A STEP FORWARD IN PRECISION WATCHMAKING – STANDSTILL.
The V-shaped arresting spring of the patented stop-seconds mechanism is just as ingenious. When the crown is pulled, the spring’s two dissimilar arms gently come to rest on the classic screw balance and thus halt the tourbillon. Its geometry is optimised to assure that it works in any position of the balance and any orientation of the tourbillon cage. Moreover, the potential energy of the hairspring is preserved so that the balance automatically starts oscillating again when the crown is pushed home. To prevent any unintended engage-ment when the balance is stopped and released, the two ends of the braking spring are bent outward.AESTHETICALLY FLAWLESS WATCHMAKING ARTISTRY.
Apart from its technical refinements, the movement features all of the typical characteristics of Lange’s acclaimed watchmaking artistry, such as the captivating Glashütte ribbing on the three-quarter plate and the seductive interplay of colours of the screwed gold chatons.
