Piaget may be best-known for its ultra-thin mechanical movements, but it can also trace its history of developing quartz movements back to the 1970s.
In fact, its first quartz movement was created 40 years ago in 1976, an anniversary that the company celebrates by adding quartz technology into the mechanical movement of the Caliber 700P, which delivers the accuracy of quartz with the traditional watchmaking of an automatic.
Combining a mechanical caliber with a quartz regulator in the Emperador Coussin XL concept watch highlights two perfectly-mastered skills forming part of the Manufacture’s heritage, the company says.
The high frequency of the quartz, vibrating at 32.768 Hz, controls the speed of rotation of the regulator and of the gear-train.
This allows for a very high degree of accuracy and offers greater resistance both to magnetic fields and to the negative effects of gravity.
The limited edition is presented as a shape within a shape: a cushion-shaped 46.mm diameter case in white gold sits within rounded bezel. Just 118 pieces were made
