It was quite an extensive article. The owner of SWATC understood that his watches are fashion decor, but said that he was going to stop selling to high end watch companies in order to force them to again make their own movements. He died before end of year. Whether that policy was carried out is a question. I have no doubt they make the other parts, because style is what sells the watches.
I don’t know about Germany, but in America I would say that most likely 1/3 to 1/2 of the retail cost of the watches you mentioned is marketing. A billboard or full page ad for a mass consumer item makes sense, but for an Omega? An Good example some years ago, is Rebok shoes. This was a shoe cheap that sold in US for $15. New management put $35 marketing in each shoe and was able to sell more of the same cheap $15 shoe at $50 than at $15.
My Gubelin watch had to be sent back to Switzerland for repair because the replacement part had to be hand made. Watch is pre-war.
I was presented with a very expensive gold Weil quarts battery powered watch. I doubt that Weil makes the movements, probably the same as my battery run Backwards Goofy. In fact, even looks less substantial. Also, I don’t believe that Disney makes watches.
I know that there are some watchmakers who still make watches, but they are usually in the $100,000 price range.
Do you really believe that Leica makes their own “push and shoots” or their own electronic components?
