Sure, sorry - that's even mentioned above that it essentially is used in some Breguet, Patek, and VC watches. I guess I meant that Omega themselves never produced the movement, and it hadn't been produced for them as the 321 since 1960. I just don't see the ROI for them to switch from the 1861. Although I suppose it could be possible if they decided to produce a VERY expensive limited edition that they might commission some "321" to be made. I was too emphatic in my original post.
