omega 14391-62

Hello dear. I recently bought this Omega. I've had my eye on this for a while, it used to work but now it doesn't and the seller has reduced the price to about $330 for the entire set pictured. Do you think this is a good price? Where I live, such sets are very rare, so I couldn’t resist buying it. I understand they are from 1962, the crystal and crown are original, as is the strap and bracelet.
Tell me please, is the dial original?
I will be sending them to my mechanic soon and he will work on their mechanism.
I would like to take this opportunity to ask how you wind your automatic watch? I have omega 2992, 503cal. I don't wear them often and they require winding, but my mechanic advised me not to wind them by hand as I might damage them. This is true?
Thanks everyone in advance!
Sincerely!
Sorry for my English, I'm using a translator

Hi, did the translator eat pictures of watches?😁

I see them. Didn't they load?

Now: yes 👍 But text is russian? now.

original IMO: box, steel-bracelet, strap (?), clasp , glass, case ,

dial looks OK - should have SWISS MADE at "6". What are your concerns?

Sorry, my phone constantly translates the text from Russian to English and vice versa, every time I edit.
yes, on "6" there is this inscription.
I have little experience, so I wanted to make sure I wasn’t mistaken in originality!)

Wait for the specialists in the western time-zone 😉

thank you very much👍
