In 1884, IWC manufactured the first so-called Pallweber pocket watches. These innovative timepieces showed the hours and minutes in a digital format with large numerals on rotating discs. In its anniversary year, IWC honours this pioneering achievement with the IWC Tribute to Pallweber Edition “150 Years”. This model is limited to 500 watches and has a stainless steel case, a blue 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.
