I received the slick sheet on the Omega 1164 by snail mail. It was very nicely prepared and delivered in a clear plastic protective sleeve. It didn't give any real detail most of us already know, but it did confirm that there are 25 jewels in Omega's version of the Valjoux 7750. It also confirms that the movement in the SM Chrono is the 1164 now (replacing the 1154).

Unfortunately it did not specify the difference between the 1154 and the 1164.

: I just got this from Omega (see below). When they send the
: seperate mail on the details of the Omega 1164, I will post
: it here as well.
