Errr i assume you know the rotary engine is not a tag heuer hor?
i was using that last picture to reinforce the idea that tag heuer should be focusing on the auto racing concept, as a natural progression from their heuer racing range.
the v4 monaco for instance was designed to emulate a car engine with bearings, belts etc...
i think designing the rotary "w a n k e l engine" inspired movement is actually is fun, like the ulysee nardin "freak".
Should be easier than their mikrotimer flying 1000 chrono..the former is about geometry, the latter brings analog to digital territory withy 1/1000th of a second accuracy.
so much nice tech and heritage in tag heuer, such a pity to see them just go after the fashion crowd.
