Just got this on trade. A professionally assembled, with original Omega parts, Speedymoon. Effectively a 145.0809 powered by a 1866 instead of 866. Any intentions to pass off as more than what it is will be addressed when you flip it over. Not for the purists, but it has the best of the speedymoon and current moonphase in a single package. +Acrylic crystal +Matte dial without rings +Display back +Does not have a collectible premium, wear it with abandon -Omega did not assemble it -The purist in me feels a little less pure. It is my first 'watchco' type watch. Will see how i bond with it.
