Even more embarrassing is that official Rolex personnel will never distinguish the authenticity of the watch. So people began to guess. Some people think that because this situation has already happened, the watch may install the 6239 panel on the 6240 case during the production process. Others believe that the watch was privately modified by a person or department who wanted to profit from the auction. The authenticity of this watch is hard to say. In fact, the 6239 with the 'character line' has not been distinguished for a while, until people find the 'character line' 6239 on the Rolex advertisement, which really proves the true identity of the watch. And the 'single line' 6240 has no definite identification. Everything is guessing, everything is guessing.
