La Magique - More information please

Hi, I have just joined the Omega Forum and have a "La Magique" ladies pendant watch. I will post pics later when I discover how to do it! I read that only 261 of this type were produced. Is that just watches, or both please? If you know the numbers of each, I would be grateful. Does anyone know the number of the battery as well as I don't have one installed now and can't remember why it was removed? Many thanks, Bob
