  • Catalogue Essay

    The present IWC Split Seconds is being consigned by the man who developed the split seconds chronograph movement at IWC: Richard Habring. It is a true piece of horological history, dating from the early 1990s, a period when mechanical watchmaking was making a comeback and research and developments made would shape the market for the years to come.

    Habring joined IWC in 1991 – then helmed by the great Günther Blümelin - as technical director in charge of the development of a cost efficient and easy to assemble split seconds chronograph.
    It is important to underline that a split seconds mechanism, due to the incredible low tolerances, is one of the most difficult complications to master and expensive to produce. Habring’s task was therefore one that requested out of the box thinking, talent and a bit of madness.

    The first decision was t0 use the workhorse ETA 7750 chronograph movement but to remove the winding system (and thus make the movement hand wound) the date and hour counters to make the movement thinner. A split seconds mechanism needed to be developed that would fit onto the 7750, the Eureka moment came after studying a Heuer pocket watch with split seconds housing a Valjoux 9 caliber – which explains the fact that the present IWC is accompanied by a Heuer split seconds pocket watch and a disassembled Valjoux 9 movement.

    Habring inspired himself from the Valjoux 9, to create a split seconds mechanism that did away with a column wheel, was thin and fit atop the 7750.
    IWC’s split seconds chronograph was born, first into the Pilot Doppel Chronograph and rapidly into what was the world’s most complicated timepiece at the time: The Destriero Scafusia featuring a perpetual calendar, minute repeater, tourbillon and split seconds chronograph.

    When it was decided to have the iconic Portugueser model house the newly developed split seconds chronograph Habring created a prototype- the present example-to show Blumelin what could be done with this new model and as such took steel parts from steel parts from the Il Destriero Scafusia and applied a high grade finish with a nickel plated movement with Geneva waves on the top bridge and balance cock. To be able to admire the movement he also cut an opening on the caseback.

    These modifications did not make it into the final production and Habring’s prototype (which explains the lack of numbering on the case and movement) remained unique. He wore it as his everyday watch until he left in the early 2000s to create his own brand with his wife Maria: Habring2 .

    The present prototype is accompanied by an incredible set of accessories, a Heuer pocket split seconds pocket watch, a disassembles Valjoux 9 movement, a painting of the Doppel Chronograph, an copy of International Watch (in German) with an article on Habring from his time at IWC, Habring’s business card from IWC and a letter from Habring confirming this was his watch and a signed graphic novel about Habring2.

    Not only a historically important timepiece, the proceeds of the sale will be going to charity, the biggest portion going to Caritas Austria and the rest to support local schools and associations.
    Caritas is a non governmental organization helping the poor both locally and abroad.
