I have a question about the movements that IWC uses. I have read on this site and others that the Portofino watches use modified ETA movements, while the salesman at the local IWC boutique assured me that all IWC movements are now made "in-house." Is that true? What about the Portuguese line, does that use "in-house" movements?
Also, I have been told that Jaeger LeCoultre makes a different movement for each of its watches, so that even if one of the models is not in limited edition, it still has its own unique movement, is that the same for the "in-house" IWC movements? Which other watches do the same as JLC?
