The EOS (named for the Greek goddess of the dawn) was one of the most talked about watches of the 2001 Basel Fair (before it was called Baselworld), and features a great complication: a sunrise/sunset indication.1  An interesting complication, and a rare one as well, the sunrise/sunset indicator shows the time the sun rises and sets in your location.  To our knowledge, we’ve only seen three other wristwatches not made by Martin Braun that have this complication: the AP Royal Oak 26603, the Jaeger-LeCoultre Reverso Grande Complication à Triptyque, and the Vacheron Tour de l’Ile. The last two on the list are super complicated watches. In fact, the Vacheron was the most complicated wristwatch ever made back in 2005 when it was released, oh and it cost in the ballpark of $1.5M when it came out. Not even the super-complicated Patek Grandmaster Chime or the Franck Muller Mega Aeternitas 4 have this complication.

So how does this sunrise/sunset complication work?  The watch has a set of cams which are created for a specific longitude and latitude.  This specific watch is set for Stamford, Connecticut, which is just 35 miles outside of New York City, and thus has basically the same sunrise and sunset time as NYC.  These cams are connected to the hands, showing the sunrise and sunset times.  So the cams advance once per day, thus moving the hands the appropriate amount to show the new day’s sunrise and sunset times – a brilliant system that took Braun five years to think up, calculate, and create.1

Aesthetically, it’s hard not to like this watch. It’s got a coin-edged case, and cool textured sunburst pattern on the dial. This particular watch has a MAB 88 movement, which uses a Franck Muller movement as the base.  For a little background, the Franck Muller group purchased Martin Braun’s company in 2007.  Before that purchase, the EOS was made by building on top of an ETA base.  Collectors seem to prefer the the MAB 88 version.
