1980's jeweled Kit Cat Clock

Hi, this is my new kid Cat Clock model B1 I believe this model to be made after 1982 but before 1990 because this model is a electric plug-in with rhinestones
I would love to know more about this kit at Clock like are the rhinestones Swarovski crystals or glass rhinestones or plastic where can I buy replacement jewels also I don't know if the back was replaced with a B1 model because I also don't know if this model ever had rhinestones this model maybe a b8 model with a B1 back cover
This clock works great only if you rhinestones missing Anymore information would be great thanks
