Piaget's Mooning You

Every year for the past few years there has been an auction of watches to benefit research into Duchenne Muscular Dystrophy, the Only Watch Auction.  The idea is that a bunch of companies donate watches, unique in some way, to the auction, and they're sold, with all proceeds donated.  Sometimes the watches are truly unique, sometimes they are a variant on a production model (red dials seem to be popular as red is the color of Monaco, where the auction is held) and sometimes they are simply the first of a numbered edition.
   In 2009 Piaget's contribution was a variant on their Emperador Coussin moonphase watch.  As 2009 was the 40th anniversary of the moon landing, they modified the lunar display to be a more realistic lunar surface and added an engraving of Neil Armstrong's bootprint.  The moon on this model is made of 18kt white god that has been reticulated, a process that causes the thin surface of the material to melt, flow a bit and then crumple on itself when it cooled.  There are still traces of the oxidization that is a side effect of this on the outer edges of the moon.
