My Bilogy. Got the Seamaster a month ago and the speedmaster yesterday. It was available for a week and nobody bought it, so don't say it's sold out.
Meanwhile, I placed my deposit the minute I saw the press release and have not heard a peep from the Chicago OB.
Cheers for the side-by-side with the Geophysic. It gives a great frame of reference on size. Looks like apart from the lugs it would wear slightly smaller than the Geophysic.
