After selling off my GO PanoMatic Lunar Steel and looking at perpetuals since last October or so, I went down to one of my friendly ADs during lunch today and ordered the GO Senator Perpetual Calender PT LE 50 pieces.

This marks a second coming to GO for me. It does not meet all of my criteria for a Perpetual but most and I am a sucker for platinum and roman numeral indicators.
Will post pics of actual watch when I get it which should be in a couple of week's time.
In the meantime, enjoy the stock pic of the watch and thanks to all (especially Dr No) for their input into my search.
