The three-part regulator dial of the RICHARD LANGE TOURBILLON “Pour le Mérite” was inspired by a precision chronometer crafted by Dresden master watchmaker Johann Heinrich Seyffert. An inimitable feature of this timepiece is the aperture in the subsidiary-seconds dial through which the tourbillon can be observed.
An aperture in the subsidiary seconds dial exposes the steadily rotating tourbillon. To assure the unambiguous readability of the hour, a segment of the hour dial bearing the numerals VIII, IX and X flips into view at precisely 6 o’clock. It retracts again at 12 o’clock, when the pivoting dial segment is no longer needed.
The patented stop-seconds mechanism can also be observed in the dial aperture. When the crown is pulled, a V-shaped arresting spring instantly stops the tourbillon. Developed by A. Lange & Söhne, this mechanism makes it possible for the very first time to block a tourbillon in any cage orientation and regardless of the angular position of the balance. This allows the time to be set to one-second accuracy.
