> Take the Omega Speedmaster 105.003

An interesting example. If they had been assembled under license by a little-known NASA contracted-company in Illinois, would you still be as keen on it?

Until 1979 Soviet cosmonauts used their standard pilot-issue Strela watch, including on EVAs. In the West it was branded and sold as Sekonda[0]. Without the cachet of a luxury brand and extensive marketing it is almost unknown despite being just as functional as the Speedmaster.
