The listing, Gorgeous Ladies Watch has ended.
This is a fine piece of jewelry, but very impractical timepiece. Since my aesthetic is contemporary and practical, it is not for me, but perhaps it is for you.
The maker is not evident, but the back seems to say, ”JAPAN” and “Stainless Steel”.
I just spent $6.99 to get a new battery and it seems to work just fine.
Thanks for looking.
Oh, yes,...the answer to your question is, "No, those are not real diamonds. If I thought so, I would sell it to a jeweler."
