The observation watch for the wrist
With superior rate accuracy and eminent legibility, the RICHARD LANGE continues the tradition of scientific observation watches at A. Lange & Söhne. The 925 silver dial features the slender Roman numerals that were typical for scientific observation watches during Richard Lange’s epoch. In 1868, he was appointed director of the manufacture and advanced precision watchmaking with his insights and inventions.

The timepiece owes its precision to a balance spring developed and manufactured in-house that beats at a rate of 21,600 semi-oscillations per hour. The sweep-seconds hand is made of blued steel and contrasts well against the dial. When the crown is pulled, it stops instantly. This allows the watch to be set to one-second accuracy. Readily visible through the sapphire-crystal caseback, the sweep-seconds wheel train is integrated between the three-quarter plate and a separate bridge.
