The early 19th-century marine chronometry inspired the movement.
In the classic configuration of precision watches, Twin barrels work in parallel to deliver stable power for much of their 56-hour indicated reserve.
The manually wound movement in 18-carat gold baseplates and bridges shows why the simplest mechanisms are often the most attractive.
This mechanism oscillates at a frequency of 21,600 v/h (3 Hz)
