Description:
Richard Lange Referenzuhr (this model in Platinum) is strictly limited to 50 pieces.
The ZERO-RESTART function is very useful for stopping events of short durations. It is also ideal for synchronising watches and clocks at different locations: the actuation of the push piece synchronises the seconds hand of the instrument with that of a reference clock exactly when its hand passes the 60-seconds mark (“zero”).
This action “stores” the time of the reference clock and allows it to be transferred to other timekeeping instruments.
The RICHARD LANGE “Referenzuhr” pays homage to a stronghold of time measurement that played in important role in 19th-century Dresden: the timekeeping service of the Mathematics and Physics Salon.
As the “keeper of time”, this scientific institution was responsible for precisely determining the local time and making it available to the city’s population.
So in a sense, it was the predecessor of present-day atomic clocks and time signal transmitters.
But in those days, the correct time had to be calculated on the basis of astronomical observations.
The result was then transferred to a high-precision pendulum clock in the salon.
Then, this reference time was saved with especially accurate pocket chronometers and then “carried” Precision in the service of the sciences: the RICHARD LANGE “Referenzuhr”.
Referenzuhr translated from German to English, means " Reference Clock", so we can see that this watch pays direct homage to the Time-Keeping Service of the Mathematics and Physics Salon in 18th-century Dresden.
