Interesting that the market absolutely loves enamel pieces from Patek, while similar quality works from UN and some others attracts very little attention. Regarding the movement- yes, it is not special being ETA-based, even if the highest grade one. But is the movement in enamel Pateks that much better? And is it really that important in this kind of art watches? I don't think so. All in all - I love these enamel UNs and consider them grossly undervalued. Do you agree? If yes - why do you think it is the case? Weakness of the brandname or lack of interest in enamel works overall? SM
