I have a pocket watch received from my Grandfather that has no identifiable marks - no name (or anything) on the face, no stamps, no numbers, etc. I would think there must be marking on the movement, but the watch is so thin that there are no seams, no way to open the watch that I can see, other than removing the crystal. I would appreciate any direction as to possible manufacturer, and / or anyone (ideally in Canada) who might have the expertise to open this watch to get more information. apologies in advance for quality of pictures. Note - I posted here as my Grandfather worked in the jewellery business in London (Garrrard's) Thanks in advance.
