Your in-depth reply is much appreciated and above and beyond any answer I could have hoped for.
When you say the movements are sometimes different between competitor models and normal series, how so? Are the less decorated or different movements all together? I was under the assumption that they had 2894's with a DD chrono module (thru the years I'm looking at, so until 2003). Do you know off hand if the 8392 (2003) had a difference?
Thank you once again
