IWC Schaffhausen is to present a tribute to the Pallweber digital jumping hour pocket watch as part of the brand’s 150th Anniversary celebrations in 2018, only now they have redesigned it a wristwatch.

In June 1884 IWC’s second owner, Johann Rauschenbach-Schenk, signed a deal with Salzburg watchmaker, Josef Pallweber, to secure the rights to his Pallweber digital jumping hour mechanism, which displayed the hours and minutes as numerals within apertures rather than using hands and dials.

The resulting Pallweber pocket watch became IWC’s first watch with a ‘digital’ display but the energy required for toothed cogs to advance the numeral discs – especially the single minute disc which advanced once every 60 seconds – meant power reserve was limited. Over the next six years, the International Watch Company produced around 20,000 examples of the design before ceasing production.

The 150th Anniversary Jubilee Collection Tribute to Pallweber Edition 150 Years comes in a 45mm 18ct red gold case with wire lugs and a flattened onion crown, the modern Pallweber translates the original design faithfully with two concentric black circles linking the hour numeral window and the small seconds upon its spartan white lacquer dial.

Limited to 250 pieces, IWC has developed a separate wheel train with its own barrel to power the advancement of the jumping numerals, and a locking mechanism connects to the watch’s main wheel train once every 60 seconds and then locks it again. The 10-minute wheel is then advanced by the single-minute wheel and the hour wheel advanced by the 10-minute wheel with a 60 hours power. IWC is awaiting a patent on this development.

The IWC Tribute to Pallweber Edition 150 years is clearly a surprising watch, whether in terms of style, of inspirations or mechanical solutions. It certainly is not the usual IWC watch, yet it really feels captivating and perfectly executed. Price for this 250-piece limited edition is EUR 38,000
