MSNWATCH I have a quick question are the heights of the crystal different between the 30t2scrg and the 30t2rg I am just guessing (thinking) that the 30t2rg would have a lower profile crystal and the 30t2scrg would have a higher profile do to the sweep second hand. At one time I had vintage Omega case parts catalogs I let a friend borrow them big mistake on my part. When I asked for the catalogs back he told me he did not know where they were or what happened to them. Live and learn!
