What I do know 100% about the watch is that it was given to me in 1969. It has my name engraved on the back which was done in 1969.
I have been told it was gifted to my grandfather for his 10th birthday in 1923 ( whether that information is correct or not is what I am trying to determine)
The watch has 15 Jewels and was purchased in Canada. I dont know if the knife and chain were originally added to the knife or if they were added in the 60's
Inside the case is some hand written information like "B123HT" and "NN7765 followed by some cursive text which comes up in the image for inside the case"
I would like to know what year the watch was manufactured and weather it needs any form of insurance. Thank you for your time and expertise.
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.
The case itself has a serial number that is not usually that closely related to the watch. Generally, an ID will include the movement number and databases online reflect this, as cases can easily be swapped. The ID of the piece is the mechanism, in short, the opposite of motor cars.
The case numbers can be used to ID the case manufacturer but don't necessarily mean the watch is by them. Watch manufacturers often utilized outside case makers.
The Shield indicates a manufacture date of 1929 for the movt.
