The "Memoris 200th Anniversary"

 From Louis Moinet -

200 years is a long time, and frankly quite worthy of celebration!  This chronographic bijoux is from the good folks at Louis Moinet.  This is a white gold cased single button (mono-pusher) chronograph,  with a dial that is at once distracting and beguiling.   

The main time indication rests at 6 o'clock and is of enamel.  The remainder provides a skeletonized look and feel.  But there is one more flourish - notice the stars sprinkled around the outside portions?

That would be the mainplate which has been bestowed with stars thanks to a new technique utilizing a specially adapted graving tool.
