Despite being completely unpronounceable, this watch is just plain outright cool. The brainchild of Max Busser (MB&F) and Felix Baumgartner (URWERK), it is the first watch to use an eccentric planetary transmission system for the timekeeping mechanism – i.e. the same geometry as the Wankel engine. (Curiously, there’s only one ratio of inner to outer satellite that actually permits the three distinct chambers to be formed; any other ratio doesn’t seal at all). The minutes are read off the red tips of the upper ‘rotor’, with the hours on the level below. There is no seconds indication, but there is a power reserve on the back of the watch.

I believe these are the first photos outside the official press release, and I was told that the watch is a working production prototype – which means non-final parts and finishing, and some potential tool marks in places as befits an engineering experiment…

Many thanks to Ian Skellern at C3H5N3O9.

This series shot (hastily) with a Nikon D800E and AFS 60/2.8 G Micro. It wasn’t a commercial shoot, so please excuse me if I missed a spot or two. All images can be clicked on for larger versions.
