WTF!!!! $5900
The real thing (Le Coultre, Jaeger) in nice condition are sold on Ebay fairly regularly for a couple hundred.
From the Hodinkee ad;
These clocks were functional objets d'art, capable of telling the time and acting as an aide-mémoire for weary travelers. They have also become a source of fascination among the HODINKEE team, which is why, after stumbling upon a veritable stockpile of untouched vintage movements during a trip abroad a few years ago, we knew we had to take the opportunity to share them with the world. After years of development and a design process involving multiple iterations and prototypes, we're proud to introduce the HODINKEE Eight-Day Travel Clock. It's a contemporary version of the classic clocks we've long appreciated, designed from the ground up at our New York office as a tribute to those early pioneers of travel.
This one recently sold on Ebay for a $100 (complete with aide-memoire by the way)
