Is it worth selling a rolex for parts vs saving to get it repaired then selling it?

Hey guys,

I have an old ladies Rolex from the 1960's that was my grandmothers'. I have been debating on selling it lately for parts because the band broke and it is missing the little turny thing. And with needing to get my pain meds filled and bills to pay, well you know how it is.
Someone told me I should take it to a jeweler and have them repair it then sell it, but that would cost quite a lot of money and I only have around $50 a month after my bills. Should I just set that money aside to try and repair it or is the watch really not worth that much anyways so I should just sell it as as parts?

Here is a pic of it, I do not know much about it.
