While I really appreciate the technique, skill and effort represented by the engraved versions, I still prefer the purity and cleanliness exhibited by Peter's enamel dials. Of course, I wouldn't complain if I was lucky enough to acquire a PSM/Engelbarts piece myself... 
Regardless, you have two fantastic versions of the Piccadilly there!
I hope to see both of them (and you!) at dinner in two weeks. I'll be there on Saturday.
cheers,
