I am a new member.
Can anyone help please with identification of date of manufacture etc of a Ladymatic that I have inherited?

Inside the back cover is the following information:
5515006 (would this be the serial number or case number I wonder)
9 .375 k plus what appears to be a square symbol inside a circle.

The movement is 24 jewels.
Am I correct in that the 9 and .375 indicates a 9 ct case?
Watch seems to keep reasonable time.
Some photos attached.

 

The serial no. is on the movement close to the rim at 1 o'clock in the picture. Post it and we can give you more data.
