The hand engraving you see inside the case is likely notes from the various watchmakers who have serviced the piece. Each watchmaker uses her/his own code so there no way to decipher the markings. the chain and knife would not have been supplied by the manufacturer of the watch and would have been added as a personal preference. They could have been supplied by the jeweler when the watch was new. My grandfathers 'knife' was a "pipe tool" as he smoked a pipe. I'm not sure what the numbers on the case lip represent.
