The Omega Constellation Double Eagle model has been the biggest change of the Constellation line since 1982. Before that, only the 1952-1969 era counts. In the 70s there was no real clear and defined Constellation design. The Manhattan series, which seems to be some kind of??code name for the post-1982 Constellation models, didnt change much until 1995. Most post-Constellation series were referred to as Constellation95 models. Not too long ago, Omega did some restyling and admitted to the big bold hype of most other brands out there. Although it is hard to think of it as a hype anymore. Big watches are here to stay, maybe next to smaller watches again.. but definately no hype (or fad)..A TimeZoner by the name of mjb, published a small pictorial of the Omega Constellation Double Eagle in the Omega Forum. This Double Eagle has the co-axial movement, based on Omega caliber 2500B (based on the ETA 2892-A2).Click here for more pictures!
