DECORATION IN PERFECTION.

A glance through the sapphire-crystal caseback reveals the rich inner life of the 1815. Its newly developed manufacture movement displays all of the characteristic quality hallmarks of Saxon watchmaking art-istry. The three-quarter plate made of untreated German silver is an instantly recognisable Lange signature element. It showcases five screwed gold chatons that with their blued screws and ruby-red bearing jewels create a noble visual contrast against the backdrop
of the regular Glashütte ribbing. 

Located immediately adjacent to the three-quarter plate, the hand-engraved balance cock is decorated by a Lange master using free-hand techniques that make each 1815 a genuine, one-of-a-kind treasure. According to Lange tradition, this component carries a whiplash spring that in the calibre L051.1 movement is precisely concentric with the balance-cock mounting screw.

LOOK OVER THE WATCHMAKER'S SHOULDER.

INGENIOUS INTERACTION.

Carried by the balance cock, the classic screw balance beats with a frequency of 21,600 semi-oscillations per hour; it is adjusted in five positions. Interacting with the pallet lever and the bilaterally polished escape wheel, it governs the rate of the manually wound movement. When fully wound, it has a power reserve of 55 hours. The stop-seconds mechanism makes it possible for the owner to accurately
set the time.
