You are in the right place and you can perhaps follow my same path, because it was a lot like where you want to go.
This is my dad's wedding watch. He rarely wore the ring, but he always wore the watch. He gave it to me because he didn't move enough to keep it wound.
And then my mom died.
Obviously I put the original bracelet back on (in the right in this pic) and he wore it through her funeral and at some time after until he again realized that he wasn't moving enough to keep it wound.
Because honor, I searched and found a NOS copy of the bracelet.. and in fact two, to make it long enough for me to wear!
Your dad's bracelet, you are so lucky. You can get a brand-new Fixoflex bracelet to fit you, while of course keeping his original for history.
I don't know where you are but, USA? I have a watchmaker you can trust.
While this pic suggests the dial isn't so bad, it's a bit worn and some dipstick "watchmaker" scratched the dial. Whenever he was asked if he wanted to refinish the dial? He
always said no. Therefore, I never shall.
It has zippo to do with what it's worth, because no one cares. It's your dad's watch.
Here's an anecdote.
I was given my grandfather's trumpet when I was a stupid kid. I didn't treat it well. After I decided to start playing again when I was 40 years old, I had it restored. It might have been worth a few hundred dollars. $2500ish after? It was still worth a few hundred dollars.
My mom seeing me play it before she lost her mind? Her father's horn?
Priceless.
We'll take care of you. Don't give any attention to "worth" because it's not relevant.
You're fine.
