So often, in the watch collecting community, there are stories which go almost entirely untold. Lost artefacts which are miraculously found in impossibly perfect condition. This is very true of the story of this week's edition of My Watch, with Constantin Rau, a passionate collector and @Porsche obsessive, whose attention to the finest detail of movement references, dial configurations, car parts and specifications is remarkable, to say the least. We sat down with Constantin in London’s South Kensington club to discuss his obsession and that one special piece that he could never part with. Link in the bio.
