Two dial designs

The Richard Lange model is available in two different dial designs: The Richard Lange with classic minute scale and slim Roman numerals is reminiscent of the traditional "Great Observation Watch", which marks a high point in the development of precision watches by the watchmaker. The second dial design is a so-called regulator dial. In order to be able to read his timepiece easily in poor light conditions, the German natural scientist Alexander von Humboldt decided in 1799 on a watch whose hour, minute and second displays are arranged separately in a triangle. This was extremely important during his trip to Latin America, as the chronometer was one of the most important scientific instruments at the time. The precise time was essential for determining the position of the watch and for various scientific measurements. Two special modern Richard Lange timepieces were also equipped with this special dial: The Richard Lange "Pour le Mérite" and "Terraluna".

Richard Lange "Pour le Mérite"

What is particularly impressive about this watch is the sophisticated mechanism inside. The sapphire crystal back allows a wonderful view of the chain and scroll. The case of the Richard Lange Pour le Mérite is made of white gold and has a diameter of 40.5 mm. The black regulator dial and the golden rhodium-plated hands and numerals create a unique contrast. The "Pour le Mérite" lettering enhances the overall appearance of this A. Lange & Söhne Richard Lange.

Richard Lange perpetual calendar "Terraluna

With this special watch, you can read the phases of the moon through the sapphire crystal case back - but of course only when it is no longer worn on the wrist. The model with regulator dial also displays the position of the sun and moon. There is hardly any other watch in the world that can display this phenomenon.
