Inherited my dad's watch

[RolieKid]

Hey all, I am new to the Rolex forums and the world of Rolex. My dad past away not too long ago, and I inherited his watch. He bought the watch after I was born in 1980 I am told, and he wanted to give it to me after he past. It's now mine. It needs to be cleaned, and it needs a battery. I bought it to Rolex NYC for a new battery and cleaning, but they said it has a lot of oxidation and needs a complete overhaul at around 2k plus tax. Apparently, I cannot post a pic as I am a new member. It's a 1980 yellow gold rolex president with a diamond bezel and diamond dial where the arabic numbers are. I hope that describes it better. Once I am able to post a pic, I will.

I wanted to trade it in for a white gold or stainless steel daytona, but my siblings (which seem a bit jealous) and my mother are adamantly against me trading it for something else. Saying that your father will turn over in his grave and if you change it, I will take it back. She can't, as it was willed to me, but I do not want to cause any ripples in the family.

I was thinking of exchanging the diamond bezel for a regular one and changing the dial to a black one with gold prongs, but open to suggestions from the community. I am not a flashy person, so I really do not know when I'd wear it. He loved this watch. Not to get too personal, but when he was in the ER due to a heart attack, he felt the nurse take off his watch. We all gasped as he gathered enough strength to attempt to fight off the nurse. My mother was able to calm him down and she took it off of him. He passed on 12 hours later. So, yea, it's still hard for me to trade it in for something else. It's just too flashy for me to wear daily. Not sure how I'd be able to pull off wearing a 20k watch.

Anyways, open to suggestions. Thank you all in advance for some guidance.
