Coming back to this, luxury watches manufactured in Switzerland have the words "Swiss made" in tiny lettering at the very bottom of the dial, one word either side of the numeral for 6. See here for a 1960s example of an Omega Sea Master watch:
The point about Omega and other similar luxury watches is that part of their prestige lies precisely in their having been made in Switzerland. I therefore find it hard to believe that any would have been made in the US just to evade tariffs - even if the necessary watch-making skills were available there.
However, if you know otherwise please do clarify the situation.
Ross 14kt cases
What were the years(beginning to end) for the importation into the US of Omega movements to be cased by Ross Case co? Where was Ross located? Were the only cases used by Ross for Omega solid gold? This one encases a non-Seamaster cal 354 Automatic circa 1954.
