Bruno,
Well....I don't know. maybe another look out of that plastic wrapping may change people's view:



The whole case is curved...either concave or convex like a sculpture...almost not a flat surface in sight except for the back. The case making process must have been complexed and expensive with multiple die-stampings and reheating to relieve the strains in the metal microstructure.
The blue enamel crown is very attractive.
