Just like its famous namesake, the RICHARD LANGE watch family is fully devoted to the scientific facets of horology with a focus on the utmost degree of precision. It has its origins in the understanding that the accuracy of a timepiece reflects the competence of the master. At A. Lange & Söhne, this insight dates back far into the 19th century. With its resettable subsidiary seconds, the RICHARD LANGE “Referenzuhr” continues this tradition.
