If this were the case, every Zeiss Conquest owner could take recourse against Zeiss for misleading!
Leica has a factory in Portugal, some binoculars are manufactured there, the company uses the same resources as the main factory in Germany, but the glasses must be labeled "Made in Portugal", even if a few steps take place in Germany!
Even the Noctivid wears "Portugal" when the main work is not taking place in Germany!
You can't just use the label "Made in Germany" unless there is a noticeable proportion in Germany, there are numerous court rulings that clarify that.
Such a well-known company as Zeiss can hardly circumvent these rules without receiving sustained charges.
