In the late 19th century many watch manufacturers had the so-called jump hour watches in their range - among them renowned makers such as Lange & Söhne in Glashuette. One of the most proliferous producers of this watch type, however, was IWC, using a technology based on Joseph Pallweber's construction; Pallweber had taken out a patent on watches with jumping numerals in 1883.
