Hand made perpetual calendar with instantly jumping central indication of all calendar data, including leap year indication.
The „QP 1“ has all hands located on one central axle. The available space on the round dial is optimally used by concentric circles.
All indications are clearly arranged and well readable.
The watch has a power reserve of 36 hours and its case is made from 18-carat gold or platinum.
All parts of the mechanism, dial, hands and case are developed and made in house.
