A bit of mystery here! This 18 carat gold pocket watch has a backside with female and angel and it is a model with seperate key (size 8 or 9). Which makes is likely antique because later models did not use keys anymore.
The size is in between male and female at 37/38 mm. Female size was usually 22-25, male usually closer to 45 mm.
What I do know it that it runs right away, I just received a key to try it. A bit oxidating on the inner part as you can see on picture 6.
Most important, the emaille dial is perfect and the hands have some kind of stone in them, very nice detail! Without key, but you can buy them everywhere. I will send fully insured worldwide.
A really great and unusual collectors item!
