1960’s Seamaster - Pursuing Restoration

Hi all, first post here and hoping you can point me in the right direction.

I recently came into possession of an old watch of my grandfather’s. From my own research, it appears to be an early 1960’s Seamaster, possibly a ref. 14700, but I’m unsure of whether it’s an automatic or a hand-wind. As far as I can tell, it was originally purchased new (possibly in India), hasn’t been worn for at least the past few decades, and has sat in a relatively dry desk. There are no original papers, and the box also doesn’t appear to be original.

I’m planning on having it serviced/restored as it is in quite poor condition, but as this is my first vintage watch, I would love some advice on next steps.

I’ve heard conflicting opinions regarding Omega factory services vs independent specialty watchmakers (Nesbits, etc.), mostly revolving around the preservation of original parts. In your opinion, what is the best way to go about restoration given its significant damage, and what would be a reasonable estimate? Price is not really an issue, but I’ve read wildly differing estimates ranging from a few hundred to north of 3k.

Thank you! I appreciate your help in advance.

Very cool watch - love those models from that era. And from my understanding they have excellent movements that can often be serviced to run beautifully again.

Nice Watch, would also recommend a good service for the movement from a reputable watch maker.

I mailed mine and had to wait a while

After a service I am sure this watch will serve you well for many years. Your grandfather would be happy
