The year 2006 saw the launch of a new generation of automatic mechanical movements developed by the engineers and master-watchmakers at Piaget Manufacture. At the top of the range is the 800P, with central hour, minutes and seconds hands, large date, and two barrels guaranteeing a 72-hour power reserve. This 12-line movement, measuring 26.8 millimeters in diameter, generates the traditional frequency of 21,600 vibrations per hour (3 Hertz), and can be adjusted by a balance with screws. The 850P version displays small seconds and a second time zone on two sub-dials, complemented by a day/night indicator synchronized with the central time zone. Excellent readability was the guiding principle in the design of this movement. The expertly hand-crafted finishing, such as the engraving of the Piaget crest on the oscillating weight, nobly enhance the technical sophistication of this impressive horological feat.
