The repeat mechanism is locked during the strike in passing and is released, as usual by a slide in the band. However, unlike most repeaters, this does not power the repeating work, the power in the barrel for the striking-train is sufficient for several operations of the minute repeating. Movement and strike are wound by turning the winding button in opposite directions. According to the records, Lange & Sohne made only four watches with grand and petite sonnerie striking and minute repeating. This watch appears to be the only example known in a Louis XV case. It cost 4000 Marks in 1925, making it the most expensive watch of its class and amongst the most expensive Lange watches ever made. The watch was sold by Lange again in 1934 to Adolf Lunser, a Berlin company who were the official suppliers to the German Government.
