Precision in one-second intervals
The RICHARD LANGE JUMPING SECONDS unites elaborate precision mechanisms with a regulator-style dial of exceptional design that shines the spotlight on the smallest of the three units of time, the seconds, in terms of technical finesse and aesthetic appeal. For the first time, three mechanisms are integrated in the watch that perfectly complement each other: the constant-force escapement, the jumping seconds mechanism and the ZERO-RESET mechanism. Hence, the timepiece establishes benchmarks in rate accuracy and legibility.
The RICHARD LANGE JUMPING SECONDS comes in two versions: one in 750 white gold with a black dial, and a limited-edition model of 100 watches in white gold featuring a 750 pink-gold dial.
A prominent dial with historical inspiration
The RICHARD LANGE JUMPING SECONDS boasts a regulator-style dial with an extraordinary geometry of displays. All time indications are arranged in triangular fashion. The largest, centrally positioned circle displays the seconds while the two smaller ones below indicate the hours and minutes.
This prominent arrangement was inspired by chronometer No. 93 crafted by Johann Heinrich Seyffert, a gifted watchmaker who in the late 18th century established the fundamentals of precision timekeeping in Germany.
A small triangular indication at the intersection between the hour and minute circles switches to red ten hours before the power reserve is depleted, thus delivering a reminder to soon rewind the watch.
Three perfectly matched mechanisms
Three groundbreaking mechanisms are integrated in the RICHARD LANGE JUMPING SECONDS that perfectly complement each other: the constant-force escapement, the jumping seconds mechanism and the ZERO-RESET mechanism.
The constant-force escapement assures that the watch is powered with a constant force during the entire power reserve, resulting in superior rate accuracy. To supply the required energy, an impulse is generated every second. This impulse is also used for the jump of the seconds, exactly 60 times per minute.
The ZERO-RESET mechanism is equipped with a multi-disc clutch: when the crown is pulled, the seconds hand instantly jumps to the zero position, making time setting with one-second accuracy possible. The choreography of the trinity of mechanisms can be admired through the sapphire-crystal caseback. When the crown is pushed home, the seconds hand engages with the going train, the balance wheel is released and the watch immediately begins to run again.
Movement L094.1
The manually wound 390-part calibre L094.1 is assembled twice and incorporates many traditional elements. The remontoir spring of the constant-force escapement and the balance spring are manufactured in-house and can therefore be optimally paired with the movement. The elaborate finish of all components complies with the manufacture’s high standards when it comes to artisanal perfection.
The sapphire-crystal caseback exposes the evocative composition of typical Lange quality hallmarks to view, such as the hand-engraved balance cock, screwed gold chatons, blued screws as well as the three-quarter plate made of untreated German silver which is lavishly embellished with decorations and polishing techniques.
