Watches/Can anyone get me started with this Watch.1 message

Dear Connoisseurs,

Does anyone know more about this watch. In terms of everything actually.

Year in which. Battery replacement. Cleaning Tips. Value. Matrial.

I am so curious and the internet is gone after two weeks .......

Thanks in advance, I am very curious.
