Girard Perreguax, Louis Vuitton, Ralph Lauren and Speake-Marin. Personally, I would be upset if I spent US$345k on a watch with the same movement as two fashion brands. Nevermind whether the movement is “in house” - that just doesn’t seem right to me. At that price, I would expect serious innovation - or at least I would at least expect the brand to acknowledge the provenance of the movement clearly on their website/press release. But I understand that others may think differently, and are happy for brands to act in this way.
