I think I understand your point of view, Fab. Essentially, if Zenith had produced these limited editions wholly in-house . . .
. . . with minimal alterations, then there would be no issues: they would be Zenith chronometers thru and thru.
That would be ideal from a purists (much less Purists!) perspective. I suppose the reason Zenith embellished the project with outside participation was to maximize returns on what presumably is a limited supply of movements. If the supply were larger, or if Zenith resumed production of the 135 as Omega did with the 321, the price would be closer to thirteen big ones than a hundred thirty big ones.
