As part of its jubilee collection, the Company is proud to present the IWC Tribute to Pallweber Edition "150 Years" with a jumping-numeral display for the hours and minutes. The design of the watch, which is available in limited editions in platinum, 18-carat 5N gold or stainless steel, leans heavily on the historic original. The dials are painstakingly coated with up to twelve layers of high-quality lacquer and were inspired by the enamel dials featured in the original Pallweber watches. And just as back then, the windows for the digital display are inscribed with the words "Hours" and "Minutes".
The case conceals a new technical feature: "We developed a brand-new solution from scratch for the technically demanding job of moving the display discs," confides Satzke, "which we've registered for patent." In the original Pallweber movements, the display discs were advanced by cogwheels with unequally spaced teeth. When a gap between the teeth occurred, the power from the mainspring was transferred directly to the starwheel on the one-minute disc. This design, however, led to fluctuations in balance amplitude and made the movements susceptible to wear and tear. And the fact the energy required to advance the display discs was tapped from the barrel meant that the power reserve was somewhat limited.
