Great article about Habring double chronograh

[ATG]

Apparently Richard Habring invented the 'Dopplechronograph' for IWC 20 years ago....

Excellent article here on Hodinkee Great Job...

Well... it might be going a bit far to say that Habring "invented" the Doppel for IWC, but he certainly did develop the rattrapante (or Schleppzeiger) module which was patented by IWC, and in so doing "democratised" and advanced a formerly exclusive watch complication. Also true enough that he achieved this development--and participated on numerous other projects for IWC--as a twenty-something 'wunderkind'. I have a huge amount of respect for Habring.

From his own atelier I really like the (somewhat exciting) Foudroyante which also incorporates the "dead beat seconds" or jump seconds into a "time only" watch model (NB. this is a mechanical calibre, no quartz here):

Rolex sweeping seconds hand... be damned!

Oh... and you've gotta love this, too. Habring has developed a "no pusher" chronograph operation system. The chrono is completely controlled from the crown. Thus the crown operating system "COS":

Finally, for all those lovers of the Sinn EZM1 with its philosophy of pared down to essentials only... Habring will soon have available a watch which takes this philosophy a step further:



The Central Minutes Chrono (ZM):
- COS
- no sub-dials
- no constant seconds
- central minutes counter (à la Lemania 5100)

OK, its not military... but I love the purity of the idea.

Well, I'm no expert on Habring or IWC, and I've never seen any information which details, in exact technical terms, what these modification were. However, be that as it may, my understanding is that Habring's first project at IWC--even before his development of the rattrapante module, and his work redeveloping IWCs Tourbillion for the minute repeater and perpetual calendar--was to work on improving the IWC calibre 375, or that is, the ETA 2892-2. Apparently, one of the main areas Habring worked on (although there was probably more to it than this) concerned problems with the automatic winding system. ETA adopted these improvements when they later developed the 2892-A2.

How "solid" is this information (part of the question from the original post)? Well, there seems to be a good deal of reference to the Habring/IWC contribution to the ETA 2892-A2, and this from people who seem to spread far less than their share of myth and hyperbole... the latter of which is rife in WISdom. ;-)
