I think that the 3201 movement was for the 50th Anniversary Speedmaster only and will not be produced again. The 3201 is really just a stripped c.3313.
Omega is expected to introduce an
in-house chronograph movement derived from the new 8500/8501 caliber in 2010 to coincide with the winter Olympics in Vancouver. I suspect that eventually the new in-house movement will be used in all of Omega's chronographs, with the exception of the Speedmaster Pro which will continue to use Lemania.
