I was in Osaka last week and visited a few BV boutiques. At one of the boutique, I was so closed to getting the Cabat in Ebano. The SA told me they just received it that morning but when I looked inside, there is no number engraved on the metal plate. Other Cabats have their numbers engraved. The SA had no explanation for it and they were just as puzzled. I then went to other boutiques and theirs have numbers. I was wondering if the new ones have no numbers engraved. Can anyone advise?
