Audemars Piguet definitely presented one of the most interesting timepiece of this SIHH with the RD2. This ultra thin perpetual calendar is still a concept watch, but it should come out probably next year. The team of Audemars Piguet have reimagined some key components of the traditional QP in order to achieve this spectacular result and reduce the overall size and thickness of this movement. But the brand showed us some other watches as you will be able to enjoy in this video report.
