Without preservation, the preservation rate is not high. According to the article about Watch House, first of all, ETA movements were widely used in Cartier several years ago, such as the well-known Cal.267 1 and Cal.2892A2 Although these are ETA's ace movements, their stability is beyond doubt, but compared with some homemade movements that have been processed and polished, there are obviously fewer stories and technologies. The advantages and disadvantages of ETA movement are very obvious, which is also what many cousins care about when buying watches. Tens of thousands to more than 300 thousand blue balloons all have the same movements, which is obviously unacceptable to ordinary cousins. However, this is the style of jewelry brands like Cartier. Secondly, the reason why Cartier watches have a "low preservation rate" is the Cartier brand itself. Jewelry brands give people the impression that "watches are unprofessional", and the previous "Eta Movement" deepened the impression that "watches are unprofessional". In fact, there is a certain misunderstanding. The history of Cartier brand making watches is actually not short, even longer than many mainstream watch brands. It's just that Cartier brand has a great influence in the field of jewelry, which makes people feel that watches are just a "side-by-side" business besides jewelry. Therefore, Cartier's hedge ratio is not high.
