The World’s Thinnest Automatic Perpetual Calendar

Best Audemars Piguet Replica introduced the Royal Oak RD#2 Perpetual Calendar Ultra-Thin, a concept watch that claimed the title of being the world’s thinnest automatic timepiece featuring a perpetual calendar.

While the height of the Cheap Replica Watches (6.3 mm) and the movement (2.89 mm) remain the same as the RD#2.While the dial color — and matching subdials — remains an attractive shade of blue, AP has applied a detailed satin finish to the watch’s face.

The bracelet and case are made from titanium, while the bezel and bracelet links are built from 950 platinum. Just like with most Audemars Piguet Royal Oak Selfwinding Perpetual Calendar Ultra-Thin Replica designs, the case finishing features a blend of polishing and satin brushing.

So, how exactly did AP beat its former record? Over a five-year period, the brand explored ways to subsidize the watch from a three-story movement — standard for most perpetual calendars — to a single level by combining various functions into single mechanisms.
