I'm quite surprised that I still haven't seen any pictures of the new Breguet movements with the silicium escapement bits. I've seen the macro shots of the bits in question, but I have yet to see a full movement shot of either the Cal. 591A (which probably looks a heck of a lot like the Cal. 591 (former Lemania 8810)) or the Cal. 777Q. Does anyone have any pictures of this mythical beastie?
but I guess - as you mention - it will look similar to the 8810...
Actually a nice marketing move - to put a nowadays seldem used caliber back into the front line.. . Nice also because it is a great caliber!
