royal Oak Selfwinding Perpetual Calendar Ultra-Thin retains the dimensions of the RD#2. The Copy Audemars Piguet case is 6.30mm in height, which is 3.2mm less than a regular Royal Oak Perpetual Calendar, itself already not a thick watch.
