I don't know anything about watches, except what I've read here the past few months. I received this watch in my late mother's belongings. I believe it may have belonged to her mother, as my mother was born in 1935. This sat in her jewelry box my entire life. My sisters put it in the throw away pile but I thought it was worth holding on to. I can't find much of anything online about the Diana, which I believe may be from 1930. Wondering if it is rare and if there is value? I haven't been able to identify the band, other than it says Kreisler Quality Gold Cont 025 USA. Thanks for any info, this seems to be a very informative site. Willing to sell.
