I have got a Tissot lady watch, and I have some questions about it. If anybody knows this type I would really appreciate all info what could be shared. Based on the serial number it is probably original Tissot and released in 1965. but is see some interesting handmade scratched numbers also on the back.I hope it is readable from the pictures. Has anybody already seen similar signs? Does this mean that watch is serviced and the service guy signed the cover?Thanks in advance for all info or idea.
