There are at least two companies in the US who are advertising the ability to recreate Apple's gold alloy (at least optically if not scientifically). Here's one. The watch looks pretty good to me. This particular company also offers rhodium plating for people who bought SS and want to maintain that look but add a protective scratch resistant layer.
