In 1884, IWC manufactured the first so-called Pallweber pocket watches. These innovative timepieces showed the hours and minutes in digital format with large numerals on rotating discs. In its 150th anniversary year, IWC honours this achievement with the IWC Tribute to Pallweber Edition “150 Years” (Ref. IW505101). This exclusive pocket watch is limited to 50 pieces. It is housed in an 18-carat red gold case, elaborately decorated with guilloché work and worn on an 18-carat red gold chain. The pocket watch features a white dial with a lacquered fi nish and white display discs. The small seconds hand is blued.

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”. Two windows in the spring cover reveal the hours and minutes, so the time can be read even when it is closed. The case also features a closed dust cover on the backside.

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 operates independently guarantees precision and a 60-hour power reserve.
