DESCRIPTION
- Measure of All Things Time : the RICHARD LANGE “Referenzuhr”
With its ZERO-RESTART function, an innovative seconds hand resetting mechanism, the limited-edition RICHARD LANGE “Referenzuhr” enriches the line of observation watches dedicated entirely to precise time measurement. 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.

The actuation of a push piece above the crown causes its seconds hand to jump to zero and wait there as long as the push piece is depressed. During that time, a vertical disc clutch assures that the ongoing measurement of time is not interrupted – the movement keeps running. When the push piece is released, the seconds hand restarts instantaneously.This ZERO-RESTART function is very useful for stopping events of short durations.
