The Richard Lange model is the manufacturers first observation watch for the wrist. It revives the Lange tradition of large observation pocket watches that in the early 20th century were used not only by renowned research institutes but also served as timekeeping instruments in scientific expeditions.

Precision measurement is ensured by the watch featuring a stop second option. When the crown is pulled out, the blued steel sweep center seconds hand and the balance are stopped thus allowing the watch to be accurately synchronised with a time signal. For further accuracy, the dial features outer 1/6th seconds divisions.

This model is also notable for its tribute to company founder Adolph Lange's first born son Richard Lange (1845 - 1932), who was committed to scientific progress in the domain of precision horology. He is accredited with the discovery of a metal alloy for watch springs for which he was granted Patent No. 529945 in 1930. With this monumental discovery, Richard Lange established the fundamentals for the alloy still used today to manufacture hairsprings in high-end mechanical watches.
