This limited edition of 100 pieces is made to honor the company's founder Robert Mühle, who established the company in 1869. It features a new complication in the form of a date hand, which is located in the second third of the module plate. The complication was first used in a pocket watch back in 1793, and it's a rare sight thanks to the popularity of date windows.
The date function is powered by the hour wheel. When the hour wheel rotates, it activates a ratchet wheel, which controls the date hand and makes one revolution around its own axis every 24 hours. Once every 24 hours, a cam on the ratchet wheel locks into the teeth of the hand wheel and moves the date by one day, a distance of exactly 11.61290 degrees.
