1897 Gold Pocket Watch

by Unknown

I have an 1897 gold pocket watch. The markings on the watch don't give any clues to who made it. On the front of the case the letters "GAJ" are engraved. The back has "1897" engraved. On the dial is the letter "d" in a flag. Inside there is also a letter "d" in a flag and also the letter "WC". The serial number is 819632. I guess the size to be 18 and the watch does work.

Does anyone know who might have made this gold pocket watch?
