In 1884, IWC manufactured the first so-called Pallweber pocket watches. These innovative timepieces displayed the hours and minutes in digital format with large numerals on rotating discs. In the anniversary year, IWC honours this pioneering achievement with the IWC Tribute to Pallweber Edition “150 Years”. This pocket watch is limited to just 50 watches and has an 18-carat red gold case, a white dial with a lacquered finish, and white display discs. As a reference to the design of the historical Pallweber watches and a tribute to F.A. Jones – the American watchmaker who founded IWC – the windows of the digital display are labelled as “Hours” and “Minutes”. The IWC-manufactured 94200 calibre advances the display discs by using a separate wheel train with a barrel of its own. The fact that the flow of power in the main wheel train is uninfluenced, guarantees a precise rate and a 60-hour power reserve.
