The Omega Constellation has never been one of the main Omega watches on my radar. This fact is interesting to me since I am a big fan of Omega watches overall. If you speak to Omega you learn something interesting that makes sense if you think about it.
Personally I think the Omega Constellation needs to be at least 40mm wide (up to maybe 42mm wide) for the US market. What I have for review is the steel Omega Constellation Co-Axial Day-Date 38mm watch ref. 123.10.38.22.01.001 and the 18k Sedna gold Omega Constellation Co-Axial 38mm ref. -ablogtowatch
